Cline
An open-source collaborative coding agent that runs locally as an editor extension and a CLI, planning before acting and letting teams bring their own model keys.
Cline is an open-source coding agent running as an editor extension and a CLI, keeping code local by default. It splits work into Plan and Act stages: reading the codebase and requirements first, then editing files, running commands and verifying results, with every change reviewable before it lands. Rules and memory hold team conventions, and native MCP support connects databases, APIs and documents as tools.
