Windsurf Rebrands as Devin Desktop and Launches Open Agent Client Protocol (ACP)
Cognition
Windsurf became Devin Desktop on June 2, bringing a unified Agent Command Center (Kanban), Spaces for cross-agent context sharing, and the open Agent Client Protocol (ACP) so third-party agents including Codex, Claude Code, and OpenCode can run inside the editor. Devin Local, a Rust-based rewrite of Cascade, offers 30% better token efficiency with subagent support. Legacy Cascade continues through July 1.
Why it matters
Open ACP protocol could standardize multi-agent IDE interoperability across competing coding agents, shifting the market toward a platform model.
