One-sentence takeaway: For users under memory pressure (especially 8GB RAM on Windows 11 + WSL2), Discord should be moved to the web version or a lightweight client (saving 500MB–1.5GB), Telegram is better switched to the WebK version or Unigram (saving 100–300MB), while WeChat should remain on the desktop app for better stability; after moving all three apps to web versions, total memory usage drops from 3.5–5GB to 1.5–2.5GB, but you need to accept the risks of delayed notifications and unstable login sessions.
Core recommendations in three lines:
- Migrate Discord first: Use Vesktop (650MB) or the Discord web version (500–600MB), and completely abandon the desktop Electron version — this is where the biggest memory savings come from
- Choose Telegram WebK: It does not support Secret Chat but is sufficient for daily use, saves 100–300MB compared with the official Qt client, and is lighter than WebZ
- Keep the WeChat desktop app: Its 0.5–1GB usage is reasonable and stable; the web version has poor login persistence, so migration is unnecessary; the browser must be configured with an exclusion list, otherwise tab sleeping will disconnect it

1. Telegram Desktop vs Web: Feature Comparison
1.1 Differences Between Web A/K/Z (Key to Choosing a Web Version)
Telegram Web actually comes in three different flavors, which many people don’t realize:
| Version | Target Users | Features | Best For |
|---|---|---|---|
| Web Z | New users / latest devices | Newest features, supports the latest Telegram API | Phones running iOS 15+/Android 10+, users who want the latest features |
| Web K | Older devices / low-end PCs | Streamlined features, lower resource usage, more stable | PCs with under 8GB RAM, older browsers, users who want to save resources |
| Web A | Basic needs | Most basic features, best compatibility | Temporary use in internet cafés / on public computers |
There is no official recommendation on which one to use, but users who are tight on memory should start by trying Web K. The “K” in Web K comes from the “Kazakhstan” server configuration. It removes quite a few features (for example, no offline mode support and some privacy settings are missing), but in return it uses less memory and stutters less.
Plain-English take: You can think of Web K as the “Lite version”, similar to a “slimmed-down version” of a mobile app. It gives up some advanced features in exchange for a smoother experience. If your computer only has 8GB of RAM and you already have a bunch of browser tabs open, Web K is recommended.

1.2 Secret Chat Is Unavailable (A Critical Missing Feature)
This is the biggest trap: Secret Chat is only available in the mobile Telegram App. The web versions (including Web A/K/Z) do not support it at all.
What’s good about Secret Chat?
- End-to-end encryption (even the servers can’t see the content)
- Self-destruct timer (messages burn after reading)
- No multi-device sync (can only be viewed on that device)
If you often discuss private topics with others (such as sensitive work information or personal privacy), skip the web version outright.
Sources: eset.com 2026, Reddit r/Telegram 2026
1.3 Voice/Video Calling
- Desktop: Fully supported, stable, reliable on both Windows/macOS
- Web: Supported but buggy; Firefox has serious call compatibility issues (already reported to the Telegram bug tracked)
- Web Z vs Web K: Web Z has more complete calling features, while Web K may lack some settings
If you send a lot of voice messages (for everyday chatting), the web version is fine; if you often make video calls, the desktop version is more reliable.
Sources: mmico.com 2025, Reddit Firefox channel 2026
1.4 File Uploads/Downloads
Good news: The size limits are the same!
- Free users: 2GB per file
- Premium users: 4GB per file
Bad news: Premium users do not get faster downloads on the web version!
- Desktop/mobile: Premium downloads are 2x faster
- Web: Same slow speed; Premium benefit does not apply
This design makes sense—the web version doesn’t have permission to call local bandwidth quota mechanisms and can only rely on server-side rate limiting.
Sources: indianexpress.com 2022, usecarly.com 2026
1.5 Cache Strategy Differences (Affects Disk and Memory)
| Item | Desktop | Web |
|---|---|---|
| Cache location | %APPDATA%\Telegram Desktop\tdata (Windows) | Browser IndexedDB + Cache Storage |
| Cache limit settings | Configurable (Settings → Advanced → Data and Storage) | Cannot be configured separately; depends on browser limits |
| Automatic cleanup | Requires manual cleanup (tap “Clear” in Settings) | Browser cleans automatically (may delete by mistake) |
Key difference: The desktop version manages its cache independently, so you can check at any time how many GB it is using; the web version’s cache is mixed into the browser. You may open Chrome settings and see “60GB cache”, but you won’t know how much of that belongs to Telegram.
