Frequently Asked Questions
5 questions
Cursor is a VS Code-based AI assistant emphasizing predictable control through Rules and Plan Mode, while Windsurf is Codeium's native agentic IDE prioritizing autonomous AI workflows. Windsurf leads in agent autonomy and enterprise scale (1M+ users, 59% Fortune 500), while Cursor excels in developer familiarity and deterministic behavior control.
Windsurf significantly outpaces Cursor with FedRAMP High, DoD IL5, and ITA certifications, making it the clear choice for government and highly regulated enterprise deployments. Cursor offers enterprise-grade security but lacks these specific high-security certifications.
Windsurf publicly reports 1M+ active users as of March 2026, with 70M+ lines of code generated daily and 59% Fortune 500 adoption. Cursor maintains significant enterprise adoption but does not publicly disclose specific user metrics.
Cursor is better for newcomers due to its familiar VS Code interface and intuitive autocomplete paradigm. Windsurf requires learning a new IDE paradigm but offers superior autonomous capabilities once the learning curve is mastered.
Cascade is Windsurf's agentic AI engine that enables autonomous planning and multi-step code workflows without explicit user direction. It powers features like Windsurf Tab for rapid multi-file edits and represents the core difference between Windsurf's agentic approach vs. Cursor's suggestion-based model.
