CodeLite is a free, open source and cross-platform IDE for C, C++, Rust, PHP and Node.js. It runs on Linux, macOS, Windows and FreeBSD.
Fast, lightweight and built for developers who value speed, CodeLite gives you everything you need to write, build and debug your code: smart code completion, code navigation, a built-in debugger, Git integration and a rich plugin system.
Code smarter with AI. CodeLite works hand in hand with AI coding agents such as Claude Code and Kiro CLI. Classes, functions and files mentioned by the agent become clickable: one click opens them right in your editor, so you can follow the AI's work without ever leaving your IDE.