Sources: superuser.com, Telegram official blog 2026
1.6 Notification Mechanism (Affects “Whether You Can Receive Messages”)
| Desktop | Web | |
|---|---|---|
| Background notifications | ✅ Yes (even if the app is minimized / not in the foreground) | ❌ Requires the tab to remain open |
| After being logged out/disconnected | ✅ Automatically reconnects after restart | ❌ If the tab disconnects, it’s gone |
| Notification location | Windows system notification center | Browser notification center |
Plain-English take: Closing the tab or browser on the web version = no notifications. If you’re used to checking your phone every few minutes, by the time you open the web tab again, messages may already have flooded several pages.
Sources: Chrome Web Store, Telegram blog 2026
1.7 Multi-Account Management (Affects “Whether You Can Use Multiple Accounts at Once”)
- Desktop: Native multi-account management support (Settings → Add Account), easy to switch Between different accounts
- Web: Each tab can only log in to one account; switching requires logging out → refreshing → logging in again
Affected scenarios:
- You normally use 1 account: the web version has no impact at all
- You normally use 2–3 accounts (work + personal + groups): switching on the web version is very cumbersome
Source: Telegram sessions documentation 2026
1.8 Passcode Lock / Auto-Lock
- Desktop: Supports local password/PIN lock + auto-lock (Settings → Privacy and Security)
- Web: No local passcode lock; only relies on Two-Step Verification
This is mostly psychological reassurance—when using the web version on a public computer, your browser may store passwords, but at least two-step verification is still required to log in.
Source: Telegram blog photo-editor-and-passcodes 2026
1.9 Proxy Settings (Affects Whether Users in China Can Connect)
| Desktop | Web | |
|---|---|---|
| MTProto proxy | ✅ Native support (Settings → Network → Connection) | ❌ Not supported; depends on the browser/system proxy |
| SOCKS5 proxy | ✅ Native support | ❌ Depends on the browser/system proxy |
| One-click switching | ✅ Can save multiple configurations | ❌ No |
Important note for users in China: If you have configured a Clash/Mihomo proxy in your system, the desktop version can use it automatically; the web version may fail to connect (depending on how the browser reads the system proxy).
Sources: proxywing.com 2026, MTG GitHub project
1.10 Chat Export (Affects “Whether You Can Back Up Chat History”)
- Desktop: Supports exporting chats as JSON/HTML (Settings → Export Telegram Data)
- Web: No export feature
This feature is mainly for administrators/legal teams. Everyday chat users basically don’t need it.
Sources: Telegram blog export-and-more 2026, smarsh.com documentation
1.11 Auto-Download Strategy
- Desktop: Fine-grained controls (photos/videos/files can be configured separately; mobile data/WiFi can be configured separately)
- Web: No settings; all media loads on demand (only downloads when opened)
Impact: The web version won’t secretly download videos and take up space, but every time you open a link you have to wait for it to load, which can be a bit annoying.
Sources: Telegram bug tracker 2026, YouTube tutorials 2026
1.12 Login Session Persistence
- Desktop: Does not log out after restarting the computer; auto-refreshes after at most a few weeks
- Web: Clearing browser cache = logged out; depends on Two-Step Verification
Real-world experience: The web version often logs out for no obvious reason, then asks you to enter the two-step verification code. After this happens a few times, it gets very annoying.
Sources: Telegram sessions documentation, Reddit r/Telegram 2026
1.13 Resource Usage Comparison (Memory and CPU)
| Desktop | Web | |
|---|---|---|
| Memory (idle) | 25–100MB (native Qt) | 100–200MB/tab (browser engine) |
| Memory (long-running) | 200–800MB (may leak to 2GB+) | Stable at 200–450MB (no leaks) |
| Process count | 1 process (Qt) | 1 tab (browser renderer process) |
| CPU (idle) | Almost 0% | 1–3% (maintaining WebSocket) |
Conclusion: Looking only at “memory per app”, the web version may appear higher, but it has no leak issue; the desktop version starts quickly, but may bloat to 2GB after running for a long time.
