Windsurf
CodeiumAI-native IDE (VS Code fork) with 'Cascade', an agentic flow engine that maintains context across multi-step coding tasks, automatically suggests and executes terminal commands, file edits, and debugging steps. Differentiates through 'Flows' that blend co-pilot suggestions with autonomous agent actions, plus strong context awareness across large codebases. Reportedly millions of users across free and paid tiers; Codeium raised $150M at a $1.25B valuation before being acquired by Windsurf (the brand name superseded Codeium).
Windsurf (formerly Codeium) acquired by Cognition (def. agreement July 2025) and rebranded 'Devin Desktop' on June 2 2026; windsurf.com redirects to devin.ai/desktop. Agent manager wrapped in a full IDE; Cascade legacy, successor Devin Local (Rust). Verified June 2026.
