Cursor vs Windsurf

Quick answer

Cursor and Windsurf are both AI-first IDEs. Cursor forks VS Code; Windsurf from Codeium is a separate Electron app. Cursor offers broader model choice including bring-your-own-key, priced at $20 per month Pro and $40 Business. Windsurf ships a more generous free tier, a strong Cascade agent, and Pro at $15 per month. Pick Cursor if you want VS Code parity and model variety. Pick Windsurf if you want a cheaper entry point and a tightly scoped agent. Both support MCP servers and VS Code extensions.

Different lineage, similar goal

Cursor and Windsurf are the two biggest names in the AI IDE category. The surface features look alike: autocomplete that understands the whole file, a chat panel, an agent for multi-file work, codebase search, support for VS Code extensions.

Underneath, the products come from different places. Cursor is a direct fork of Microsoft's VS Code source. The team takes each upstream release, applies AI patches, and ships a new build. Most VS Code extensions install and run without changes.

Windsurf is Codeium's rebuild of its earlier IDE plugin as a standalone editor. It is Electron-based and aims for VS Code compatibility but is not a line-for-line fork. Extension compatibility is close but occasionally lags Cursor when VS Code ships a breaking API change.

The lineage shapes the UX. Cursor feels like VS Code with AI sprinkled in. Windsurf feels like a fresh product that picked VS Code as a baseline.

Autocomplete head to head

Cursor Tab is the in-editor completion feature. It predicts the next 1 to 20 lines, spans multiple edits in a single accept, and reads nearby files for context. The model is Cursor-tuned and fast enough for continuous typing.

Windsurf Tab is its counterpart, trained on Codeium's completion data. On simple one-line completions the two tools are hard to tell apart. On multi-line jumps, subjective reports split: some engineers prefer Cursor's willingness to rewrite larger chunks, others prefer Windsurf's narrower suggestions that hit fewer false positives.

There is no objective benchmark that clearly picks a winner. The right move is to try both free tiers for a week each and see which feels better in your actual codebase.

Agent mode

Cursor Composer is the agent surface. You describe a task, it reads relevant files, makes edits, runs shell commands, iterates. Modes include Agent and Ask. YOLO mode auto-runs shell commands when enabled.

Windsurf Cascade is its agent. The feature set is close: multi-file edits, tool use, shell command execution, persistent context across turns. One point of difference: Cascade has what Windsurf calls Flows, a feature for multi-step automated workflows that can run without constant human approval. Cursor's equivalent lives under Background Agents and Composer's auto-run toggles.

In short-task quality the two are close. On long automated runs Cascade Flows is slightly more polished than Cursor's background agent setup.

Model support

Cursor supports a wide catalog: GPT-4o, Claude Sonnet 4.5, Claude Opus 4, Gemini 2.5 Pro, o1, DeepSeek, plus bring-your-own-key for any OpenAI-compatible endpoint. You pick a different model per surface, so Tab can run on a fast cheap model while Composer runs on a heavy one.

Windsurf runs on Codeium's own fine-tuned models by default, with access to Claude Sonnet, GPT-4o, and a few others on higher tiers. The bring-your-own-key story is narrower than Cursor's. If you have a custom Claude or GPT endpoint at work, Cursor is the easier fit.

For most engineers this boils down to: if you want Gemini or a self-hosted model, Cursor is the better choice. If you are happy with the defaults your IDE gives you, Windsurf is fine.

Pricing

Cursor offers three tiers:

• Free: 2000 Tab completions, 50 slow premium requests per month, 14-day Pro trial on signup.
• Pro: $20 per user per month. Unlimited Tab, 500 fast premium requests, unlimited slow requests.
• Business: $40 per user per month. Admin controls, SSO, privacy mode enforced, analytics.

Windsurf offers:

• Free: 5 prompt credits per day and 5 Cascade credits per day. More generous than Cursor Free for light users.
• Pro: $15 per user per month. 500 prompt credits and 1500 Cascade credits per month.
• Teams: $35 per user per month. Admin tools and centralised billing.

The free tier is the most lopsided category. Windsurf Free is genuinely usable for a student or hobbyist; Cursor Free is more of a trial. At paid tier, Windsurf is $5 cheaper per month for a feature set that covers the same ground.

On Business vs Teams, the comparison is less clean because the feature sets differ. Cursor Business has stricter privacy-mode guarantees. Windsurf Teams has simpler seat management.

Extensions and ecosystem

Both editors support VS Code extensions. Cursor, as a direct fork, has almost 100% compatibility. A few Microsoft-only extensions like Live Share do not work, but the vast majority do.

Windsurf reimplements the extension API and is close to full compatibility but occasionally trails. If you rely on a very new VS Code API, Windsurf may lag by a release or two.

For themes, keybindings, and the top 100 extensions, both work fine. For edge cases, Cursor has the fewer surprises.

Codebase context

Cursor's approach: index the workspace in the background, build an embedding store on disk, let @Codebase search that store. Explicit context helpers include @Files, @Folders, @Docs, @Web, @Git, and @Terminal.

Windsurf indexes too, but exposes the context through Cascade's automatic retrieval rather than a set of explicit @-symbols. You ask a question, Cascade pulls the relevant files on its own.

Both approaches work. The difference is stylistic: Cursor asks you to point at the context, Windsurf tries to find it for you. Engineers who like precision prefer Cursor. Engineers who want less ceremony prefer Windsurf.

MCP support

Both tools support Model Context Protocol servers. The config format is nearly identical. A server that works in Cursor will usually work in Windsurf with a one-file copy.

This matters because MCP is where integrations with GitHub, Postgres, Slack, and other services live. Neither tool has a meaningful lead here as of April 2026.

Where Cursor wins

• Model variety: GPT-4o, Claude, Gemini, BYO key all in one editor.
• VS Code parity: extension compatibility is closer to 100%.
• Explicit context control: @-symbols give you fine-grained control.
• Privacy-mode enforcement on Business plan is stricter.
• Larger community and more third-party rule packs available online.

Where Windsurf wins

• Free tier is far more generous for daily use.
• Pro is $5 per month cheaper.
• Cascade Flows polished for long automated workflows.
• Simpler context handling (less @-symbol ceremony).
• Unified agent and chat surface with less mode-switching.

A decision guide

A short list of questions that usually pick one or the other:

1. Do you want the most VS Code-like experience? If yes, Cursor.
2. Do you want the cheapest paid tier with a strong free option? If yes, Windsurf.
3. Do you care about GPT-4o or Gemini specifically? If yes, Cursor.
4. Do you want a more automated agent with less supervision? Cascade Flows lean Windsurf.
5. Does your org require strict privacy-mode enforcement? Cursor Business is the safer answer today.

Both products are strong. The right call is usually a one-week trial on each in the same codebase. By day three you will know which one feels better to you.

Team rollout considerations

For teams standardising on one, a few practical points:

• Onboarding is faster with Cursor because most engineers already know VS Code.
• Budget predictability is slightly easier with Windsurf because Pro is cheaper.
• If your team uses custom Claude endpoints or self-hosted models, Cursor is the safer default.
• Both support committed project config for shared rules and MCP servers.
• Neither locks your code: if you switch later, the repo works with either tool.

There is no wrong answer in the current landscape. Both tools are maintained, funded, and shipping updates on a regular cadence. A one-year commitment to either is low risk.
