What is Clash?
Welcome to the official knowledge base of the Clash core project ("Clash").
Clash is a cross-platform rule-based proxy utility that runs on the network and application layer, supporting various proxy and anti-censorship protocols out-of-the-box.
It has been adopted widely by the Internet users in some countries and regions where the Internet is heavily censored or blocked. Either way, Clash can be used by anyone who wants to improve their Internet experience.
There are currently two editions of Clash:
- Clash: the open-source version released at github.com/Dreamacro/clash
- Clash Premium: proprietary core with TUN support and more (free of charge)
While this wiki covers both, however, the use of Clash could be challenging for the average users. Those might want to consider using a GUI client instead, and we do have some recommendations:
- Inbound: HTTP, HTTPS, SOCKS5 server, TUN device*
- Outbound: Shadowsocks(R), VMess, Trojan, Snell, SOCKS5, HTTP(S), Wireguard*
- Rule-based Routing: dynamic scripting, domain, IP addresses, process name and more*
- Fake-IP DNS: minimises impact on DNS pollution and improves network performance
- Transparent Proxy: Redirect TCP and TProxy TCP/UDP with automatic route table/rule management*
- Proxy Groups: automatic fallback, load balancing or latency testing
- Remote Providers: load remote proxy lists dynamically
- RESTful API: update configuration in-place via a comprehensive API
*: Only available in the free-of-charge Premium edition.
