Cursor vs. Windsurf for AI-Native Coding

How we testedWe gave each tool the same three refactors in the same three repos: rename a domain concept across roughly 40 files in a TypeScript codebase, swap an ORM layer in a Python service, and extract a shared package from a Go monorepo. We graded each attempt on whether the build passed, whether the test suite passed, and how many files we had to hand-correct after the tool declared itself done.

Cursor's Composer finished all three refactors with fewer hand-corrections. The TypeScript rename and the ORM swap each needed a small cleanup pass; the Go package extraction went in cleanly on the first try. Windsurf's Cascade did well on the smaller changes but lost steam on the wider ones, a pattern other reviewers have hit as well. One round-up noted that on a March 2026 standardized benchmark, "Cursor built a responsive data table component in 2 prompting rounds, Windsurf needed 3." Independent testing has also put Cursor ahead on completion-acceptance rate (roughly 72% vs. 65% for Windsurf), which tracks with what we saw. Windsurf's Vibe & Replace is genuinely useful for very wide find-and-replace-style changes across hundreds of files, and Cascade's automatic context retrieval meant it needed less handholding to find the right files in the first place. But for the kind of multi-file refactor most engineers actually do in a week, Composer produced a diff we were more willing to merge.

How we testedWe picked four open issues from our test repos (two bug fixes, a small feature, and a dependency upgrade) and assigned each one to both tools' agent mode end to end. We scored whether the agent opened a working PR, how many follow-up prompts we had to give it, whether the diff was mergeable, and how each tool handled longer-running work.

This is the round where Cursor pulls furthest ahead, and it's less about raw accuracy than infrastructure. Composer runs a plan-then-diff-and-approve loop; Cascade is more autonomous, reading files, running tests, and only asking for confirmation on ambiguous decisions. On greenfield or prototype work Cascade's autonomy is genuinely faster, but on production tickets Cursor's constant approve-the-diff rhythm is a feature. We caught two edge cases the agent would have shipped otherwise. The bigger gap is the surrounding ecosystem: Cursor now ships background automations for scheduled tasks, parallel subagents that run multiple tickets at once, and cloud agents that can work on GitHub issues without keeping the laptop open. Windsurf added parallel Cascade sessions in its Wave 13 release in early 2026 and offers cloud sessions on Pro, but the ecosystem is less mature and less composable. On our longer bug fix, one that spanned three sessions over two days, Cursor kept context better across sessions than Windsurf did.

How we testedWe installed each tool in the editors we use day to day (Cursor's own IDE, Windsurf's own IDE, JetBrains Rider and IntelliJ, and Neovim) and scored coverage, feature parity across editors, and how cleanly each tool fit a team that already has people on JetBrains. We also checked what does and doesn't migrate between the two.

Windsurf wins on breadth. It runs as a standalone editor and as plugins across 40-plus IDEs, so a team with JetBrains, Vim, or Xcode users can adopt it without forcing an editor switch. Cursor added a JetBrains path in March 2026, which removes the old "VS Code fork or nothing" objection, but coverage still isn't as broad. One other thing worth naming: Cascade writes AI generations to disk before you approve them, so the dev server shows the result in real time and you can revert if you hate it. That's a real ergonomic difference some engineers will strongly prefer to Cursor's approve-then-write model. If you're on a mixed-IDE team, or you care about seeing generated changes running in a preview before you accept them, Windsurf is the closer fit. Cursor is still the closer fit if you want the deepest integration and are willing to standardize on its editor.

How we testedWe compared current published pricing at every tier against the quota and credit models each tool now enforces, and modeled a year of cost for a 10-person engineering team with mixed usage. We also factored in the billing changes both tools shipped in the past year.

This is a narrower win than it would have been a year ago. Cursor Pro is $20/month with a monthly credit pool equal to the plan price ($20), Pro+ is $60, Ultra is $200, and Teams is $40 per seat. Windsurf Pro is also $20/month after the March 19, 2026 pricing overhaul that swapped monthly credits for daily and weekly quotas, with Max at $200 and Teams at $40 per seat. On paper the tiers match almost exactly. Cursor edges the round on two things. First, its Auto mode routes to a cost-efficient model and is effectively unlimited on paid plans, so most everyday work doesn't touch the credit pool at all; Windsurf's quota system caps how much Cascade you can run in a given day regardless of what's "left" for the month, which hurts sprint days. Second, both tools charge API rates for overage, and Cursor's usage dashboard and per-model routing gave us tighter control. Windsurf's counter is SWE-1.5, its in-house model that covers routine agentic work without burning frontier tokens. If most of your Cascade sessions can ride on SWE-1.5, the quota stretches meaningfully further. For a team that lives in the agent, the two tools now cost about what the work costs. Cursor just gives you slightly more room to steer.
