Windsurf is Codeium's VSCode-fork IDE with the Cascade multi-file agent · acquired by Cognition AI in 2025 to pair with Devin.
Basic
Windsurf launched late 2024 from Codeium (the autocomplete company). The IDE is a VSCode fork with Cascade · an agent that reads the full repo and makes coordinated multi-file edits. Cognition acquired Codeium in 2025, integrating Windsurf into its Devin ecosystem. Post-acquisition, Windsurf became the IDE face of Cognition's agent stack.
Deep
Cascade pioneered "flow awareness" · the agent watches your recent actions (file opens, edits, terminal runs) and adjusts its plan without explicit prompting. This was distinct from Cursor's more reactive model. Pricing pre-acquisition was $15/month Pro; post-acquisition shifted to align with Cognition's Devin seats. Windsurf retains local IDE UX while Devin lives in the cloud · the pair positions Cognition as both local + remote agent provider.
Expert
Windsurf's "write mode" lets Cascade execute edits without approval; "chat mode" is conversational. The flow-awareness system indexes local changes in real-time to an internal graph, enabling the agent to reason over recent edits. Codeium's earlier autocomplete model (Codeium Chat) stayed available as a low-latency companion. Post-Cognition, Windsurf added Devin integration · handoff a task from local IDE to cloud VM seamlessly.
