Open source autonomous coding agent that runs inside your IDE
Cline is an open source AI coding agent that runs inside VS Code and compatible editors. It plans tasks, creates and edits files, runs terminal commands and can drive a browser to test web apps, asking for approval at each step unless you grant more autonomy. You bring your own API key for providers like Anthropic, OpenAI and Google or use local models, and MCP servers extend what it can do.
