Cognition Retires Windsurf, Relaunches as Devin Desktop with Open Agent Client Protocol

Devin Docs·high signal

On June 2, 2026, Cognition pushed an OTA update that reopened Windsurf as Devin Desktop — repositioning the IDE as an 'agent manager' rather than an editor with AI bolted on. It ships Devin Local (a Rust rewrite of Cascade, ~30% more token-efficient, with subagents; Cascade deprecated July 1) and adds the Agent Client Protocol (ACP), letting Claude Agent, Codex, OpenCode and 25+ ACP-compatible agents run natively in the same Kanban view and share context via Spaces. Plans and pricing are unchanged.
