What is Windsurf?
Windsurf is an AI-powered code editor that reimagines coding through developer-AI collaboration. Originally launched as Codeium’s autocomplete extension, it evolved into a full standalone IDE with the Cascade feature—an agentic system with deep contextual awareness.
What truly differentiates Windsurf in 2026 is its generous free tier. While competitors limit free users to a few dozen requests, Windsurf offers unlimited autocomplete and meaningful access to Cascade features without payment. This makes it the best option for evaluating AI coding tools before committing to a subscription.
Windsurf’s Cascade feature enables multi-file editing, codebase understanding, and autonomous task execution—capabilities that rival paid tools like Cursor’s Composer.

FAQ
Is Windsurf completely free? The free tier is genuinely usable with unlimited autocomplete. Cascade (the agentic feature) has daily limits on free tier but is still functional.
Should I use the IDE or VS Code extension? The standalone Windsurf IDE offers the best experience with full Cascade integration. The VS Code extension provides autocomplete but fewer agentic features.
How does Windsurf compare to Cursor? Both offer similar capabilities. Windsurf has a better free tier; Cursor has a larger community and more mature features. Try both—they’re both free to start.
What happened to Codeium? Codeium rebranded to Windsurf in late 2024. The company and technology are the same; the brand reflects the evolution from autocomplete to full IDE.
