Windsurf
Windsurf by Codeium is an AI-first code editor with Cascade, an agent that reads your whole codebase, edits multiple files and runs terminal commands autonomously. Its free tier is far more generous than GitHub Copilot — making it the most popular free Copilot alternative in 2025. Compared to Cursor, Windsurf costs less for similar multi-file editing capability.

Is Windsurf really free, or does it have hidden limits?
Its free tier is genuinely more generous than most competitors, though heavier or team usage will eventually benefit from a paid plan — check current limits before assuming unlimited use.
