On paper, Windsurf and Cursor are the same product. Both are standalone IDEs forked from VS Code. Both charge $20/month for their entry paid tier. Both ship a tab-completion model and a multi-file agent. Both wire in the same frontier models — GPT-5, Claude Opus, Gemini. Reviews that score them feature-by-feature end up in 47-43 ties because the feature lists genuinely match.
That kind of comparison misses the point. The two editors feel different to use, and the difference matters more than the feature checklist. This piece tests both side-by-side across two weeks of normal client work — Python, TypeScript, Go — and lands on a clear verdict at the end about which one fits which kind of developer.
Pricing and feature claims here were verified against Windsurf's pricing page and Cursor's pricing page on May 5, 2026. Both vendors change pricing more than most editors — re-verify before subscribing.
Pricing: nearly identical
The pricing tables converged in 2025 and have stayed mirrored since:
| Tier | Cursor | Windsurf |
|---|---|---|
| Free | Hobby (limited Agent + Tab) | Free |
| Entry paid | Pro $20/mo | Pro $20/mo |
| Heavy individual | Pro+ $60/mo (3× usage) / Ultra $200/mo (20× usage) | Max $200/mo (heavy users, unlimited extra at API pricing) |
| Team | Teams $40/user/mo | Teams $40/user/mo |
| Enterprise | Custom | Custom |
Cursor offers a middle tier (Pro+ at $60) that Windsurf doesn't match exactly. Windsurf has a "Light" plan with unlimited usage on cheaper models that Cursor doesn't have. These are minor — for the typical individual developer choice, both are $20/month for Pro and $200/month for the power-user tier.
The entry decision is therefore not a price decision. It's a workflow-fit decision.
Both ship a standalone editor
A common misconception: "Windsurf is a VS Code extension, Cursor is its own editor." Both are standalone applications. Both fork VS Code. Both can install most VS Code extensions from the Open VSX Registry (with occasional compatibility lag).
Windsurf is described on its own site as "the first agentic IDE" — a standalone download, not an extension. Windsurf does also ship lighter VS Code/JetBrains plugins for shops that can't switch editors, but those plugins only include the autocomplete (Tab), not the full Cascade agent experience. The full Windsurf is the desktop app, just like Cursor.
If you absolutely cannot switch off VS Code or JetBrains, Copilot is still the only first-class option — see our companion piece below for that comparison. Windsurf's plugins are a partial answer; Cursor doesn't even pretend.
The agents feel different
This is the real story. Cursor's agent is Composer 2. Windsurf's is Cascade. Both edit multiple files. Both run multi-step tasks. Both can apply diffs and run terminals. Surface features match.
The lived difference, after two weeks of side-by-side use:
Cursor (Composer 2) has a "you stay in control" default. The agent proposes, you accept-or-reject each diff. Long agent loops surface state to you frequently. The pacing favors developers who want to pair with the AI rather than supervise it.
Windsurf (Cascade) has a "the agent runs ahead, you supervise" default. Cascade is more aggressive about chaining steps without asking. It surfaces fewer mid-loop checkpoints and writes more code per prompt. The pacing favors developers who want to hand off whole tasks and review the output later.
This isn't a knob you can flip. Both editors expose settings to slow down or speed up the agent, but the defaults and the UI affordances reinforce the different philosophies. After a week each, the difference becomes obvious. Some developers strongly prefer one; some genuinely don't care.
A third framing that might help: Cursor feels like a power tool with a trigger guard. Windsurf feels like a power tool that's already running. Both have their audience.
In-house models: Composer 2 vs SWE-1.5
Each editor ships an in-house model tuned for the agent loop:
- Composer 2 (Cursor) — fast, optimized for multi-file diffs and the agent's tool-use protocol. Faster than the frontier models for Cursor's specific workflow but doesn't outperform them on raw benchmark accuracy.
- SWE-1.5 (Windsurf) — same role. Fast, optimized for Cascade's tool-use protocol, available across all paid Windsurf tiers per the Windsurf pricing page.
For raw coding accuracy, the Aider polyglot benchmark — testing 225 exercises across C++, Go, Java, JavaScript, Python, and Rust — has GPT-5 (high reasoning) at 88.0% correct, GPT-5 (medium) at 86.7%, o3-pro at 84.9%, Claude Opus 4 (32k thinking) at 72.0%, and Claude Sonnet 4 at 61.3%. The frontier-model gap matters more than the in-house-model differentiation.
What that means: for a hard one-shot problem, you should reach for GPT-5 in either editor. For a fast iterative loop, you should reach for Composer 2 in Cursor or SWE-1.5 in Windsurf. The choice between editors is not a model choice — both editors give you the same frontier models alongside their in-house options.
Tab autocomplete: minor differences
Both editors ship a specialized completion model. Both feel snappy. Both predict multi-line completions, not just single-token next-word.
Cursor's tab is described on its homepage as "our specialized Tab model predicts your next action with striking speed and precision." Windsurf's equivalent has the additional Tab to Jump feature — instead of just completing where your cursor is, Tab can jump your cursor to a related location in the file the model predicts you want to edit next. It's a small thing that quietly changes the rhythm of editing once you get used to it.
If you exclusively want the best tab autocomplete, both are excellent and the difference is barely measurable in practice. Tab to Jump is a slight Windsurf edge for people who do a lot of cross-file refactoring; Composer 2's tighter integration with Cursor's agent is a slight Cursor edge for people who do a lot of multi-file features.
Codebase context: convergence
Both editors index the codebase semantically and let you @ mention files, functions, and folders to pull them into context. Both handle medium-sized codebases (under 200k files) cleanly. Both struggle a bit at very large monorepos but have been improving steadily.
A real difference worth knowing: Windsurf's Cascade has stronger always-on awareness of recent changes. It tracks what files you just edited and will pull them into context automatically without you needing to @ them. Cursor's Composer 2 surfaces this less aggressively and tends to need an explicit reference. For long sessions, Cascade's behavior reduces the friction of saying "remember the file I just edited;" for short, focused work, Cursor's explicit-reference style produces fewer surprises.
Where each one wins
The honest list, after two weeks of side-by-side daily use:
Cursor wins for:
- Solo devs who want to drive the AI rather than supervise it
- Workflows with frequent context switches between unrelated tasks
- Teams where seniors want to gate AI changes more carefully
- Heavy MCP users — Cursor's MCP integration is more mature
- Developers who like the keyboard-shortcut-driven Cursor UX
Windsurf wins for:
- Solo devs who want to hand off whole features to the agent
- Long agent loops on a single feature where Cascade's "keep going" default saves clicks
- Teams that value Spaces (per-project isolated agent context)
- Developers who do heavy cross-file editing — Tab to Jump is genuinely useful
- Anyone who liked Devin's autonomous-agent approach but wanted it inside an IDE
Both lose to Copilot for: any team mandated to JetBrains, Visual Studio, or Vim/Neovim. Cursor and Windsurf are both VS Code forks
