Show HN: XSD Viewer – Instant, privacy-friendly XSD to HTML documentation (opens in new tab)

I built a small tool to make working with XML Schemas less painful. XSD files are notoriously dense. They are verbose, deeply nested, and difficult to interpret at a glance. Tracing inheritance, sequences, and choice structures by eye is tedious. I wanted something that converts these schemas into a readable data dictionary without relying on bulky enterprise software.

Who might find it useful:

- Developers dealing with legacy integrations like SOAP, banking formats, or government APIs who need to grasp the structure fast.

- Architects who have to present schema details to less technical stakeholders.

- Analysts mapping fields who would rather not sift through raw XML.

What it does:

- Everything runs in-memory with files discarded immediately. No data ever persists.

- It presents a clean visual hierarchy that makes sequences, choices, and attributes easy to follow.

- There is no signup or login. Drop the file, get the structure.

The backend is written in Go for speed, the frontend in React, and the whole thing aims to remove friction from a task that is usually slow and messy. Feedback and feature ideas are very welcome.
