Cline

Cline is an open-source autonomous coding agent built as a VS Code extension, released under Apache 2.0 by Cline Bot Inc. It operates directly inside your editor, combining LLM reasoning with full access to your file system, terminal, browser, and MCP tools to complete complex software engineering tasks end-to-end — from feature implementation to debugging to PR creation.

Key features

• VS Code native: runs inside your editor, reads/writes files, executes terminal commands
• Multi-step task execution: plan → implement → test → debug, all in one session
• Any LLM: Claude, GPT-4, Gemini, local Ollama models — configurable in settings
• Built-in browser tool for live web research and testing
• MCP tool support — connect to any MCP server from within your agent session
• Transparent: shows every planned action for human approval before execution
• Apache-2.0 license

Quick start

1. Install "Cline" from VS Code Marketplace
2. Configure your LLM API key (Anthropic / OpenAI / etc.) in settings
3. Open a project folder in VS Code
4. Open Cline (Ctrl/Cmd + Shift + P → "Cline: Open")
5. Type your task:
   "Add a dark mode toggle to this React app. Update the CSS, add a context provider, and write a Vitest test."
6. Cline will plan the changes, show them to you, and execute on approval.
