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 🙏
recommend: think about desktop app release, more flexible for local works
Tried using it on a pretty messy spec, and honestly, it fixed things faster than I could’ve done manually. That’s a real timesaver. Just curious if it can handle merging multiple specs into one?
This is such a smart move 👏 The pain of juggling multiple tools just to get an API spec right is so real. Having generation, editing (with AI + diff), linting, docs, and testing all in one lightweight place feels like a huge win for both speed and trust
Really like this approach! The fact that everything runs in the browser and nothing is stored makes it feel both fast and secure. One thing I’m curious about: how well does the AI handle edge cases in larger, messy OpenAPI specs? I imagine a lot of teams will throw pretty complex files at it.
Get insights on Design, DX, Security, and AI-readiness. Privacy-first, secure with your own model/key, and one-click MCP export.
For many, this might just feel like another useful product. But for me, it’s incredibly special. I had the privilege of watching it come to life, step by step, line by line and being part of the journey as it grew from an idea into a product we can proudly share with the world.
While most outside Theneo were using other API editors, I had this unique privilege of testing and using our own product 😄 even before the launch. And honestly, it made the experience even more exciting!
I’d love for you all to try it out, share your feedback, and tell us what more we can improve, the more insights, the better 🙌
And @ana_robakidze , up until now I’ve been deep into rigorous testing… but I can’t wait to start building and developing more features for this amazing product 🚀🚀
This looks like exactly what the API development community has been waiting for! The "Cursor for your API" concept is brilliant - finally a unified tool that handles the entire API workflow from design to testing.
I'm particularly impressed by three aspects:
1. The browser-based security approach - keeping specs and keys local is crucial for enterprise adoption
2. The MCP export functionality for agent integration - this positions APIs perfectly for the AI-first future
3. The intelligent diff preview for AI-generated changes - building trust in AI assistance
The one-click workflow from OpenAPI generation to tested endpoints could be a game-changer for API-first teams. Looking forward to trying the desktop app when it launches!
@ana_robakidze Congrats on solving such a real pain point in the developer experience. The timing couldn't be better with the growing focus on AI agents and API standardization.
I've participated in testing the features before launch and I'm very excited for the release! Can't wait for the feedback!
I wrote our docs in Mintlify + Cursor + Claude Code. Our OpenAPI was a mess since it's auto-generated from our FastAPI backend. However, I think ~5 prompts to Cursor/CC was enough for publishing. Does this add to that flow? Maybe this isn't meant for docs built with Mintlify?
Thrilled to finally share what our team has built! 💖
I got to shape the design and experience ✨ Can’t wait to hear what you think
Thrilled to be a part of this whole project. The MCP server generation was the most interesting to test out.
Congrats on rhe launch! 💫 just in time to try for my next code rewrite. So how does it compare with Theneo itself? or is this Theone? 🤔
We've been using Theneo for 3+ years already. Absolutely love the product and the team!
congrats on the launch @ana_robakidze. This is a well thought, well built product ready to scale.,🚀
APIs are getting more relevant. For many projects, the revenue model is shifting from "owning the UI" to an API-dominated one. Generating APIs for your project will be very important going forward. Great to see Theneo building the right tool.
This looks impressive. I gave it a try and was honestly surprised. First time I asked questions or composer stuff it felt slow, but then it got way better. I see you’re using 2.5 pro as default makes sense. I tried lite, super fast, but yeah the quality on 2.5 pro is way better. MCP is nice for local, but I’d love more options. I get the value of having everything in one place: polish the spec, fix some issues, and then roll it out. Would love to see more config options though + ability to host on your side would be awesome. Overall impressive!
This is incredibly good! It serves as the perfect illustration of how companies must adapt to all the modern changes. Best of luck @ana_robakidze
