Windsurf becomes Devin Desktop — Agent Command Center, open ACP protocol, and a Rust-rewritten Devin Local

On June 2, 2026, Cognition rebranded Windsurf as Devin Desktop — and with it, repositioned the product from a VS Code-fork AI code editor into a platform for running and orchestrating multiple AI coding agents at once. The rebrand ships four concrete product additions: Agent Command Center, Spaces, the Agent Client Protocol (ACP), and Devin Local.

Agent Command Center and Spaces. The Agent Command Center is the new centrepiece of Devin Desktop: a Kanban-style interface showing all running local and cloud agent sessions in one view, with their status, progress, and outputs. Spaces sit above individual sessions — they group related sessions with their pull requests, files, and shared context, so multiple agents can build on the same state rather than starting cold on each run.

Agent Client Protocol (ACP). The more architecturally significant announcement is the Agent Client Protocol — an open standard that lets any ACP-compatible agent run inside Devin Desktop with the same capabilities as Devin's native agents. At launch, the supported third-party agents are Codex, Claude Agent, and OpenCode; Cognition says custom in-house agents also work. The practical implication: if you want Codex to handle one file and Claude Agent another in parallel inside a single session with shared context, ACP is the primitive that makes that possible without writing custom orchestration code. Whether ACP gets adopted outside Devin Desktop will determine whether it becomes a durable interoperability standard or remains a Devin-specific integration layer.

Devin Local replaces Cascade. Devin Local is a complete Rust rewrite of the Cascade agent that shipped with Windsurf. Cognition states it delivers up to 30% greater token efficiency than Cascade and adds subagent support as part of the new Devin Local stack. For teams running Cascade-based workflows, the transition is mandatory: Cascade legacy support ends July 1, 2026. The performance and capability improvements are the incentive to move early; the deadline is the backstop.

What didn't change. Cognition's announcement is explicit on pricing: existing plan, pricing, extensions, and other features remain the same. Existing Windsurf and Devin subscribers get Devin Desktop at no additional cost.

For developers evaluating AI coding platforms. Devin Desktop now competes directly on agent orchestration with Cursor Background Agents, the GitHub Copilot App (which also launched on June 2 at Microsoft Build), and the terminal-native approach of Claude Code. The differentiator Cognition is betting on is ACP — the idea that you don't have to commit to one coding agent because multiple agents can share a workspace natively.
