- Local HTTP/HTTPS/SOCKS server with authentication support
- Shadowsocks(R), VMess, VLESS, Trojan, Snell, WireGuard, SOCKS5, HTTP(S) outbound support
- Built-in fake-ip DNS server that aims to minimize DNS pollution attack impact. DoH/DoT upstream supported.
- Rules based off dynamic scripting, domains, GEOIP, GEOSITE, IP-CIDR or process names to route packets to different destinations
- Proxy groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select proxy based off latency
- Remote providers, allowing users to get proxy lists remotely instead of hardcoding in config
- Transparent proxy: Redirect TCP and TProxy TCP/UDP with automatic route table/rule management
- Hot-reload via the comprehensive HTTP RESTful API controller
- System/gVisor stack TUN device on macOS, Linux and Windows
- Policy routing with Scripts

A root CA certificate is required, the MITM proxy server will generate a CA certificate file and a CA private key file in your Clash home directory, you can use your own certificate replace it.
Need to install and trust the CA certificate on the client device, open this URL https://mitm.clash/cert.crt by the web browser to install the CA certificate, the host name 'mitm.clash' was always been hijacked.
NOTE: this feature cannot work on tls pinning

It's recommended to use fake-ip mode for the DNS server.
Clash needs elevated permission to create TUN device:
$ sudo ./clash
Then manually create the default route and DNS server. If your device already has some TUN device, Clash TUN might not work. In this case, fake-ip-filter may helpful.
Enjoy! :)
