What Codebuff is
Codebuff is a paid, open-source AI coding agent that coordinates specialized sub-agents. It can write features, tests, and scripts; run command-line operations; adjust build configurations; review code; and answer repository questions. Codebuff parses source files into a tree of directories, files, and symbols so agents can locate code. It offers chat assistance, terminal access, codebase indexing, and support for VS Code and Cursor. Default, Max, Plan, and Lite modes can be switched during a session; Default and Max perform code review, while Plan does not write files. MCP servers can connect agents to services such as Notion and GitHub. Project instructions can come from knowledge.md, AGENTS.md, and CLAUDE.md. The @codebuff/sdk package enables programmatic use with an API key. Platforms include web, Windows, macOS, Linux, and API access. Plans start at $100 a month, with pay-as-you-go credits listed.
