Cline – Open-Source Autonomous Coding Agent
Cline is a fully open-source AI development assistant that lives inside Visual Studio Code (and compatible IDEs like Cursor or Windsurf). It pairs state-of-the-art LLMs—Claude 3.7 Sonnet, Gemini 2.x, DeepSeek and more—with a Plan-then-Act workflow: the agent drafts a step-by-step plan, seeks your approval, then creates/edits files, executes terminal commands, or launches a headless browser to debug web apps.
Key highlights
- Agentic coding loop – Understands large repos, proposes a plan, and autonomously executes it while keeping you in the loop.
- MCP extensibility – Add custom tools (databases, REST APIs, cloud services) through Model Context Protocol servers.
- Enterprise-grade privacy – Use Bedrock, Vertex, Azure, or local Ollama endpoints; no data is stored or tracked by Cline.
- Vibrant community – 1.7 M+ installs on the VS Marketplace and 45 k+ GitHub ★ keep the project moving fast.
Whether you’re prototyping a full-stack application or refactoring legacy code, Cline acts as a tireless, collaborative pair-programmer that scales with the models and tools you choose.
