What is XSDHub used for?

XSDHub helps developers check XML syntax, validate against XSD schemas, format documents, and validate e-invoices against standard formats like EN 16931 and XRechnung. The tools bring the document, schema and validation result together in one browser workbench.

Does XSDHub upload my documents?

Default XML syntax, formatting and XSD 1.0 checks run on your device locally. XSD 1.1, Schematron and second-engine checks upload documents only with your explicit permission. Cloud saving uploads project schemas, not XML documents.

What are the limits for file size and number of schemas?

All plans support up to 10 MB per XML document and 1 MB per schema. Free and Pro users can work with up to 100 schemas per project (10 MB total). Pro includes 10 cloud projects with up to 50 versions each and 10 saved schemas. Team includes 50 cloud projects and 100 shared schemas.

What is included with the API access?

Pro includes 300 validations and 250 invoice checks per UTC day with an API key. Team includes 1,000 validations and 1,000 invoice checks per UTC day shared per workspace. Anonymous access is limited to 10 requests per minute per IP. No SLA is included.

What happens when a subscription ends?

When paid access ends, the free workbench remains available. Access to paid schema libraries and team features stops. Subscription cancellation does not automatically delete an account or stored schemas. Users can contact support to request deletion or help retrieving their own data.
