In Depth
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 even launch 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. With 5M+ installs and 60K+ GitHub stars, it is one of the most popular AI coding extensions available. It supports any model provider including OpenRouter, Anthropic, OpenAI, Google Gemini, Cerebras, Groq, and local models through LM Studio or Ollama.
Windsurf
Windsurf is an AI-native IDE from Codeium, built as a direct competitor to Cursor. Its standout feature is Cascade - an agentic mode that reads your codebase, plans changes across multiple files, and executes them step by step with a diff preview. It supports Claude, GPT, and Codeium's own models. The free tier is more generous than Cursor's, making it accessible for individual developers. Windsurf excels at multi-file refactors and has strong context awareness across large codebases. It's VS Code-compatible, so extensions and keybindings carry over seamlessly.
