About Windsurf

Windsurf was one of the first agentic IDEs — a VS Code-based editor with two flagship AI features: Tab for code completion and Cascade for multi-step, multi-file code edits. Its deep Anthropic Claude integration gave it strong reasoning for complex refactors, and its agentic workflow let developers describe a goal and let the IDE plan and execute the changes. Windsurf reached $82M ARR and served 350+ enterprise customers, with Google reportedly attempting a $2.4B acquisition before Cognition Labs closed the deal on July 14, 2025. Post-acquisition, Windsurf's IP and team are being integrated into the Devin ecosystem — meaning the product as a standalone IDE is in active transition. Existing features remain functional, but the long-term roadmap is now Cognition's.

Verdict

Windsurf was a strong agentic IDE with one of the best multi-step editing workflows available. However, its acquisition by Cognition Labs in July 2025 fundamentally changes the calculus — it is no longer an independently developed product, and its capabilities are being folded into Devin. Existing users can continue using it, but new users should look at Devin or Cursor instead. This is an entry in transition, not a product with its own long-term roadmap.

Pros & Cons

Pros

Cascade was one of the best multi-step agentic editing workflows in any IDE
Deep Claude integration gave strong reasoning for complex refactors
VS Code foundation meant familiar extension ecosystem
Proven at enterprise scale — 350+ customers and $82M ARR at acquisition

Cons

Acquired by Cognition Labs July 2025 — no longer an independent product
Long-term standalone roadmap is uncertain; IP is being absorbed into Devin
Pricing and feature direction are now controlled by Cognition, not Codeium
New users should evaluate Devin directly rather than investing in Windsurf separately

Frequently Asked Questions

What happened to Windsurf?

Cognition Labs (makers of Devin) acquired Windsurf from Codeium on July 14, 2025. The product is being integrated into Cognition's Devin ecosystem. It remains functional but its future as a standalone IDE is uncertain.

Should I still use Windsurf?

If you are already using it, it continues to work. For new adopters, consider evaluating Devin directly — Cognition's focus and development investment is now on integrating Windsurf's capabilities into the broader Devin platform rather than maintaining a separate IDE.

How does Windsurf compare to Cursor?

Both are VS Code-based agentic IDEs with strong AI editing. Cursor has broader market momentum and independent development. Windsurf's Cascade workflow was comparable to Cursor's Composer, but post-acquisition, Cursor is the safer long-term bet for a standalone IDE.