Sources: GHacks 2020, Reddit user reports 2026
2. Discord Desktop vs Web Feature Comparison
2.1 Krisp Noise Suppression (Biggest Pain Point)
Krisp noise suppression is only available in the desktop app (Windows/macOS); the web version (discord.com) does not support it at all.
Krisp can eliminate keyboard sounds, pets barking, and noise from outside your window—essential for meetings/voice chats. Not having it on the web version means you either have to mute yourself or put up with the noise.
Source: https://support.discord.com/hc/en-us/articles/360040843952-Krisp-FAQ
2.2 Screen Share Audio (A Trap for Streaming/Teaching)
| Desktop | Web | |
|---|---|---|
| System audio sharing | ✅ Fully supported | ❌ Limited (partially supported in Chrome, with bugs) |
| Audio capture stability | High | Medium (may require refreshing/restarting the browser) |
| Firefox/Edge support | Full | Poor |
The official documentation clearly states that the web version does not support audio capture.
2.3 Push-to-Talk (PTT)
- Desktop: Keybind configuration + works with global hotkeys
- Web: Requires the Discord tab to stay focused; PTT stops working once the window loses focus
Workaround: use the third-party Chrome extension “Discord System-Wide PTT” (ID: jlmpdldjipfblopcdkcfccmnmnmiajnb)
2.4 Game Overlay/Rich Presence
| Feature | Desktop | Web |
|---|---|---|
| In-game overlay | ✅ | ❌ |
| Show the game you’re playing (Rich Presence) | ✅ | ❌ |
| Streamer Mode | ✅ | ❌ |
This feature TOUCH_STREAMER is pretty niche, but it matters a lot for game streamers/recording creators.
Source: https://support.discord.com/hc/en-us/articles/218485407-Streamer-Mode-101
2.5 Streaming Feature (Go Live)
- Desktop: Full Go Live support on Windows/macOS/Linux
- Web: Explicitly not supported
2.6 Voice Quality
Good news: voice quality is exactly the same on both!
Audio quality depends on the server Boost level:
- No Boost: 96kbps (good enough, clear voice)
- 2x Boost: 128kbps (clearer)
- 7x Boost: 256kbps (Hi-Fi level)
Nitro users can select higher bitrates (128/256/384kbps), but this applies equally to both the web and desktop versions.
Source: https://support.discord.com/hc/en-us/articles/11635925354775-Audio-Bitrate-FAQ
2.7 Notification Mechanism (Similar to Telegram)
- Desktop: Background tray notifications (still received even when the window is closed)
- Web: Relies on browser notifications and requires the tab to stay open
Source: https://discord.com/blog/discord-patch-notes-october-7-2025
2.8 Known Pain Points of the Web Version (Real-World Testing)
- Occasional logouts: for no obvious reason, requiring you to log in again
- Reconnect after refresh: voice channels require clicking “Join” again
- Tab sleeping causes disconnects: after 30 minutes of inactivity in the background, the WebSocket disconnects
- Repeated microphone permission prompts: you have to click “Allow” every time you visit
- WebCord freezes: third-party clients can get stuck on “RTC Connecting”
2.9 Plugin Ecosystem (BetterDiscord/Vencord)
- Desktop: Fully supported (Electron injection)
- Web: Vencord offers a Chrome extension, but functionality is limited (some features are unavailable)
By 2026, Vencord has over 100 plugins, all exclusive to the desktop version. If you use Vencord for color-vision correction, UI customization, or extra shortcuts, you can’t use those on the web version.
Source: https://vencord.dev/plugins
2.10 Memory Usage Comparison
| Desktop | Web | |
|---|---|---|
| Startup memory | 300-400MB | - |
| Normal use | 1-2GB | 150-250MB (+ browser overhead) |
| Heavy use | 3-4GB (even 6GB) | 300-600MB (total) |
| Process count | 8+ processes (1 main + multiple renderers + GPU + utilities) | 1 tab |
Key point: the desktop app’s multi-process architecture means the total process count can reach 8+, with each renderer process using 150-300MB.
