Windsurf Cascade on JetBrains: agent gravity outside VS Code forks

What happened

Correction (verified 2026-10-06): Windsurf is now Devin Desktop; Cascade was replaced by Devin Local and the JetBrains plugin is in maintenance mode — see our updated Devin Desktop page. Cognition renamed Windsurf to Devin Desktop on 2 June 2026. Cascade was kept only through July, Cascade inside the JetBrains plugin is deprecated, and the vendor now recommends running Devin over ACP in JetBrains. Updated buyer card with current prices: /tools/windsurf.html (https://ai.126678.space/tools/windsurf.html). Original summary (2026-09-01, now outdated): What happened: Windsurf’s Cascade continues to be positioned as an agentic coding layer with Write/Chat modes, terminal execution levels (Off/Auto/Turbo), and JetBrains plugin gravity—not only a Cursor competitor in VS Code-land (verify current docs). Tool impact: teams refused to leave IntelliJ/PyCharm now have a credible “agent in my real IDE” story, which reframes Copilot ubiquity vs Cursor fork lock-in.

Switch or not?

Corrected 2026-10-06: don't pick Windsurf for Cascade-in-JetBrains any more — that plugin is in maintenance mode. JetBrains-native teams should test Devin over ACP or stay with their current agent; read the updated Devin Desktop page before buying seats.

Money / risk

Another agent seat beside Copilot/Cursor recreates the June metered-stack problem. Pick one primary agent surface per IDE family.
