An open-source AI coding agent, written in Rust, with a native GUI, a terminal mode, and integrations for editors and MCP clients.
It runs an autonomous agent loop over your codebase — reading, searching, editing files, and running commands — while keeping you in the loop about what it is actually doing. The same binary serves as an MCP server (code-assistant server) and as an ACP agent for editors such as Zed (code-assistant acp).
