windsurf is now devin desktop — and cascade is already dead
Cognition quietly rebranded Windsurf to Devin Desktop via an OTA update in June. Cascade reached end-of-life on July 1. Devin Local, its Rust-based replacement, is 30% more token-efficient and supports sub-agents. if you have Windsurf installed, you're already running Devin Desktop.
If you still have Windsurf installed and haven't looked at it in a few weeks, open it. You'll find it's been renamed. On June 2, 2026, Cognition pushed a standard over-the-air update to every Windsurf install and the product came up as Devin Desktop. No reinstall. No migration wizard. Your extensions, keybindings, account, and MCP connections all carried over.
The path to this rebrand is convoluted: OpenAI's reported acquisition of Windsurf collapsed in July 2025. Google then hired Windsurf's founders in a $2.4 billion licensing deal, and Cognition — the company behind the Devin autonomous coding agent — acquired the product itself. The new name reflects that full merger: Windsurf's editor shell is now the desktop surface for Cognition's Devin agents.
cascade is gone
Cascade, the agent that drove Windsurf's inline completions and multi-file edits, reached end-of-life on July 1, 2026. Cognition's documentation stated it was available “through July 1st” — past tense now. Any CI pipeline, automation script, or workflow rule that explicitly invoked Cascade by name needs to be updated.
The replacement is Devin Local. It's a complete Rust rewrite of Cascade's core — not a renamed version, not a wrapper. Cognition claims it is up to 30% more token-efficient than Cascade was. The other material difference: Devin Local supports sub-agents. A single local session can spawn parallel helper agents for subtasks, which is something Cascade never did natively.
the ACP layer is the more interesting story
Devin Desktop ships with support for the Agent Client Protocol (ACP) — an open protocol released under Apache 2.0. ACP is what lets Codex, Claude Agent, Gemini CLI, OpenCode, and others run as first-class agents inside the same editor. Instead of each tool demanding its own IDE surface, they all become selectable agents in Devin Desktop's Agent Command Center.
whether that actually works in practice depends on how stable the ACP spec turns out to be, and how quickly other toolmakers ship compliant connectors. but the architecture is sound: one editor shell, many swappable agents. if it holds, it's a better answer to IDE fragmentation than everyone running three editors in parallel.
pricing changed
Windsurf's old Pro plan was $15/month. The new Devin Desktop Pro plan is $20/month — the same price as Cursor Pro. Cognition added a Max tier alongside the rebrand. Prior to the OTA, billing was credits-based; Cognition moved to daily and weekly quotas in March 2026, so if you already switched then, the rebrand didn't change your billing model.
what to actually do
If you were a Windsurf user:
- you're already on Devin Desktop — nothing to install
- if you had scripts or CI steps referencing Cascade, repoint them to Devin Local before they break on next run
- check your plan if you were on the $15 Pro tier — you may have been auto-migrated to $20
If you were on Cursor or a different editor and are evaluating options: Devin Desktop's ACP support is a genuine differentiator, but the ecosystem of compliant agents is still thin. it's worth watching in Q3 2026 to see how many tools actually ship ACP connectors.
