What Is Cursor?
Cursor is the AI code editor that started the “AI-first VS Code fork” category. Built by Anysphere and launched publicly in 2023, it replaced the traditional extension model with an editor where AI is a first-class citizen. Its flagship Composer feature lets you describe a change in plain language and have the AI plan and execute edits across your entire codebase.
Cursor Pro lets you switch between AI models — Claude 3.7 Sonnet for reasoning-heavy tasks, GPT-4o for speed-sensitive ones. This flexibility is a meaningful differentiator.
Cursor Key Features
- Tab autocomplete with next-edit prediction — anticipates your next change, not just next token
- Cmd+K inline edit — select + describe → in-place rewrite
- Composer — multi-file agentic editing with step-by-step change preview
- Codebase indexing — full project context available in every interaction
- Model switching — Claude 3.7, GPT-4o, and others per request
Cursor Pricing
| Plan | Price | Notes |
|---|---|---|
| Hobby | Free | 2,000 completions/mo, limited models |
| Pro | $20/mo | Unlimited, Claude 3.7, GPT-4o |
| Business | $40/user/mo | SSO, admin, privacy enforcement |
What Is Windsurf?
Windsurf is Codeium’s AI code editor, launched in late 2024. Codeium was known for its free AI autocomplete extension before pivoting to an editor that competes directly with Cursor. The key differentiator Codeium brought is Cascade — their answer to Composer — plus a more generous free tier powered by their proprietary models.
Windsurf has grown quickly and earned genuine praise from developers who find Cursor’s $20/month Pro tier hard to justify for lighter workflows.
Windsurf Key Features
- Tab autocomplete — powered by Codeium’s base model (free, unlimited)
- Cmd+I inline edit — equivalent to Cursor’s Cmd+K
- Cascade — multi-step agentic editing across files, with terminal command execution
- Codebase awareness — similar indexing to Cursor, slightly smaller context window
- Flows — automation sequences combining file edits with shell commands
Windsurf Pricing
| Plan | Price | Notes |
|---|---|---|
| Free | $0 | Unlimited Codeium base completions, 5 Cascade uses/day |
| Pro | $15/mo | Unlimited Cascade, GPT-4o access |
| Teams | $35/user/mo | Admin, SSO |
Feature-by-Feature Comparison
Tab Autocomplete: Draw
Both tools offer strong autocomplete. Cursor’s “next-edit prediction” is marginally better at anticipating refactor patterns mid-flight. Windsurf’s free tier completions (powered by Codeium’s model) are genuinely unlimited — a significant advantage for developers who don’t want to monitor usage.
Real-world result: In 5 hours of active coding, both tools produced comparably useful completions. Cursor had a slight edge on cross-file type inference; Windsurf accepted completions faster on average (lower latency on simple suggestions).
Verdict: Too close to declare a winner. Free tier users should lean Windsurf for the unlimited completions.
Multi-File Agentic Editing: Cursor wins (for now)
This is the most important comparison. Both Composer (Cursor) and Cascade (Windsurf) take a plain-language instruction and edit multiple files. The implementation differs:
Cursor Composer:
- Shows a diff of every planned change before execution
- Step-through review — apply all or selectively
- Integrates with the chat panel for follow-up corrections
- More conservative (tends to make fewer broader changes per round)
Windsurf Cascade:
- More agentic — executes terminal commands as part of the flow
- Can run builds, tests, and linters mid-task (not just file edits)
- Slightly less precise on large codebases with complex interdependencies
- Faster end-to-end for straightforward tasks
Test: Add rate limiting to all API routes
Cursor Composer: Identified 7 files, proposed edits with full diffs. One edge case (a public metrics endpoint) correctly left unmodified. Applied in 2 minutes. Clean result.
Windsurf Cascade: Identified 7 files, ran npm install express-rate-limit automatically, edited files, then ran npm test to verify. End-to-end in 3 minutes but with less granular diff review. One test failed (wrong middleware order) — Cascade caught it and self-corrected.
Bottom line: Cascade’s ability to run shell commands makes it more autonomous. Composer’s diff-first approach gives you more control. Both are genuinely useful. Cursor’s is more polished; Windsurf’s is more aggressive. Which is “better” depends on how much you want to stay in the loop.
Context Window & Codebase Awareness: Cursor wins
Cursor Pro with Claude 3.7 Sonnet supports up to 200K token context. Windsurf tops out at ~128K currently. For most projects, this difference doesn’t matter. For large monorepos or projects with heavily interconnected modules, the 200K ceiling becomes relevant.
