AI Tool Comparison
Cline vs Windsurf
A side-by-side breakdown to help you pick the right tool for your workflow.
Cline
Run an AI coding agent inside your editor that reads and edits files, runs terminal commands, and executes multi-step development tasks with human approval at each step. Open source with 4.5M+ installs.
Windsurf
An agentic coding IDE pairing an editor with autonomous coding agents, renamed Devin Desktop after Cognition AI's acquisition, keeping the same editor and Claude/GPT/Gemini model choice.
Bottom Line
Last reviewed: August 2026
Cline and Windsurf both sit in Coding, but they're built around different use cases within it. Cline runs on a fully free plan while Windsurf runs on a freemium model, which alone may settle it if budget or a free tier is a hard requirement. Both carry the same 4.7 rating, so the decision comes down to fit, not quality.
Choose Cline if…
Best for developers who want an autonomous coding agent in VS Code that can actually complete multi-step tasks, and its edge is human approval checkpoints on each consequential action, not a black box running unsupervised in your codebase. Genuinely autonomous and open-source, API costs can climb fast on complex tasks so watch usage.
Choose Windsurf if…
Best for developers who want an AI agent that actively works across multiple files, not just suggests the next line, and its edge is cascade operates as a persistent coding agent that plans steps, writes across files, and runs terminal commands. A genuinely capable autonomous agent, still newer software, expect occasional instability on complex tasks.
