Three years, three names. Codeium became Windsurf. Windsurf is now Devin Desktop.
On June 2, 2026, Cognition launched Devin Desktop — and the announcement signals something bigger than a rebrand. The AI code editor era is giving way to the AI agent management era.
From Code Completion to Agent Fleet Management
The history is worth tracing. Codeium started in 2022 as an AI autocomplete plugin: free, unlimited, supporting over 70 programming languages. It reached millions of downloads as one of the strongest GitHub Copilot alternatives. In 2024, the company raised a $150M Series C at a $1.25B valuation and launched Windsurf Editor — a VS Code fork positioning itself as an "AI-native developer workbench."
Then came the acquisition. After OpenAI reportedly offered $3B for Windsurf (a deal that fell through), Google hired away the founding team and core engineers. Cognition — the company behind the autonomous Devin AI engineer — acquired the remaining IP, product, brand, and enterprise customers. Windsurf continued operating under Cognition, deepening the integration between Devin's cloud agent and the local IDE.
Now the two products have fully merged into Devin Desktop.
The Agent Command Center
The defining feature of Devin Desktop is the Agent Command Center — a Kanban board that lets you manage multiple AI agents simultaneously from one surface.
Instead of context-switching between Cursor, ChatGPT, Claude, and your terminal, Devin Desktop becomes the single coordination layer. You dispatch tasks to local agents, cloud agents, or third-party agents, then monitor progress, review output, and intervene — all without leaving your editor.
Think of it as the difference between being a developer writing code and being a tech lead managing a team. The role of the engineer is shifting from writing every line to scoping, delegating, reviewing, and shipping. Devin Desktop is built for that second mode.
Spaces: Shared Context for Agent Teams
When you run multiple agents on the same codebase, context fragmentation becomes a real problem. One agent has no visibility into what another is doing. Devin Desktop solves this with Spaces — shared context containers that group sessions, pull requests, files, and relevant information so agents can collaborate rather than collide.
A Space acts like a shared workspace: any agent running inside it sees the same context. This is essential for complex tasks that span multiple parts of a codebase — one agent refactoring the API layer while another updates the tests, both aware of what the other is doing.
ACP: The Open Protocol for AI Coding Agents
The strategic bet in Devin Desktop is the Agent Client Protocol (ACP) — an open-source protocol that allows any compatible agent to run inside Devin Desktop alongside Devin. Think of ACP as the Language Server Protocol (LSP) equivalent for AI agents: a standard that decouples agents from editors.
At launch, Devin Desktop supports Codex, Claude Agent, OpenCode, and any custom in-house agents your team has built. The protocol is maintained by JetBrains and Zed, has over 3,300 GitHub stars, and is implemented in Rust.
The implication is significant. Cognition is not betting on having the best model — it is betting on owning the orchestration layer. Just as browsers became more valuable than search engines during the web wars, the agent management interface may end up more strategically valuable than any individual agent.
This is the same dynamic that made IDEs more powerful than compilers, and package managers more influential than any single library. The coordination layer captures the relationship with developers, regardless of which AI model is running underneath.
Devin Local: Rust-Powered, 30% More Efficient
Under the hood, the local agent has been completely rewritten. Devin Local replaces Cascade (the previous local agent) with a full Rust implementation that is up to 30% more token-efficient and adds native support for subagents.
Cascade remains available through July 1, 2026 for teams that need migration time. Devin Local maintains full compatibility with existing settings and capabilities, so the transition is seamless for most users.
The full Devin ecosystem now spans four surfaces:
- Devin Desktop — IDE plus agent management panel
- Devin Cloud — autonomous agents running in cloud VMs for long-horizon tasks
- Devin CLI — terminal-native agent access for command-line workflows
- Devin Review — automated code review triggered on every commit
What This Means for Developers
The shift Devin Desktop embodies is the most significant change in developer tooling since the introduction of language servers.
For solo developers, this means running multiple specialized agents in parallel: one agent for writing code, one for tests, one for documentation, one for reviewing PRs — all visible in a single Kanban view. Tasks that previously required manually switching context between four different tools now live in one surface.
For engineering teams, it means standardizing on one management interface without mandating a single AI model. Different agents can be better at different tasks. Teams at Ramp, Harvey, NVIDIA, Modal, and Intact Financial are already running this kind of multi-agent setup. Devin Desktop gives them the coordination layer without forcing a model choice.
The concern worth naming openly: when Devin Desktop runs Codex and Claude Agent as guests, Cognition sits between developers and AI providers. That is a powerful position. Whether ACP stays genuinely open or quietly becomes a lock-in mechanism is the question that will define whether this is good infrastructure or a sophisticated distribution play.
For now, the bet is on openness. Teams can build internal agents on the ACP standard, use competing cloud providers, and port to other ACP-compatible editors. But the user relationship belongs to whoever owns the desktop surface.
Migration from Windsurf
For existing Windsurf users, the transition is automatic. Updates arrive through the existing Windsurf update mechanism. Pricing stays the same, extensions carry over, keybindings are preserved, and configuration settings migrate without any manual steps.
There is no version number to track down and no reinstall required. Existing Windsurf users wake up to Devin Desktop.
Conclusion
Three years ago, Codeium autocompleted your code. Today, Devin Desktop orchestrates your agents. The jump from line-by-line completion to fleet-level management is not incremental — it is a different job description.
Whether Cognition's bet on the orchestration layer pays off will depend on how genuinely open ACP remains as commercial pressures increase. For now, the direction is clearly stated: the future of software engineering is agent management, and Devin Desktop is the first serious IDE built around that premise.
The rename is complete. Windsurf is gone. Devin Desktop is here.
