Drupal & Tech Articles by Metadrop

Engineering knowledge from real Drupal projects

Everything published here comes from production work: the contributed modules we maintain on drupal.org, the migrations, upgrades, and audits we deliver for enterprise clients, and the tooling we build to raise quality on every project. We document what we learn so your team can apply it.

Topics we write about regularly:

Drupal development — architecture, contributed modules, upgrades, migrations, and performance
AI and automation — practical AI integrations in Drupal, LLM tooling, and editorial workflows
Web accessibility — WCAG compliance and the European Accessibility Act
DevOps and infrastructure — hosting, CI/CD, local environments, and platform migrations
Software quality — testing strategy, Behat, PHPUnit, and QA tooling
