Comparison
Cursor vs Windsurf: which AI code editor should you use in 2026?
Cursor has the better autocomplete, the bigger ecosystem, and credit-based pricing that can surprise you. Windsurf has the stronger long-task agent, unlimited autocomplete on every plan, and quota-based pricing that is easier to predict. Both are $20 a month at the Pro tier. Developers who type a lot pick Cursor; people who hand off longer tasks lean Windsurf.
At a glance
| Cursor | Windsurf | |
|---|---|---|
| What it is | VS Code fork with AI built in | VS Code fork with AI built in |
| Autocomplete | Best in class multi-line Tab | Good, unlimited on all plans |
| Agent | Agent mode, diff review per step | Cascade, keeps context across long tasks |
| Free tier | Hobby, limited | Free, daily and weekly quota |
| Pro price | $20/month | $20/month |
| Top individual tier | Ultra $200/month | Max $200/month |
| Billing model | Credits, burn depends on model choice | Daily and weekly quotas since March 2026 |
| Ecosystem | Largest: rules, MCP, tutorials | Smaller but growing |
| Our scan data | 120 repos, 12.5% with a high finding | Not enough attributed repos to report |
Cursor is a fork of VS Code with the AI built into the editor itself: Tab autocomplete that predicts multi-line edits, an Agent mode that plans and edits across files, and chat with your whole codebase as context. You keep your extensions, keybindings and files; the AI is a layer over an editor you already know.
- Tab autocomplete is the best in class for predicting the next edit, not just the next token
- Agent mode handles multi-file changes with a diff you review before accepting
- Largest community, most tutorials, most rules files and MCP integrations published for it
- Works with your existing VS Code setup on day one
- Credit-based billing surprises people who lean on the strongest models
- Agent can wander into refactors you did not ask for on long tasks
- Heavier than plain VS Code on large monorepos
- Hobby: free, limited
- Pro: $20/month
- Pro+: $60/month
- Ultra: $200/month
- Teams: $40/user/month
- Paid plans include a credit pool roughly equal to the price; picking frontier models manually over Auto mode burns it faster
Windsurf, from the team behind Codeium, is also a VS Code fork. Its centerpiece is Cascade, an agent that keeps a running model of what you are doing across the editor, terminal and previous steps, so it can carry a longer task without being re-briefed. It shipped a browser preview and deploy flow inside the editor earlier than most competitors.
- Cascade is strong at long, multi-step tasks where it needs to remember what it already tried
- Unlimited Tab autocomplete on every plan, including free
- Quotas are simpler to predict than per-model credit burn
- Cleaner first-run experience for people new to AI editors
- Smaller ecosystem: fewer community rules, guides and integrations than Cursor
- Quota resets can interrupt a heavy day of work
- Tab completions are good but a step behind Cursor's on multi-line edits
- Free: light daily and weekly quota, unlimited Tab autocomplete
- Pro: $20/month
- Max: $200/month
- Teams: $40/user/month
- Since March 2026, all plans use daily and weekly quotas instead of monthly credits; annual billing saves roughly 17 to 20 percent
What our scans found
This is the part other comparisons cannot write. We statically scanned 2,148 public repos built with AI tools and probed 4,740 live apps, then published the anonymised data. Here is what it says about apps built with these two.
Cursor-attributed web apps had the second-lowest rate of high-severity findings among the tools we scanned. The most common serious issue was still a hardcoded credential. Details
We do not yet have enough repos reliably attributed to Windsurf to publish a rate. The failure patterns come from the underlying models and prompts rather than the editor, so expect the same top issues: hardcoded credentials and missing authorization checks.
Repo rates are upper bounds from a static scanner and the corpora were sourced differently, so treat the numbers as directional. Method, limits and the CSVs are on the research page.
Which one should you pick?
You write most of your own code and want the AI to finish your thoughts. You care about the widest set of community rules and integrations. You are fine watching credit usage.
You hand the agent longer tasks and want it to remember what it tried. You want predictable limits over metered credits. You are newer to AI editors and want the gentler on-ramp.
Or both. Both are VS Code underneath, so switching costs an afternoon. Plenty of people run the two free tiers side by side for a week and keep the one they reach for.
Frequently asked questions
Is Windsurf better than Cursor?
For long agent-driven tasks, often yes: Cascade holds context across steps better than Cursor's agent. For autocomplete while you type, Cursor is ahead. Neither is better overall; they are tuned for different working styles.
Is Cursor or Windsurf cheaper?
Both charge $20 a month for Pro. The difference is the model: Cursor uses credits that burn faster when you manually pick frontier models, Windsurf uses daily and weekly quotas. Light users pay the same; heavy users of top models usually spend more on Cursor.
Can I use Cursor and Windsurf on the same project?
Yes. Both are editors over the same files and git repo. Nothing in the project is tied to either tool except the rules files each one reads, and those can coexist.
Does either one write more secure code?
Not meaningfully; they share the same underlying models. In our scans, 12.5% of Cursor-attributed web apps had at least one high-severity finding, usually a hardcoded credential. We do not yet have enough Windsurf-attributed repos to report a number. The mistakes come from the model and the prompt, not the editor, so scan the output regardless of which you use.
Whichever you use, the output has the same handful of mistakes. Paste a URL or a public repo and see them in thirty seconds. No account.
