About Cline

Cline is an open-source autonomous coding agent that integrates directly into VS Code and Cursor. Unlike traditional AI assistants, Cline operates as a full development agent — it can read your entire codebase, create new files, run terminal commands, edit code across multiple files, and even deploy your application. Built on a plugin architecture, Cline supports multiple LLM backends including Claude, GPT-4, and local models. It's particularly popular among developers who want an AI pair programmer that can actually execute changes rather than just suggesting code.
