Cursor vs Windsurf (Devin Desktop)
The two agent-first IDEs score identically — so what actually separates them? Scores from the RXed AI Periodic Table v1.0 — identical 20-element scale, deterministic overall. How we audit →
The verdict
Both land at 7.5/10 across 17 elements, and both score Ag 9 — these are the two most agent-forward IDEs money can buy. The separation is in the fine print. Cursor edges ahead on raw model surface (Lg 9 vs 8.5, Pr 8 vs 7.5) and ships the larger ecosystem, but its sticker price is a floor on a usage meter and its next owner is SpaceX/xAI, with the deal closing Q3 2026. Windsurf — renamed Devin Desktop — counters with real enterprise compliance (FedRAMP/HIPAA/ITAR) and JetBrains support, at the cost of betting on Cognition's Devin-first roadmap after two owners and two renames in a year. Regulated environment → Windsurf. Everyone else managing their own credit burn → Cursor, eyes open on the acquisition.
