What is Windsurf AI, and what happened to it?

Windsurf was an AI code editor that Cognition acquired and renamed Devin Desktop in June 2026. What changed, what happened to Cascade, and what plans cost now.

Windsurf was an AI code editor, originally from Codeium, with an agent called Cascade. Cognition, the company behind Devin, acquired it in 2025 and renamed it Devin Desktop from 2 June 2026. Cascade reached end of life on 1 July 2026 and was replaced by Devin Local. Accounts and plans carried over to the new name.

The short history

  • Codeium built an AI autocomplete product and then the Windsurf editor, based on VS Code, with the Cascade agent.
  • In 2025, after a planned acquisition by OpenAI fell through and Google hired key staff, Cognition acquired Windsurf.
  • From 2 June 2026, Cognition retired the Windsurf brand and the editor became Devin Desktop, delivered as an update.
  • Cascade, the original agent, reached end of life on 1 July 2026, replaced by a new local agent called Devin Local.

What it means for Windsurf users

Reports on the change say accounts, plans, extensions and keybindings carried over automatically. Project rules needed migrating from the Windsurf rules folder to a .devin configuration folder. Rules not migrated before 1 July 2026 were no longer applied by the agent.

If an agent suddenly ignores your project conventions after the switch, check that your rules were moved to the .devin folder.

Current plans

Devin's pricing page on 9 November 2026 listed Free, Pro at 20 dollars a month, Max at 200 dollars a month, Teams at 80 dollars a month plus 40 dollars per developer seat, and Enterprise with custom pricing. Devin Desktop is included in the plans alongside Devin's cloud agent.

Alternatives

  • Cursor: the most similar AI editor built on VS Code.
  • VS Code with GitHub Copilot.
  • Terminal agents such as Claude Code and Codex, used alongside any editor.

What a scan can and cannot tell you

WebAuditOS checks the sites you build with any editor: security headers, console errors, duplicate titles and the other deployed basics.

It does not see your editor or agent configuration.

Changing tools mid-project is when conventions get lost. Scan before and after the switch to see whether anything regressed.

The checks this maps to

Every check named here runs on every scan, on every plan - what a plan changes is how many pages are crawled, how long the history is kept and what you can do with the result. These are the ids the findings carry, so you can match a line in a report to the explanation above.
