Windsurf
An AI-native code editor with an agent called Cascade that edits and runs code across your project.
What is Windsurf?
Windsurf is an AI-first code editor, originally created by Codeium. Its Cascade agent understands your codebase, makes multi-file changes, runs terminal commands and keeps track of your actions to suggest next steps. Cognition acquired Windsurf in 2025.
Windsurf is based on VS Code, so it feels familiar, but AI is built into every part of the editor.
Cascade can plan and carry out changes across many files, run commands and fix errors it encounters.
Features like previews and deployments help with web projects, and autocomplete speeds up typing.
Following Cognition's acquisition, Windsurf continues as a product alongside Cognition's Devin agent.
