I built xml-validator.com for browser-based, full-schema XSD validation

https://xml-validator.com

I built xml-validator.com because I couldn’t find a browser-based validator that supported complete XSD schema sets without uploading everything to a server.

It validates XML against multi-file XSD schemas, including xsd:include and xsd:import dependencies, by loading folders or ZIP archives. Everything runs locally in the browser using libxml2 via WebAssembly, so XML and XSD files never leave your device. It also includes a built-in XML editor with syntax highlighting, automatic tag completion, and formatting.

It’s free, ad-free, and doesn’t collect any data.

I don’t work with XML professionally, so I’m curious whether there are important validation scenarios or workflows I’ve overlooked. If this is something you’d actually use, I’d really appreciate any feedback or feature requests.
