Windsurf
AI-native IDE with strong agentic capabilities via Cascade agent and persistent memory across sessions.
A polished AI-native IDE with strong agentic capabilities via Cascade, but corporate uncertainty (Cognition acquisition) introduces risk for long-term adoption.
Windsurf (formerly Codeium) was acquired by Cognition AI for $250M in 2025, and Google later licensed the technology for $2.4B to build Antigravity. That deal puts Windsurf's technology inside two products, but the corporate story introduces uncertainty, the OpenAI bid for Windsurf collapsed, and several key engineers left for Google.
The product itself is strong: the Cascade agent provides persistent memory across sessions (a feature Cursor lacks), and it ranked #1 in the LogRocket AI Dev Tool Power Rankings (February 2026). The proprietary SWE-1/1.5 models are optimised specifically for coding tasks. At $20/mo (raised from $15 in March 2026), it matches Cursor's pricing but lost the budget advantage that initially differentiated it.
For developers evaluating Windsurf today, the question is less about features and more about trajectory. The Cognition/Devin integration roadmap could create a unique IDE+autonomous agent pipeline, or the corporate complexity could slow development. Persistent memory is a genuine differentiator, if stability matters more than cutting-edge, Windsurf delivers.