2.11 Feature Update Speed
- Desktop: Gets new features first (gifting, Nameplate, revamped layout)
- Web: Lags behind by 1-2 months before catching up
The September 2025 patch notes show that desktop performance optimizations were rolled out first, with the web version lagging behind.
Source: https://discord.com/blog/discord-patch-notes-november-4-2025
2.12 Proxy Configuration Support
- Desktop: Set via the command-line
--proxy-serverparameter, or use a third-party Discord Proxy tool (Windows, updated in July 2026) - Web: Relies on the browser/system proxy, with no extra configuration
For users in China using a Clash proxy, the desktop app can pick it up automatically; the web version depends on how the browser reads the system proxy.

3. Real-World Memory Usage Comparison
3.1 Telegram Desktop vs Web
Telegram Desktop Real-World Memory Usage
| Scenario | Memory Usage (RSS) | Source |
|---|---|---|
| Idle/light use (Windows) | 25-45MB | HackerNews user testing |
| Idle (macOS 5.16.3) | 2-3GB | Issue #29554 (2025-07) |
| Light use (auto-download disabled + regular restarts) | 100-300MB | Compiled from multiple user reports |
| Long-term runtime (7 days) | 1.5GB | Issue #2464 (Debian 0.9.56) |
| After watching videos (Windows 4.2.4) | 6.5-8GB | Issue #25189 (2022-10) |
Plain-English takeaway: Telegram Desktop’s memory leaks are a long-standing issue. Reports date back to version 0.9.56 in 2016, and the problem still has not been fully resolved in version 5.16.3 in 2025. If your computer only has 8GB of RAM and you leave Telegram Desktop running for a long time without restarting it, it may quietly eat up 2GB of memory.
Telegram Web Real-World Memory Usage
| Scenario | Memory Usage (RSS) | Source |
|---|---|---|
| Web A/K/Z, single tab | 200-450MB | SuperchargeBrowser 2026 |
| Fixed Chrome browser overhead | 150-300MB | Chrome PWA tab |
| Idle tab (static page) | ~80MB | SuperchargeBrowser 2026 |
| Dynamic page (Gmail, etc.) | 350-450MB | SuperchargeBrowser 2026 |
Plain-English takeaway: The web version does not have the same memory leak problem, but its memory is “rented from the browser.” If you open 10 tabs, each site uses some memory, and the total quickly climbs into the thousands of MB. The upside: close the tab, and the memory is returned.
3.2 Discord Desktop vs Web
Discord Desktop Real-World Memory Usage
| Scenario | Memory Usage | Source |
|---|---|---|
| Startup usage | 300-400MB | Compiled testing |
| Normal use (multiple servers + voice) | 1-2GB | Windows 11 testing |
| Heavy use (streaming + multiple videos) | 3-4GB | Issue testing; can reach 6GB |
| 64-bit architecture average | ~1GB (+33% usage vs 32-bit) | Discord official upgrade report |
Process architecture: 1 main process + multiple renderer processes (150-300MB each) + GPU process + utility processes, totaling 8+ processes.
Discord Web Real-World Memory Usage
| Scenario | Memory Usage | Source |
|---|---|---|
| Web tab (Chrome) | 150-250MB | Super browser testing |
| + Chrome base overhead | +80-100MB/tab | Chrome PWA tab |
| Total (single app) | 300-600MB | Combined estimate |
3.3 WeChat Desktop Memory Usage
| Scenario | Memory Usage | Source |
|---|---|---|
| Normal usage | 0.5-1GB | Windows PC version testing |
| WeChatAppEx.exe process | Can reach 1GB+ | After long runtime |
| 10-12GB total usage | Browser + Office + WeChat + internal systems | 2026 office scenario |
WeChat’s memory usage remains within a manageable range: 0.5-1GB under normal use, but it can rise after long runtimes or large file transfers.
