Windsurf shuts Cascade and becomes Devin Desktop is a business and technology story about AI coding editors becoming agent command centers.
What changed
The core facts are: Cognition shut down Cascade on July 1 with no opt-out or extended support window; Windsurf was renamed Devin Desktop through an automatic update on June 2, preserving accounts, subscriptions, plugins and shortcuts; Devin Local was rewritten in Rust and is claimed to use up to 30% fewer tokens than Cascade; the interface centers on an Agent Command Center and supports ACP so Claude Agent, Codex and OpenCode can run in the editor.
Why it matters
The signal is that AI coding agents, ACP protocol support and editor strategy. The story is less about a single announcement than about how AI is moving into budgets, infrastructure, regulation and operating workflows.
What to watch
The next check is whether users accept the agent-first interface and whether ACP helps Cognition own the coding workspace rather than one model.
