An open-source AI coding agent that runs in the terminal. It provides two built-in agents to assist with writing and analyzing code. The build agent has full access for development tasks, while the plan agent refuses file edits and explores the codebase in read-only mode.

You can instantly switch between agents using the Tab key to select the mode that fits your task context. The plan mode supports safe exploration, such as asking for permission before executing bash commands. For complex searches or multi-step tasks, you can invoke the @general sub-agent.

It supports macOS, Windows, and Linux, and also offers a beta version of the desktop app. With documentation available in 19 languages, it has an active global developer community. It is released under the MIT license, allowing for free use and modification.