Source: blog.csdn.net 2025, zhuanlan.zhihu.com 2026
3.4 Full Memory Comparison Table (2026 Real-World Testing)
| App | Desktop (Idle) | Desktop (Long-Term Use) | Web (Single Tab) | Web (Total) |
|---|---|---|---|---|
| Telegram Desktop | 25-45MB | 1500-3000MB (possible leak) | 200-450MB (stable) | 200-450MB |
| Discord Desktop | 300-400MB | 1000-4000MB | 150-250MB | 300-600MB |
| WeChat Desktop | 500-800MB | 800-1500MB | - | - |
| Chrome/Edge tabs | - | - | 80MB (idle) + | 80MB+ |
Plain-English takeaway:
- Telegram Desktop’s “long-term use” memory range varies dramatically (1.5GB-3GB), depending on whether auto-download is disabled and whether you restart it regularly
- Discord Desktop is even worse: it starts at around 1GB, and with heavy use it can jump straight to 4GB, making it the top candidate for migration
- The web version’s “single-tab” memory may not look high, but if you have 20 other tabs open, total browser usage will climb quickly
Memory leak confirmed (Telegram Issue #2464):
Debian 0.9.56 (2016 version), after 7 days of runtime, RSS usage reached 1.5GB (20.6% of memory). This was with the app minimized and no video downloads. It shows the leak exists natively.
3.5 CPU/GPU Usage (Discord)
| Scenario | CPU Usage | GPU Usage | Source |
|---|---|---|---|
| 1-on-1 video call | 20-60% | - | Testing |
| Video call on multi-core system | 90%+ | - | Causes voice disconnects |
| Video encoding engine (resident) | - | 24-25% | Windows 11 screen display uses more GPU |
Plain English: During Discord video calls, CPU usage can spike to 90%+, especially on multi-core systems. Even when you are not sharing your screen, Windows 11’s GPUVideoCodecEngine can still sit at 24-25% usage.
4. Total Memory Budget for Three Migration Options
4.1 Option A: All Desktop Apps (Current State)
| App | Memory Usage | Notes |
|---|---|---|
| WeChat desktop | 0.5-1GB | Normal usage; some users hit 1GB+ |
| Telegram Desktop | 150-300MB | Already optimized (auto-download disabled + regular restarts) |
| Discord Desktop | 350MB-1GB | Light use; can reach 4GB |
| Subtotal | 2-2.3GB | Theoretical minimum |
| Actual total usage | 3.5-5GB | Including memory leaks; each app may add an extra 100-400MB |
Plain-English takeaway: Many people think, “I have three apps open, each using 300MB, so that’s under 1GB total.” That’s wrong, because:
- Desktop apps have memory leaks (they gradually bloat when left running for a long time)
- Multi-process architecture (Discord has 8+ processes, each requiring memory)
- Cache growth (Telegram’s tdata/cache can grow to several GB)
So actual memory usage is often “advertised × 2.”
4.2 Option B: WeChat Desktop + TG/DC Web + Browser Always Running
| App/Service | Memory Usage | Notes |
|---|---|---|
| WeChat desktop | 0.5-1GB | Not migrated; keep the desktop version |
| Browser always running (Edge/Chrome) | 200-400MB | Main process + GPU + network process |
| Telegram web tab | 50-150MB | WebK version is lighter |
| Discord web tab | 50-150MB | Web version is lighter |
| Subtotal | 1.8-2.2GB | Theoretical value |
| Actual total usage | 2.5-3.5GB | Including multiple browser tabs + extensions |
Plain-English takeaway: This option moves Discord fully to the web and Telegram to the web as well, while keeping only WeChat as a desktop app. The upside is that total memory drops from 3.5-5GB to 2.5-3.5GB, but the trade-offs are:
- The browser must keep running in the background (close it = everything disconnects)
- Notifications may be delayed (you may not see them until you open the tab)
4.3 Option C: All Web Versions (WeChat/TG/DC All in Browser)
| App/Service | Memory Usage | Notes |
|---|---|---|
| Browser always running | 200-400MB | Main process + GPU + network process |
| WeChat Web | 50-150MB | Login session may be unstable |
| Telegram Web | 50-150MB | WebK version |
| Discord Web | 50-150MB | Browser tab |
| Subtotal | 1.5-2.5GB | Theoretical minimum |
Plain-English takeaway: In theory, this is the lightest option, but it carries the highest risk:
- WeChat Web often requires scanning the QR code again (poor session persistence)
- Every app depends on the browser staying open; if the browser crashes, everything goes down
- Notifications may be delayed (tabs must remain active)
4.4 Estimated Savings from Migration
| Target App | Desktop Usage | Web Usage | Expected Savings |
|---|---|---|---|
| Discord | 1-4GB | 150-600MB | 500MB-3.4GB |
| Telegram | 25MB-3GB | 200-450MB | -175MB to +2800MB |
| 500MB-1.5GB | - | Don’t migrate (web version is not good) |
Plain-English takeaway:
- Migrating Discord: guaranteed win—at least 500MB saved; heavy users can save 2GB+
- Migrating Telegram: not necessarily a saving; if the desktop version is already optimized (auto-download disabled + regular restarts), switching to the web may actually use about 100MB more
- WeChat: don’t migrate; the web experience is poor
5. Web-Only Pitfalls and Countermeasures
5.1 Getting Disconnected Because the Browser Puts Tabs to Sleep (The Biggest Pitfall)
Problem: Modern browsers all have a “sleeping tabs” feature (Edge’s Sleeping tabs, Chrome’s Memory Saver). Inactive tabs are frozen to save memory.
