XSDHub

From the vendor

In XSDHub’s own words

XSDHub is built by Daniel Haket, who also operates AIBuilder Marketplace. This is our own product, not an independent endorsement.

Validate XML locally against multi-file XSD 1.0 projects. Optional server engines support XSD 1.1, second-engine comparison and Schematron XPath 1.0 with explicit upload consent.

Save and export local projects with five revisions. Pro and Team support complete cloud schema projects with up to 50 versions. File tabs, find/replace, error-line markers, structural schema comparisons, a dependency graph and a validated example-XML generator support editing.

Explicit public HTTPS import downloads schema dependencies as a snapshot. Private network fetching and DTDs are blocked. XML allows 10 MB; schemas 1 MB each and 10 MB total per project. Import is limited to 20 files.

Pro includes local batches of 25 files; Team includes five seats and batches of 100. Server batches allow ten files, subject to rate limits. API, Python CLI and a GitHub Actions starter support automation.

No enterprise SLA, XPath 2.0 Schematron or certification is promised. Complex generated examples may need manual work. See the linked review for actual test coverage and remaining verification limits.

Pricing: Free; Pro US$19/month or US$190/year; Team US$49/month or US$490/year. Annual plans billed yearly; applicable tax extra. Checked 26 October 2026. (vendor-stated — always verify on their site)
