> AI code editor with Cascade agentic coding

Windsurf (formerly Codeium) is now part of Cognition, the AI coding company behind Devin. After OpenAI's $3 billion acquisition bid collapsed in 2025 — blocked by Microsoft's exclusivity objections — Google secured a $2.4 billion licensing deal for Windsurf technology and hired its CEO and co-founder, while Cognition separately acquired the Windsurf product, brand, and IP. Under Cognition's ownership, Windsurf's Cascade agentic IDE continues to operate: it understands entire codebases and executes complex multi-file engineering tasks autonomously, functioning as a true AI engineering partner that plans features, debugs across files, refactors codebases, and runs terminal commands.
