Stape.io's answer

Stape started in 2020 as hosting for server-side tagging. We wanted to implement server-side tracking on our sites and our client’s sites and found no easy way to do that without clear documentation on how to set it up. We decided to build a tool that will simplify server-side tracking. Over time, Stape has evolved into a comprehensive infrastructure offering custom scripts, tags, plugins, tones of education materials, and a supportive community, all aimed at simplifying server-side tracking.

xmlvalid's answer:

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

Stape.io's answer

• Cost-effective: starting at $20 for hosting. Logs are included.
• User-friendly: easy setups and clear dashboards.
• Enhanced tracking with powerful integrations and templates.
• Helpful support and a community to assist with server-side tracking.
• Compliant with security standards: ISO 27001, HIPAA, and GDPR.

xmlvalid's answer:

• Desktop editors (XMLSpy, Oxygen) are powerful but expensive and need installing; xmlvalid works in the browser for free
• Simple online validators check one schema and stop at a few MB; xmlvalid streams up to 1 GB and ships schemas with all their imports
• E-invoice validators (KoSIT, Peppol testbeds) check one format each and have no CI tooling; xmlvalid covers many formats and countries, reads PDF invoices, and has an API, CLI and GitHub Action
• Documents are validated in the browser and not uploaded

xmlvalid's answer:

• Rust and libxml2 (validation engine), compiled to WebAssembly
• SaxonJS (Schematron business rules)
• veraPDF (PDF/A checks)
• Laravel and Livewire (PHP)
• Tailwind CSS
• PostgreSQL, Redis, Meilisearch
