xmlvalid is built and run by Oleksii Babintsev, a developer from Ukraine, so questions and bug reports reach the person who builds the engine. It started as a streaming validator for XML files too large for typical online tools, and grew into e-invoicing as countries made structured invoices mandatory: business rules for EN 16931, Peppol, XRechnung and national formats in 24 countries, PDF invoices, an API, CLI and GitHub Action for CI, and monitors for XML feeds. While building it, we found and fixed a slowdown in libxml2's validation of large files and contributed the fix upstream. It launched in October 2026
