EchOS-Win —— ECH Encrypted Proxy Client for Windows

ECH + TLS1.3 (Encrypted Client Hello) tunnel proxy client for Flutter / Windows only.
Local traffic routing (bypass mainland China / blacklist / global + custom rules), direct connection via a simple WebSocket protocol, TLS session reuse, and automatic retries across multiple entry points.

:speech_balloon: Rewritten in Flutter as a Windows client based on everyone’s needs. Feedback is welcome~

Highlights

  • ECH anti-DPI: TLS ECH encryption combined with Cloudflare Workers makes it more stealthy than traditional proxies
  • Free server: Deploy with one line on Cloudflare Worker; the free plan allows 100,000 requests per day
  • No additional tools required: Local SOCKS5 + HTTP dual-protocol proxy, with one-click system proxy takeover/automatic restoration
  • Three routing modes: Bypass mainland China / blacklist / global, with support for custom geosite / geoip rules
  • Multiple servers + sharing + backup: Export, import, and share servers; back up the entire configuration locally / via WebDAV
  • Launch at startup and taskbar display: Customizable taskbar icon, with a redesigned and optimized tray menu for a better user experience
  • Connectivity self-check: Pre-check the configuration before starting; check the port, direct connection, and tunnel with one click while running
  • Installer / portable version: Supports automatic update checks, one-click download, replacement, and restart, with no leftovers in the uninstallation directory

Note:

If the server cannot be used,
change the “Compatibility Date” to any date before 2026. Based on user feedback from April 2026, deployment and use are not working.

This is an open-source project, and my abilities are limited~
Once again, thanks to everyone who has shown interest and to all the open-source experts.

Now I can use it without reinstalling macOS.

Is the traffic routed through Cloudflare?
If I set up a Worker, will my Cloudflare account get suspended?

In theory, it shouldn’t, but there’s no guarantee. For details, see the source cited in the other post.

I suggest adding an ALT+TAB shortcut to switch to your Ech software. It isn’t available at the moment.

Right-click the tray icon: Show the icon in the taskbar

The enthusiasm wore off, so I stopped messing with this thing.
