Windsurf is a code editor that integrates Claude AI (via Codeium's API) to handle multi-file edits, debugging, and architectural decisions in a single continuous session. It competes directly with Cursor by offering similar agentic coding capabilities—letting the AI propose changes across your project rather than just completing one line at a time. The free tier includes limited monthly tokens; paid plans start around $10/month. The main friction point is rate limiting on the free tier, which can interrupt workflow for heavy users, and the closed pricing model makes it hard to predict enterprise costs.
