Features and specs

What each product offers, as listed by its team.

Lemmy 6 features
xmlvalid 19 features
  • Decentralization
    Lemmy is built on the ActivityPub protocol, making it part of the larger Fediverse, which promotes distributed and federated networks, reducing reliance on a single central authority.
  • Privacy
    Being open-source, users can audit the code for security vulnerabilities. Furthermore, federated networks tend to have better privacy controls compared to centralized social media platforms.
  • Open-source
    Lemmy's code is publicly available, allowing anyone to contribute to its development or create their own instances, fostering a community-driven approach.
  • Customization
    Instance administrators can tailor the appearance, rules, and functionalities of their Lemmy instances, offering a more tailored user experience.
  • Community Control
    Communities on Lemmy have more control over their content and moderation policies, which can result in higher quality discussions and interactions.
  • Reduced Censorship
    Because Lemmy is federated, there's less chance of blanket censorship as different instances can have varying rules and policies.

Possible disadvantages

  • Smaller User Base
    Compared to mainstream social media platforms like Reddit or Facebook, Lemmy has a smaller user base, which can limit the variety and volume of content.
  • Learning Curve
    New users might find it challenging to understand how decentralized networks and federated instances operate, which can be a barrier to entry.
  • Instance Fragmentation
    Content and user communities are spread across multiple instances, which can lead to fragmented discussions and a lack of unified content discovery.
  • Variable Quality
    Since any instance can have its own moderation rules, the quality and tone of discussions can vary greatly between instances, potentially leading to inconsistent user experiences.
  • Technical Expertise Required
    Running and maintaining a Lemmy instance requires technical knowledge, which might not be accessible to general users without background in system administration.
  • Limited Features
    As a relatively new and developing platform, Lemmy might lack some features and functionalities that users are accustomed to on larger, more established platforms.

Questions & Answers

As answered by people managing Lemmy and xmlvalid.

Which are the primary technologies used for building your product?

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
  • Cloudflare

What makes your product unique?

xmlvalid's answer:

  • Schema validation and e-invoicing business rules in one place: XSD, DTD and RelaxNG, plus 7,700+ Schematron rules of EN 16931, Peppol BIS and PINT, XRechnung, Factur-X and national formats from France and Italy to Saudi Arabia, Mexico and Brazil
  • Built for large files: a streaming Rust engine (libxml2 compiled to WebAssembly) validates documents up to 1 GB in the browser with flat memory (5 GB tested)
  • 177 official schemas ready to use, and e-invoice profiles detected automatically from the document
  • E-invoice PDFs (Factur-X, ZUGFeRD, ISDOC) checked whole: the XML inside, PDF/A, and the PDF's text against the XML
  • Every error links to a page explaining why it fails and how to fix it, for libxml2, Java and .NET messages
  • The same checks in CI and integrations: REST API, SOAP, MCP server for AI agents, CLI, GitHub Action, n8n

Why should a person choose your product over its competitors?

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

How would you describe the primary audience of your product?

xmlvalid's answer:

  • Developers and integrators building or receiving e-invoices (Peppol, XRechnung, Factur-X, FatturaPA, KSeF, ZATCA, CFDI, NF-e, UBL, CII)
  • ERP and accounting software vendors preparing for national e-invoicing mandates
  • Teams that exchange XML with partners: payments (ISO 20022), healthcare (HL7 CDA, FHIR), feeds and sitemaps
  • DevOps engineers who want XML checks in CI pipelines
  • Anyone who needs to validate a large XML file quickly without installing software

What's the story behind your product?

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
