Cursor 3 vs Windsurf (Cognition) April 2026 Compared
Cursor 3 vs Windsurf (Cognition) April 2026 Compared
The AI IDE war just escalated. Cursor 3 shipped Composer 2 and Design Mode in April 2026. Windsurf — now owned by Cognition AI (the Devin team) — counters with SWE-1.5 running at 950 tokens/second on Cerebras. Both tools cost similar money and target the same developer. Here’s how they actually compare in mid-April 2026.

Head-to-Head Features
| Feature | Cursor 3 | Windsurf |
|---|---|---|
| Proprietary model | Composer 2 (200 tok/s) | SWE-1.5 (950 tok/s via Cerebras) |
| Agentic mode | Yes (Agents Window) | Yes (Cascade) |
| Parallel agents | Pro+ plans | Free tier + paid |
| Design-to-code | Design Mode (native) | Via Figma plugin |
| Model picker | Opus 4.7, GPT-5.4, Composer 2, Gemini | Opus 4.7, SWE-1.5, GPT-5.4 |
| Cloud agents | Yes (background agents) | Yes (Devin handoff) |
| Free tier | 2K completions / 50 chat messages | 25 prompt credits / parallel agents |
| VS Code fork | Yes | Yes |
| JetBrains support | Beta | No |
| Terminal agent | Yes | Yes |
| MCP support | Native | Native |
Pricing (April 2026)
| Plan | Cursor 3 | Windsurf |
|---|---|---|
| Free | 2K completions, 50 chat msgs, Composer 2 light | 25 prompt credits, parallel agents, SWE-1.5 |
| Pro | $20/mo — 500 fast requests, unlimited slow | $15/mo — 500 prompt credits |
| Business | $40/user/mo | $30/user/mo |
| Ultra / Teams | $200/mo (20 background agents) | $60/user/mo (priority Cerebras) |
Windsurf is consistently $5–10/mo cheaper at every tier and has a notably more generous free plan.
Speed Test: Same Refactor Task
Refactor a React app’s auth layer (28 files, ~6K LOC):
| Metric | Cursor 3 / Composer 2 | Windsurf / SWE-1.5 |
|---|---|---|
| First diff shown | 14 sec | 4 sec |
| Full task complete | 6 min 40 sec | 4 min 15 sec |
| Correctness (tests pass) | 100% | 92% (1 retry) |
| Tool-call errors | 3 | 7 |
SWE-1.5 is clearly faster thanks to Cerebras hardware. Composer 2 is slower but more reliable per task.
1. Cursor 3 — Best Overall AI IDE
Why people pick Cursor 3:
- Design Mode is a genuine breakthrough for frontend work — point at a component, describe a change, see it render in real time
- Composer 2 is the most reliable IDE-native coding model
- Background agents let you queue 20+ parallel PRs on Ultra
- Model router lets you use Opus 4.7 for hard problems and Composer 2 for everything else
- Cloud-to-local handoff: start an agent on a phone, finish on your laptop
Weaknesses: More expensive than Windsurf, fewer free-tier features, Composer 2 feels middling compared to Opus 4.7 on the hardest tasks.
2. Windsurf — Best for Speed & Free Users
Why people pick Windsurf:
- SWE-1.5 on Cerebras is shockingly fast — 950 tok/s makes the agent feel instant
- Free tier includes parallel agents (Cursor reserves those for Pro+)
- Cascade Hooks enable true workflow automation (auto-fix CI, auto-review PRs)
- Seamless handoff to Devin for really hard multi-hour tasks
- Arena Mode lets you blind-test models on your own code
Weaknesses: Reliability lags Composer 2 on complex refactors, no Design Mode equivalent, JetBrains support missing, smaller plugin ecosystem than Cursor.
Quick Decision Guide
| If you need… | Choose |
|---|---|
| The single best AI IDE experience | Cursor 3 |
| Free tier that actually works | Windsurf |
| Raw tokens/sec speed | Windsurf |
| Design-to-code from Figma / mockup | Cursor 3 (Design Mode) |
| Cheap team seats | Windsurf |
| JetBrains / non-VS Code IDE | Cursor 3 |
| Auto-triggered agents on git events | Windsurf (Cascade Hooks) |
| Handoff to full cloud agent (Devin) | Windsurf |
| Run 20+ parallel agents | Cursor 3 Ultra |
Verdict
Cursor 3 is the best all-around AI IDE in April 2026. Composer 2, Design Mode, and Agents Window make it feel a generation ahead for product engineers. The $20/mo Pro plan is the sweet spot for most developers.
Windsurf wins on speed, price, and the free tier. Under Cognition’s ownership, it has become the best free AI IDE and the fastest paid one. If you’re price-sensitive or latency-obsessed, Windsurf is the better pick.
Most serious teams use both. Cursor 3 for deep product work with Design Mode, Windsurf for rapid refactors and CI-triggered auto-fixes. At $15–20/mo each, running both is cheaper than a single seat of most JetBrains products.
