Telegram & Discord: Desktop vs Web Deep Comparison (2026)

Real memory measurements of three mainstream messaging apps, desktop vs web: switching Discord to web saves 500MB-1.5GB, Telegram to WebK saves 100-300MB, and keeping WeChat desktop is recommended.

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:

  1. 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
  2. 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
  3. 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:

VersionTarget UsersFeaturesBest For
Web ZNew users / latest devicesNewest features, supports the latest Telegram APIPhones running iOS 15+/Android 10+, users who want the latest features
Web KOlder devices / low-end PCsStreamlined features, lower resource usage, more stablePCs with under 8GB RAM, older browsers, users who want to save resources
Web ABasic needsMost basic features, best compatibilityTemporary 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.

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.

1.5 Cache Strategy Differences (Affects Disk and Memory)

ItemDesktopWeb
Cache location%APPDATA%\Telegram Desktop\tdata (Windows)Browser IndexedDB + Cache Storage
Cache limit settingsConfigurable (Settings → Advanced → Data and Storage)Cannot be configured separately; depends on browser limits
Automatic cleanupRequires 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”)

DesktopWeb
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 locationWindows system notification centerBrowser 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)

DesktopWeb
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)

DesktopWeb
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 count1 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.

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)

DesktopWeb
System audio sharing✅ Fully supported❌ Limited (partially supported in Chrome, with bugs)
Audio capture stabilityHighMedium (may require refreshing/restarting the browser)
Firefox/Edge supportFullPoor

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)

Source: https://www.reddit.com/r/discordapp/comments/1rqccfu/discord_in_web_browser_no_way_to_get_push_to_talk/

2.4 Game Overlay/Rich Presence

2.5 Streaming Feature (Go Live)

  • Desktop: Full Go Live support on Windows/macOS/Linux
  • Web: Explicitly not supported

Source: https://riverside.com/blog/how-to-stream-on-discord

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)

  1. Occasional logouts: for no obvious reason, requiring you to log in again
  2. Reconnect after refresh: voice channels require clicking “Join” again
  3. Tab sleeping causes disconnects: after 30 minutes of inactivity in the background, the WebSocket disconnects
  4. Repeated microphone permission prompts: you have to click “Allow” every time you visit
  5. WebCord freezes: third-party clients can get stuck on “RTC Connecting”

Source: https://github.com/SpacingBat3/WebCord/issues/690

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.

Heavy use3-4GB (even 6GB)300-600MB (total)
Process count8+ 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-server parameter, 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

ScenarioMemory Usage (RSS)Source
Idle/light use (Windows)25-45MBHackerNews user testing
Idle (macOS 5.16.3)2-3GBIssue #29554 (2025-07)
Light use (auto-download disabled + regular restarts)100-300MBCompiled from multiple user reports
Long-term runtime (7 days)1.5GBIssue #2464 (Debian 0.9.56)
After watching videos (Windows 4.2.4)6.5-8GBIssue #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

ScenarioMemory Usage (RSS)Source
Web A/K/Z, single tab200-450MBSuperchargeBrowser 2026
Fixed Chrome browser overhead150-300MBChrome PWA tab
Idle tab (static page)~80MBSuperchargeBrowser 2026
Dynamic page (Gmail, etc.)350-450MBSuperchargeBrowser 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

3.4 Full Memory Comparison Table (2026 Real-World Testing)

AppDesktop (Idle)Desktop (Long-Term Use)Web (Single Tab)Web (Total)
Telegram Desktop25-45MB1500-3000MB (possible leak)200-450MB (stable)200-450MB

WeChat Desktop500-800MB800-1500MB--
Chrome/Edge tabs--80MB (idle) +80MB+

Plain-English takeaway:

  1. 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
  2. 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
  3. 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)

ScenarioCPU UsageGPU UsageSource

4. Total Memory Budget for Three Migration Options

4.1 Option A: All Desktop Apps (Current State)

AppMemory UsageNotes
WeChat desktop0.5-1GBNormal usage; some users hit 1GB+
Telegram Desktop150-300MBAlready optimized (auto-download disabled + regular restarts)
Discord Desktop350MB-1GBLight use; can reach 4GB
Subtotal2-2.3GBTheoretical minimum
Actual total usage3.5-5GBIncluding 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:

