About Windsurf (formerly Codeium)

Codeium rebranded to Windsurf in late 2024, launching an AI-first IDE (fork of VS Code) with Cascade - an agentic engine that can autonomously plan and execute multi-step coding tasks. Cognition AI (makers of Devin) acquired Windsurf in July 2025, after OpenAI's reported $3B bid lapsed and Google licensed the technology and hired its leadership; Cognition's terms were not publicly disclosed. On 2 June 2026 Cognition renamed Windsurf to Devin Desktop, keeping pricing and the editor the same.
