About Windsurf (Codeium)

Windsurf is the AI code editor formerly known as Codeium, now owned by Cognition (the Devin team) — bringing the SWE-1.5 proprietary model that runs 13x faster than Sonnet 4.5 and engineering depth to a polished IDE. Cascade is the autonomous agent that plans + executes multi-step actions, Codemaps provide AI-annotated visual code navigation (unique to Windsurf), and Memories let Cascade remember codebase + workflow patterns across sessions. Free (25 credits/mo), Pro $20/mo (raised from $15 in March 2026), Teams $30/user, Enterprise $60/user. Plugins for 40+ IDEs.
