What it does

FlClash is a Flutter‑based, cross‑platform client that lets you load a ClashMeta proxy configuration and route your device’s traffic through it.

When to use it
  • •You need a cheap, ad‑free way to run a Clash proxy on Android, iOS, macOS, Windows or Linux without buying a commercial app.
  • •Your team shares a single Clash config (Vmess, Trojan, etc.) and you want a UI to switch profiles and enable/disable the proxy quickly.
  • •You want to test a new ClashMeta configuration locally before deploying it to a production proxy server.
Ready-to-paste prompt
flutter run -d windows --dart-define=FLCLASH_DEFAULT_PROFILE=profiles/myconfig.yaml
Heads up: FlClash requires the device’s VPN/Proxy permission – on Android you must approve the “VPN service” dialog the first time you enable the proxy; without it the app will start but no traffic is routed.
