Cursor vs Windsurf vs Trae
Three AI-native IDEs — same VS Code DNA, three takes on agent-driven coding.
Cursor, Windsurf, and Trae are all AI-native IDE forks of VS Code, each with a different bet on what the editor of 2026 should look like. Cursor pioneered the category — chat panel, agent mode (Composer), tab-complete that predicts cursor jumps. Windsurf (now part of Cognition after a turbulent 2025 — OpenAI's $3B deal collapsed in July, Google licensed core tech and key staff for $2.4B, and Cognition acquired the remaining company) brought Cascade, an agent that's more proactive about reading and editing across files. Trae is ByteDance's free entrant, marrying agent and editor in a single workflow, optimized for working professionals who don't want to think about per-message pricing. The three have converged on the same surface — chat, agent mode, multi-file edits, model selection — but differ on speed of feature shipping, pricing model, and which underlying behaviors feel polished. Cursor charges for power. Windsurf differentiates on agent flow. Trae differentiates on free. This page walks through which one fits which kind of developer.
Quick verdict — which one for which task
Feature comparison
| Feature | Cursor | Windsurf | Trae |
|---|---|---|---|
| Pricing (individual) | Hobby (free); Pro $20/mo; Pro+ $60/mo; Ultra $200/mo | Free tier; Pro $15/mo; Teams $30/user/mo | Free — no paid tier |
| Owner | Anysphere (independent startup) | Cognition (post-2025 acquisitions) | ByteDance |
| Models supported | Claude (Sonnet/Opus), GPT-5, Gemini, fast Cursor-tab model | Claude, GPT, Gemini, in-house SWE-1 family | Claude, GPT, Gemini, ByteDance Doubao — generous quotas on free tier |
| Agent mode | Agent / Composer — multi-file plan + execute, terminal access | Cascade — agent that proactively reads files and proposes plans | Builder mode — multi-file agent, free model usage |
| Tab-complete quality | Cursor Tab — fastest, multi-line, predicts cursor jumps | Strong — Supercomplete is competitive but not as fast | Solid — improved significantly through 2025 |
| Background / cloud agents | Background Agents in remote sandboxes | Async agents via Cascade | Builder runs in IDE; no managed cloud agent yet |
| Privacy / enterprise | Privacy Mode + Cursor for Business; SOC 2 | Hybrid privacy mode; Teams tier with admin controls | Free, but ByteDance-owned — review your team's data residency policy |

Pros and cons by tool
Bottom line
Cursor, Windsurf, and Trae are converging fast. Cursor is the polished leader and pace-setter. Windsurf is the agent-forward alternative for developers who want the IDE to drive instead of waiting on chat. Trae is the no-budget option that's surprisingly competitive — when it's institutionally allowed. Many users subscribe to multiple — here's which task each wins: production work with privacy controls goes to Cursor, agent-led 'do this whole feature' flows go to Windsurf, hobby projects and learning go to Trae. If you're starting fresh and budget isn't the constraint, install Cursor; if budget is, install Trae and upgrade to Cursor when work demands it.
Frequently asked questions
Is Trae actually competitive with Cursor and Windsurf for paid work?
On capability for common Western dev tasks, increasingly yes. The free pricing makes Trae the most generous quota in the category, and Builder mode handles multi-file agent work credibly. The catch is institutional: many enterprises and government contractors ban ByteDance products outright, so Trae is often impossible at $0 even when it's technically the best deal.
Did Windsurf get worse after the Cognition acquisition?
The product itself is steady — Cascade still works, the IDE still ships updates. The uncertainty is strategic: how long does Cognition focus on Windsurf the IDE vs. their other agent products like Devin? If you depend on it for daily work, watch the release cadence.
Should I switch from Cursor to Windsurf to save $5/mo?
Probably not for the price alone. Switch if Cascade's proactive agent flow fits how you work better than Cursor's chat-driven flow. Both are good enough on capability that the workflow ergonomics matter more than $5.
Which one is best for someone learning to code?
Trae — free, multi-platform, no quota anxiety. The agent quality is good enough for tutorial work and small projects. Upgrade to Cursor when you hit professional projects with privacy/enterprise needs.
Can I run two of these side-by-side?
Yes, but you'll spend 30 seconds picking which one to open per project. More common: install Cursor as primary and keep Trae installed for hobby projects where you don't want quota worry.
