Cline

Cline is an open-source autonomous coding agent that runs as a VS Code extension. Unlike traditional coding assistants that provide suggestions, Cline executes complete workflows from a single natural language prompt. It can create and edit files, explore large projects, run terminal commands, and optionally use a browser to click elements, type text, and capture screenshots for interactive debugging and end-to-end testing. Every action requires your explicit permission, keeping you in control. It supports multiple model providers (including OpenRouter, Anthropic, OpenAI, and Google Gemini) plus local models through tools like Ollama.