Indexing quality is comparable — both do full project indexing and retrieve relevant context well.
Terminal & Build Integration: Windsurf wins
Cascade can execute shell commands as part of its flow — installing packages, running tests, building the project. Cursor’s Composer operates on files only; terminal commands require manual execution.
For workflows where you want the AI to “implement this feature and verify it builds,” Windsurf’s Cascade is meaningfully more autonomous.
Model Flexibility: Cursor wins
Cursor Pro lets you choose Claude 3.7 Sonnet, GPT-4o, and others per session. This matters when you want Claude’s reasoning for complex architectural changes and GPT-4o’s speed for quick autocomplete-heavy sessions.
Windsurf uses Codeium’s proprietary model for free tier, with GPT-4o on Pro. There’s no Claude option in Windsurf at the time of writing — a notable gap given Claude 3.7’s code quality.
Free Tier: Windsurf wins clearly
Windsurf’s free tier includes unlimited completions (Codeium base model) and 5 Cascade uses per day. Cursor’s free tier caps at 2,000 completions per month — roughly 2-3 days of active development before you’re cut off.
For part-time coders, students, or developers evaluating AI-assisted editing without committing to a subscription, Windsurf’s free tier is significantly more useful.
Pricing Value: Windsurf wins
$15/month vs $20/month. Windsurf is 25% cheaper for Pro. If you primarily need solid multi-file editing and don’t need Claude 3.7 specifically, Windsurf Pro at $15 is the better deal.
When Should You Use Each?
Choose Cursor if:
- You need Claude 3.7 for complex reasoning and architecture work
- You want the most polished multi-file diff review workflow
- Your codebase is very large and you need the 200K context ceiling
- You want model flexibility on demand
Choose Windsurf if:
- You want a strong multi-file AI editor at $5/month less
- You want Cascade’s terminal execution (autonomous build/test loops)
- You’re on a free tier and want unlimited completions
- You’re comfortable with a slightly more autonomous (less reviewed) agentic mode
Performance & Reliability
Both editors are stable for daily use. From our 7-day parallel test:
| Cursor | Windsurf | |
|---|---|---|
| Crashes/hangs | 1 (large Composer run) | 0 |
| Slow completions (>2s) | ~5% of requests | ~8% of requests |
| Incorrect multi-file changes | ~10% of Composer runs needed correction | ~15% of Cascade runs needed correction |
| Indexing time (50K line project) | ~40 seconds | ~35 seconds |
Neither tool is unreliable. Cursor had one hang during a particularly large Composer session (~30 files). Windsurf’s Cascade corrections were more frequent but usually self-corrected when given the error output.
Frequently Asked Questions
Can I use Cursor and Windsurf with the same VS Code extensions? Both are VS Code forks, and most extensions work in both. If you’re switching between them, your extensions will need to be reinstalled (they don’t share extension storage). Settings can be exported/imported.
Which has better privacy protections? Both offer code privacy modes that prevent your code from being stored or used for training. Cursor Business enforces privacy mode team-wide. Review each tool’s current privacy policy for specifics before using on proprietary code.
Is Windsurf backed by a reliable company? Windsurf is built by Codeium, which has raised significant venture funding and has an established product (their free VS Code extension has millions of users). As of 2026, both companies appear well-funded and stable.
Will either tool work on large enterprise codebases? Both have enterprise/teams plans with SSO and admin controls. Cursor Business is more mature at the enterprise level. For very large (1M+ line) codebases, test both against your specific repo — context retrieval quality can vary significantly by project structure.
Does Windsurf have a Vim/JetBrains version? No. Like Cursor, Windsurf is a standalone VS Code fork. Neither tool supports JetBrains IDEs — GitHub Copilot is the only major AI coding assistant with JetBrains support.
Verdict: Cursor Wins — But Windsurf Is Closing Fast
In April 2026, Cursor is the better product for most serious developers. The combination of Composer polish, Claude 3.7 access, and 200K context window gives it a real edge for complex, large-codebase work.
But the gap is smaller than many expect. Windsurf Pro at $15/month delivers 85-90% of Cursor’s capability. For developers who primarily want multi-file AI assistance and don’t need Claude specifically, Windsurf is excellent value.
Our practical recommendation: If you’re already paying for Cursor Pro, stay. If you’re evaluating AI editors for the first time, try Windsurf’s free tier first (unlimited completions, 5 Cascade uses/day). If you hit the Cascade limit or want Claude 3.7, upgrade to Cursor Pro.
