Which one should you pick?
Cline and Windsurf both compete against Cursor but in opposite ways. Windsurf competes head-on with the same product shape — a forked IDE with an agent and tab autocomplete, just at a lower price point ($15 vs $20/mo Pro).
Cline competes by being free and open source. It runs as a regular VS Code extension, not a fork, and uses whatever LLM API key you bring. For developers comfortable managing their own API keys, this is significantly cheaper for heavy use — and you keep your existing VS Code setup untouched.
