Windsurf is an AI native IDE built on VS Code that integrates its Cascade agent directly into the coding experience. Originally launched as Codeium (a free Copilot alternative), the product rebranded in late 2024 and shifted from autocomplete tooling to a full agentic IDE where the AI understands your entire codebase and can plan multi step edits across files.
Cascade is the core differentiator. It indexes your project through a proprietary system called Fast Context, building an understanding of your architecture and dependencies without requiring you to manually tag files or configure anything. The Memories feature learns your coding patterns over approximately 48 hours of active use, making suggestions progressively more accurate and aligned with your personal conventions. This creates a noticeably different experience from tools that treat every session as a blank slate.
In December 2025, Cognition AI (the company behind the autonomous coding agent Devin) acquired Windsurf for approximately $250 million. At the time, Windsurf had $82 million in ARR, over 350 enterprise customers, and a team of 210. Google secured a separate licensing deal for the underlying technology. As of March 2026, the two products remain largely separate, but the roadmap points toward merging Cascade IDE intelligence with Devin autonomous execution.
Pricing shifted in March 2026 from credits to a quota based system. Pro starts at $20 per month with access to SWE 1 (Windsurf proprietary models), Claude Sonnet, and GPT class models. Quota refreshes on daily and weekly cycles rather than monthly pools, which prevents burning your entire allocation in a single intensive session but also means you cannot sprint through complex work without hitting limits.
Windsurf ranked number one in the LogRocket AI Dev Tool Power Rankings as of February 2026, ahead of both Cursor and GitHub Copilot. For developers evaluating the category, it occupies a specific position: deeper automatic codebase context than Cursor, a strong beginner friendly reputation, and an uncertain but potentially transformative acquisition trajectory.
Key Features
Strengths & Limitations
- Deepest automatic codebase indexing — Fast Context indexes the entire project automatically before you ask anything, no manual file tagging required.
- Memories feature learns your coding patterns and conventions over ~48 hours of use, producing progressively more accurate suggestions.
- SOC 2 Type II with zero data retention defaults on Teams and Enterprise. FedRAMP High availability.
- Competitive pricing — Teams at $35/user is below Cursor Business at $40/user, a meaningful difference at team scale.
- Cognition AI acquisition in December 2025 creates product uncertainty — whether Windsurf remains standalone or merges into Devin is unresolved as of March 2026.
- Daily and weekly quota caps introduced in March 2026 can interrupt intensive sprint sessions mid-day.
- Smaller community than Cursor — fewer tutorials, guides, and community solutions to edge cases.
Who It’s For
Frequently Asked Questions
Yes. Codeium rebranded to Windsurf in late 2024. In December 2025, Cognition AI acquired Windsurf for approximately $250 million. The product continues under the Windsurf brand.
Both cost $20/mo for Pro. Windsurf has deeper automatic codebase context through Fast Context and Memories. Cursor has a larger community, parallel agents, BugBot, and Background Agents. Cursor is the safer bet for most developers. Windsurf is worth evaluating if adaptive context is your top priority.
Yes. Cognition AI (makers of Devin) acquired Windsurf for approximately $250 million in December 2025. Google secured a separate licensing deal for the underlying technology. As of March 2026 the products remain separate.