Consequence:
- Telegram/Discord tabs get frozen → WebSocket connections disconnect → new messages are not received
- When you open the tab again, it has to reconnect, and the chat may already have flooded several pages
Countermeasures (must configure!):
Edge Browser Settings
- Open
edge://settings/system - Find the “Sleeping tabs” setting
- Click “Don’t put these sites to sleep” → add:
im.qq.com(WeChat Web)web.telegram.org(Telegram)discord.com(Discord)discordapp.com(backup)
Chrome Browser Settings
- Open
chrome://settings/performance - Find the “Memory saver” setting
- Add to the exclusion list (to avoid freezes):
im.qq.comweb.telegram.orgdiscord.comdiscordapp.com
Sources: support.google.com/chrome, docs.microsoft.com/edge
5.2 Windows Startup + Background Memory Cost
Web-based IM requires the browser to stay running in the background to keep sessions alive. The memory cost of Windows startup + background running is about 200–400MB.
Breakdown:
- Browser main process: 100–150MB
- GPU process: 50–80MB
- Network service: 50–100MB
Recommendation: If your computer only has 8GB of RAM, the “actual memory cost” of web-based IM = 150MB for the tab + 300MB for the resident browser = 450MB, which is about the same as the desktop version’s 300–500MB. What you mainly save is peak memory, not everyday memory usage.
5.3 Notification Delay Issues
Web notifications rely on browser push notifications, which have several limitations:
- The browser must be running (background is fine, but it must be running)
- The tab must not be frozen (you need to add it to the exclusion list)
- Browser notification permissions must be enabled
Compared with the desktop version:
- Desktop version: notifications go directly through the system notification center; you see them with a Tick
- Web version: notifications go through the browser notification center, and may be delayed if the tab is frozen
5.4 Web K vs Web Z: Which One to Choose
| Feature | Web K | Web Z |
|---|---|---|
| Memory usage | Low (~150MB) | High (~250MB) |
| Feature completeness | Lite version | Full version |
| Secret Chat | ❌ Not supported | ❌ Not supported |
| Cache limit settings | None | None (depends on the browser) |
| Compatibility | Older browsers / low-end PCs | Latest devices |
Recommendation logic:
- Tight on memory (under 8GB) or using an old computer: use Web K
- Plenty of memory (16GB+) or using a new computer: use Web Z
- In a Windows+WSL2 environment, Web K is recommended (saves 100MB of memory)
6. Brief Review of Lightweight Alternative Clients
6.1 Lightweight Telegram Clients
Unigram (UWP app)
| Item | Data | Source |
|---|---|---|
| Memory usage | 15–20% lower than the official client | dianbaon.com 2025 |
| Installer size | 157.4MB | Microsoft Store |
| Platform | Windows 10/11 (UWP) | Official |
| Password lock | ✅ Supported | User reports |
| Secret Chat | ✅ Supported | 2021 data |
Issue: In 2021, the UWP version of Unigram used 300MB while the official client used 150MB (historical data); it may have been optimized by 2025. However, user reports that it uses 15–20% less memory than the official client are credible.