  1. Desktop apps have memory leaks (they gradually bloat when left running for a long time)
  2. Multi-process architecture (Discord has 8+ processes, each requiring memory)
  3. 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/ServiceMemory UsageNotes
WeChat desktop0.5-1GBNot migrated; keep the desktop version
Browser always running (Edge/Chrome)200-400MBMain process + GPU + network process
Telegram web tab50-150MBWebK version is lighter
Discord web tab50-150MBWeb version is lighter
Subtotal1.8-2.2GBTheoretical value
Actual total usage2.5-3.5GBIncluding 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:

  1. The browser must keep running in the background (close it = everything disconnects)
  2. 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/ServiceMemory UsageNotes
Browser always running200-400MBMain process + GPU + network process
WeChat Web50-150MBLogin session may be unstable
Telegram Web50-150MBWebK version
Discord Web50-150MBBrowser tab
Subtotal1.5-2.5GBTheoretical minimum

Plain-English takeaway: In theory, this is the lightest option, but it carries the highest risk:

  1. WeChat Web often requires scanning the QR code again (poor session persistence)
  2. Every app depends on the browser staying open; if the browser crashes, everything goes down
  3. Notifications may be delayed (tabs must remain active)

4.4 Estimated Savings from Migration

Target AppDesktop UsageWeb UsageExpected Savings
Discord1-4GB150-600MB500MB-3.4GB
Telegram25MB-3GB200-450MB-175MB to +2800MB
WeChat500MB-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

  1. Open edge://settings/system
  2. Find the “Sleeping tabs” setting
  3. 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

  1. Open chrome://settings/performance
  2. Find the “Memory saver” setting
  3. Add to the exclusion list (to avoid freezes):
    • im.qq.com
    • web.telegram.org
    • discord.com
    • discordapp.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:

  1. The browser must be running (background is fine, but it must be running)
  2. The tab must not be frozen (you need to add it to the exclusion list)
  3. 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

FeatureWeb KWeb Z
Memory usageLow (~150MB)High (~250MB)
Feature completenessLite versionFull version
Secret Chat❌ Not supported❌ Not supported
Cache limit settingsNoneNone (depends on the browser)
CompatibilityOlder browsers / low-end PCsLatest 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)

ItemDataSource
Memory usage15–20% lower than the official clientdianbaon.com 2025
Installer size157.4MBMicrosoft Store
PlatformWindows 10/11 (UWP)Official
Password lock✅ SupportedUser reports
Secret Chat✅ Supported2021 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 sourceDiscord memoryVesktop memoryConclusion
vesktop.org (2025-10-28)ModerateHighOfficially claimed to be better
GitHub Issue #429 (2024-03)350MB650MBUser testing showed Vesktop was higher
User reports300-500MB600-900MBMost users reported higher usage

Key points:

  1. Vesktop uses the Electron framework (not a lightweight framework); the controversy is over “whether it is lighter than the official client”
  2. Integrated Vencord plugins may increase resource usage
  3. 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

AppProsConsRecommendation
UnigramUses 15–20% less memory than Telegram Desktop; UWP is more power-efficientUWP apps have their own limitations (restricted background activity)⭐⭐⭐⭐
VesktopIntegrates Vencord plugins; functionality close to the desktop versionMost reports show higher memory usage than the official client; highly controversial⭐⭐
LegcordLightweight Electron client; claims a 512MB minimumLimited data; not verified at scale⭐⭐⭐
Web versionNo installation, no updates, shares browser processesLimited 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

  1. Open https://discord.com in your browser (not web)
  2. Log in to your account (keep the desktop version logged in)
  3. Add a bookmark to the browser toolbar
  4. Required: Edge/Chrome settings → add to the exclusion list to prevent sleep:
    • discord.com
    • discordapp.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

  1. Open https://webk.telegram.org or https://web.telegram.org/k
  2. Log in to your account (keep the desktop version logged in)
  3. Add a bookmark

Or: If Web K has compatibility issues, use Standard Web

  1. Open https://web.telegram.org
  2. 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:

  1. edge://settings/system → Sleeping tabs → Don’t put these sites to sleep
  2. Add: im.qq.com, web.telegram.org, discord.com

Chrome settings path:

  1. chrome://settings/performance → Memory saver → add to exclusion list
  2. Add: im.qq.com, web.telegram.org, discord.com

7.3 Expected Memory Usage After Migration

PlanWeChatTelegramDiscordBrowser ResidentTotal
Before migration (all desktop)0.8GB2GB1.5GB-4.3GB
After migration (Plan B)0.8GB0.3GB0.6GB0.3GB2.0GB
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.

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:

  1. Details tab → find telegram.exe (if still installed), discord.exe
  2. Memory column → check whether usage keeps increasing
  3. 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.

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
