Windsurf was an AI-native code editor IDE (fork of Visual Studio Code) featuring the agentic assistant "Cascade," originally released by Codeium in November 2024. The company was later renamed to "Windsurf" and partially acquired by OpenAI/Cognition AI in 2025; since 2026, the product operates under Cognition AI (maker of "Devin") under the new name "Devin Desktop," with functionality, subscriptions, and settings automatically carried over. Pricing currently ranges from Free to Pro ($15–20/month) or Max ($200/month) with a quota-based usage model for the Cascade AI agent, while basic tab autocompletion remains unlimited across all plans. As its base model, Windsurf/Devin Desktop relies on the proprietary SWE-1-Mode
