Cline

Cline is an open-source agentic coding assistant that ships as a VS Code extension. It brings a plan-and-act loop directly into the editor and aims at autonomous task completion through tools like file read/write, terminal execution, and browser use. Compatibility with Claude Sonnet, Llama 3, and other models keeps it flexible across cloud and local setups. Alongside Cursor and Continue it is one of the main Coding Agents anchors inside the VS Code ecosystem.
