Generate, edit, lint & test your API workflow in one place
Go from idea to tested API fast. Generate or import OpenAPI, edit with AI, lint, preview docs, and run calls in one place. Insights highlight Design/DX/Security and AI-readiness. Privacy-first and secure with your own model/key. One-click MCP export.
Hey Product Hunt, Ana from Theneo here 👋
For years we’ve been in the API docs trenches. Theneo has generated docs for 15,000+ companies worldwide, which means we’ve read a lot of specs, good, bad, and “who touched this?” Along the way we kept seeing the same pain: editing OpenAPI in one tool, validating in another, testing somewhere else, and tossing AI in the mix without a way to trust the outcome.
So we built what we wished existed.
Cursor for your API is a small, fast, standalone editor where you can:
- Generate or import OpenAPI
- Edit with AI (always with a diff before you accept)
- Lint, view docs, and test requests in the same tab
- See Insights across Design/DX/Security/AI-readiness
And, if you need it, export MCP to plug your API into agents
It’s free and there’s no sign-up. It’s also secure by design: everything runs in your browser, we don’t store specs, keys, or logs. By default you’ll see our Gemini option, but you can bring your own key and pick the model you prefer: Gemini, Claude, or ChatGPT and it stays local to your session.
This is v1. Next up: a desktop app, deeper MCP testing, broader API support, and (opt-in) saving + connecting to your repo so you can track changes over time.
If you try it today, we’d love to hear: where the flow felt great (or clunky), what you’d want in inline testing, and any real-world edge cases we should optimize for.
We’ll be here all day, thanks for giving it a spin 🙏
