I published a prototype in seconds. I pasted some HTML, uploaded a CSV, and immediately had a shareable site plus a working API with copyable docs. Password protection and API key controls worked exactly as expected. If you want to ship demos or internal tools fast without setup or school demo/project for students, this saves hours.
I built Miniup to scratch a specific itch: sometimes I just want to upload a file and share a link, without repos, build steps, or setting up infrastructure.
A lot of “instant hosting” tools work for simple pages, but they usually hit one of two walls for me: free plans cap how many projects you can create, and most of them don’t give you a quick way to turn a spreadsheet into a real API. My AI-generated HTML pages are usually under 1MB, but many demos still need live data and API calls.
I kept running into the same two problems:
I needed a fast way to share small HTML prototypes (often AI-generated) as a real link.
I needed a real backend for demos, but I only had a spreadsheet.
Miniup solves both in one flow: publish a static site from HTML/ZIP/folder, then upload a CSV/Excel to instantly get a REST API your frontend can call. It auto-generates OpenAPI docs, and if you need write access you can issue a write key, rotate it anytime, and toggle methods per table.
If you try it, I would love your feedback for improvement.
