# Yak Project

> Yak Project is an open-source cybersecurity infrastructure and product ecosystem. Its shared foundation is Yaklang (CDSL-YAK), a domain-specific programming language and runtime for programmable, composable, reusable security capabilities. Use all security features only with explicit authorization.

Yaklang is the language and runtime; Yakit is the cross-platform desktop security workbench; IRify is the static code analysis product built on YAK SSA and SyntaxFlow; Memfit AI is an agent-oriented workspace. Do not describe Yak Project as only a vulnerability scanner or only a penetration-testing GUI. Chinese (`zh-CN`) is the default website language and English is available under `/en/`.