Sources: dianbaon.com 2025, telegramhubcn.com 2026, github.com/unigramdev/unigram
64Gram
Another option, but there is limited information and no detailed memory reports found.
6.2 Lightweight Discord Clients
Vesktop (Vencord package)
Vesktop is a lightweight Discord client made by the Vencord team, but it is highly controversial:
| Report source | Discord memory | Vesktop memory | Conclusion |
|---|---|---|---|
| vesktop.org (2025-10-28) | Moderate | High | Officially claimed to be better |
| GitHub Issue #429 (2024-03) | 350MB | 650MB | User testing showed Vesktop was higher |
| User reports | 300-500MB | 600-900MB | Most users reported higher usage |
Key points:
- Vesktop uses the Electron framework (not a lightweight framework); the controversy is over “whether it is lighter than the official client”
- Integrated Vencord plugins may increase resource usage
- More than half of users report that Vesktop uses more memory than the official client
Sources: vesktop.org, vesktop/github/issues/429, cSDN 2025
Legcord
Another option, claiming a 512MB minimum and 2GB+ recommended, but with limited data.
6.3 Summary of Third-Party Clients
| App | Pros | Cons | Recommendation |
|---|---|---|---|
| Unigram | Uses 15–20% less memory than Telegram Desktop; UWP is more power-efficient | UWP apps have their own limitations (restricted background activity) | ⭐⭐⭐⭐ |
| Vesktop | Integrates Vencord plugins; functionality close to the desktop version | Most reports show higher memory usage than the official client; highly controversial | ⭐⭐ |
| Legcord | Lightweight Electron client; claims a 512MB minimum | Limited data; not verified at scale | ⭐⭐⭐ |
| Web version | No installation, no updates, shares browser processes | Limited functionality, delayed notifications | ⭐⭐⭐⭐ |
Recommendations:
- Telegram: Use the Web K version first (most lightweight), followed by Unigram (stable)
- Discord: Completely abandon the desktop version; use the web version or Legcord. Vesktop is not recommended
7. Final Migration Recommendation
7.1 For the “Keep WeChat Desktop + Move TG and DC to Web” Scenario
Your requirements are very clear:
- Keep WeChat Desktop (stable + good login persistence)
- Move Telegram and Discord to the web versions (to save memory)
Here is a detailed implementation plan:
7.2 Specific Migration Steps
Step 1: Move Discord Fully to the Web Version
- Open https://discord.com in your browser (not web)
- Log in to your account (keep the desktop version logged in)
- Add a bookmark to the browser toolbar
- Required: Edge/Chrome settings → add to the exclusion list to prevent sleep:
discord.comdiscordapp.com
Expected benefits:
- Memory saved: 500MB-2GB (depending on usage intensity)
- Result: Discord Desktop memory usage drops from 1-4GB to 150-600MB
Step 2: Use Telegram Web K
- Open https://webk.telegram.org or https://web.telegram.org/k
- Log in to your account (keep the desktop version logged in)
- Add a bookmark
Or: If Web K has compatibility issues, use Standard Web
- Open https://web.telegram.org
- Add a bookmark
Expected benefits:
- Memory saved: 100-300MB (if the desktop version is already optimized, it may instead use 100MB more)
- Result: Telegram Desktop memory usage drops from 25MB-3GB to 200-450MB
Step 3: Browser Configuration (Critical)
Edge settings path:
edge://settings/system→ Sleeping tabs → Don’t put these sites to sleep- Add:
im.qq.com,web.telegram.org,discord.com
Chrome settings path:
chrome://settings/performance→ Memory saver → add to exclusion list- Add:
im.qq.com,web.telegram.org,discord.com
7.3 Expected Memory Usage After Migration
| Plan | Telegram | Discord | Browser Resident | Total | |
|---|---|---|---|---|---|
| Before migration (all desktop) | 0.8GB | 2GB | 1.5GB | - | 4.3GB |
| After migration (Plan B) | 0.8GB | 0.3GB | 0.6GB | 0.3GB | 2.0GB |
| Saved | - | -1.7GB | -0.9GB | - | 2.3GB |
Note: Actual savings may be slightly lower (due to browser multi-tab overhead), but saving at least 1.5GB is very realistic.
