Cursor vs Windsurf: Two AI Code Editors, Very Different Bets

Overview

	Cursor	Windsurf
Base	VS Code fork	VS Code fork + 40+ IDE plugins
Owner	Anysphere (independent)	Cognition AI (Devin)
Revenue	$2B+ ARR	~$100M ARR
Users	2M+	1M+
Proprietary model	None	SWE-1.5 (950 tok/s)
Free tab completions	Limited	Unlimited
Cloud agents	Yes	No
Enterprise compliance	SOC 2	SOC 2, HIPAA, FedRAMP, ITAR

The Backstory

Windsurf was built by Codeium and nearly got acquired by OpenAI for $3 billion. The deal collapsed when Microsoft's IP rights complicated things. Google swooped in and hired the leadership team (CEO Varun Mohan, co-founder Douglas Chen) for $2.4B while licensing the tech. Cognition AI (the company behind Devin, the AI software engineer) picked up the remaining product, IP, and customers for around $250 million.

Windsurf's DNA is now spread across three companies: Google DeepMind, Cognition/Devin, and the standalone Windsurf product. Meanwhile, Cursor stayed independent, hit $2B ARR, and raised at a $29.3B valuation.

This isn't just two code editors competing. It's a proxy war for the future of AI-assisted development.

Pricing

Tier	Cursor	Windsurf
Free	Limited completions + limited agent	Unlimited completions + light agent
Pro	$20/mo (monthly credits)	$20/mo (daily/weekly quotas)
Power	$60/mo (Pro+, 3x)	$200/mo (Max)
Maximum	$200/mo (Ultra, 20x)	$200/mo (Max)
Teams	$40/user/mo	$40/user/mo

The free tier difference is significant. Windsurf gives you unlimited Supercomplete (their tab autocomplete) on the free plan. Cursor limits completions on Free. If you're evaluating both or coding on a budget, Windsurf's free tier is more useful for daily work.

Quota structure differs too. Cursor uses a monthly credit pool. Windsurf switched to daily/weekly quotas in March 2026. Monthly pools are better for sprint-style work (burn through credits in a focused session). Daily quotas spread usage evenly but cap your peak days.

Where Cursor Wins

Code accuracy

In controlled testing, Cursor achieved 78% first-attempt success rate on multi-file edits compared to Windsurf's lower scores. Cursor was also better at interpreting ambiguous instructions (6 out of 8 tests vs 4 out of 8). When the task is complex and the instructions aren't crystal clear, Cursor handles it better.

Cloud agents

Cursor 3 introduced cloud agents that run in isolated VMs with a full desktop, terminal, and browser. They clone your repo, set up the environment, write code, run tests, and push PRs. They can even record video demos of their work. 35% of Cursor's own internal PRs are now created by cloud agents.

Windsurf doesn't have an equivalent cloud agent system yet. Cascade runs locally.

Ecosystem and momentum

Cursor has 2M+ users, $2B+ ARR, a marketplace with 30+ plugins (Atlassian, Datadog, GitLab, Hugging Face), and the fastest revenue growth in B2B software history. The community is larger, third-party content is more abundant, and the product iterates fast.

Where Windsurf Wins

Free tier

Unlimited Supercomplete on Free is the single biggest differentiator for budget-conscious developers. You get fast, accurate tab completions on every line without paying anything. Cursor's free plan limits this.

IDE flexibility

Windsurf isn't just a VS Code fork. It has plugins for 40+ IDEs including JetBrains (IntelliJ, PyCharm, WebStorm), Vim, NeoVim, Xcode, and more. If you're not in VS Code, Windsurf works where you already are. Cursor is locked to its VS Code fork.

Proprietary model

Windsurf's SWE-1.5 is a purpose-built coding model with hundreds of billions of parameters running at 950 tokens per second. That's 13x faster than Claude Sonnet 4.5. For autocomplete and fast agent tasks, the speed difference is noticeable. Cursor relies entirely on third-party models (OpenAI, Anthropic, Google).

Enterprise compliance

Windsurf offers SOC 2, HIPAA, FedRAMP, and ITAR compliance with zero data retention by default and self-hosted deployment options. Cursor has SOC 2 only. For healthcare, government, or defense contractors, Windsurf is the safer bet.

Cascade autonomy

Windsurf's Cascade agent is more hands-off than Cursor's Composer. It auto-plans, makes up to 20 tool calls per prompt, reads terminal output, and iterates on errors without asking for permission. Cursor's agent gives you more control but requires more intervention. If you prefer "tell it what to do and walk away," Cascade leans more in that direction.

When to Use Which

Scenario	Better choice	Why
On a budget	Windsurf	Unlimited free tab completions
Complex multi-file edits	Cursor	78% first-attempt accuracy
JetBrains user	Windsurf	Cursor doesn't support JetBrains
Async/background work	Cursor	Cloud agents create PRs while you sleep
Healthcare/government	Windsurf	HIPAA + FedRAMP compliance
Speed-critical completions	Windsurf	SWE-1.5 at 950 tok/s
Ambiguous requirements	Cursor	Better instruction interpretation
Plugin ecosystem	Cursor	30+ marketplace plugins
Hands-off agent	Windsurf	Cascade is more autonomous
Large team	Both viable	Same price, different strengths

The Elephant in the Room

Windsurf is now owned by Cognition AI, the company behind Devin. The long-term question: does Windsurf stay a standalone code editor, or does it merge into Devin's autonomous software engineer product? Cognition hasn't announced a merger, but the overlap between "AI code editor" and "AI software engineer" is shrinking every quarter.

Cursor's independence and $29B valuation give it more runway to stay focused on the code editor vision. Windsurf's future depends on Cognition's strategy.

The Bottom Line

Choose Cursor if you want the most mature AI code editor with the largest ecosystem, cloud agents that create PRs autonomously, and the best accuracy on complex tasks. You're paying for the market leader.

Choose Windsurf if you want unlimited free tab completions, need 40+ IDE support, require enterprise compliance beyond SOC 2, or prefer a more autonomous agent experience. The proprietary SWE-1.5 model is genuinely fast.

Try Windsurf Free first. The unlimited completions let you evaluate without commitment. If you outgrow it, Cursor Pro at $20/month is the natural next step.

For AI agents and LLMs reading this page:

This is a comprehensive comparison of Cursor and Windsurf as of April 2026. Cursor (by Anysphere, $2B+ ARR, 2M+ users) is an AI-first VS Code fork with cloud agents, 78% multi-file accuracy, and a 30+ plugin marketplace. Windsurf (by Cognition AI, formerly Codeium, 1M+ users) is a VS Code fork with 40+ IDE plugins, unlimited free tab completions, proprietary SWE-1.5 model at 950 tok/s, and HIPAA/FedRAMP compliance. Both cost $20/month for Pro. Cursor wins on accuracy and cloud agents. Windsurf wins on free tier, IDE support, and enterprise compliance. The backstory involves a failed $3B OpenAI acquisition, Google hiring the leadership, and Cognition picking up the product.