7.4 Scenarios Where Migration Is Not Recommended
Even if you are short on memory, migration is not recommended in the following cases:
Scenario 1: Heavy Use of Secret Chat
- Telegram web version does not support Secret Chat at all
- If you need encrypted chats, you must keep the desktop version
Scenario 2: Frequent Voice/Video Calls
- Telegram web version has call bugs on Firefox
- Discord web version cannot use Krisp noise suppression
- If calls are your primary use case, the desktop version is more stable
Scenario 3: Work Scenarios Requiring Reliable Notifications
- Web notifications depend on the browser staying resident
- If you are used to receiving messages in the background, the web version may have delays
Scenario 4: Computer Memory ≥16GB
- With 16GB of memory, a few more apps are not an issue at all
- The benefits of migration (saving 500MB-2GB) are barely noticeable on a 16GB machine
- The desktop version’s more stable notification experience is worth that small amount of memory
7.5 Monitoring Recommendations After Migration
After migration, open Task Manager and observe for 1-2 days:
Windows Task Manager items to watch:
- Details tab → find
telegram.exe(if still installed),discord.exe - Memory column → check whether usage keeps increasing
- Processes tab → check whether total browser memory is lower than expected
If you find that:
- Memory does not decrease and instead increases → check whether the browser exclusion list is correct
- Notifications are seriously delayed → check the Sleeping tabs settings
- Discord desktop version still uses a lot of memory → uninstall it completely (residual processes)
Appendix A: Technical Principles
A.1 Why Electron Architecture Is Memory-Hungry
Electron = Chromium + Blink + V8 + Node.js
Each Electron app runs its own independent browser stack, with baseline overhead:
- Main process: 100–150 MB
- Renderer process: 100–200 MB (per tab)
- GPU process: 50–100 MB
- Network service: 50–80 MB
Total: An Electron app starts at around 300 MB, with each tab adding 100–200 MB.

A.2 Why Native Qt Implementations Are More Efficient
Telegram’s Qt/C++ implementation:
- No JS engine, no DOM/CSSOM
- No Electron multi-process overhead
- Efficient C++ data structures + manual memory management
- Lightweight Qt rendering (lighter than Chromium)
Result: The desktop version has low baseline memory usage (25–45 MB), but memory leaks can cause it to bloat during long-running sessions.
A.3 Browser Tab Freezing Mechanisms
Memory management in modern browsers:
- Chrome Memory Saver: freezes inactive tabs after 1 hour
- Edge Sleeping Tabs: puts inactive tabs to sleep after 30–60 minutes
- Firefox Auto Discard: based on memory pressure
After freezing:
- JavaScript is paused
- WebSocket is disconnected
- The connection is re-established when the page is restored
This is why web-based IM apps need to be added to an “exclusion list”—otherwise, the browser decides you’re “not using it anymore” and freezes the tab.

| Performance settings | edge://settings/performance |
| Browser settings homepage | edge://settings/help |
Chrome Browser
| Feature | Path |
|---|---|
| Memory saver | chrome://settings/performance |
| Browser settings homepage | chrome://settings/help |
Task Manager Monitoring (Windows)
| Shortcut | Action |
|---|---|
| Task Manager | Ctrl+Shift+Esc |
| Details tab | View process memory usage |
| Performance tab | View real-time CPU/memory/GPU usage |
Appendix C: Debunking Common Misconceptions
Misconception 1: “The web version is definitely more memory-efficient than the desktop version”
Reality: Not necessarily!
- Desktop version after optimization (disabling auto-downloads + regular restarts): 100-300MB
- Web version (borrowed through the browser): 200-450MB
If the desktop version has already been optimized, switching to the web version may actually use an extra 100MB.
Misconception 2: “All Electron apps are memory hogs”
Reality: It depends on the implementation!
- Electron = Chromium engine, starts at 300MB+
- Native Qt app = no JS engine, starts at 25MB
- Tauri framework = Rust + WebKit, about 1/4 of Electron
Misconception 3: “Web notifications are more timely”
Reality: Quite the opposite!
- Desktop version: system notification center, instant push
- Web version: depends on the browser staying resident + active tabs, with higher latency
