Detailed Review

Open Social is built by Open Social B.V., which describes itself as an Amsterdam company with exclusively Dutch investors. It is built on Drupal and Mautic, and its public core distribution is free on Drupal.org while the commercial platform adds features through a subscription. Its customers named on its site include the European Commission, IATA and Greenpeace.

It publishes the most detailed sub-processor list in this category. Hosting runs on Upsun (formerly Platform.sh) in France, backups on Hetzner in Germany, the CDN on Bunny.net, with legacy Cloudflare and a US email provider flagged for removal on dated deadlines in 2026. The customer chooses the deployment region, EEA or United States, and the vendor states ISO 27001 certification.

There is no public price list, only a demo request, so cost is a sales conversation. It is aimed at large organisations, with isolated single-tenant hosting. Compared with HumHub it is sold mainly as a managed service rather than as software you run yourself, and the Drupal base suits teams that already work in Drupal.

What Open Social does well

  • Dutch company, with a subprocessor list naming each provider and region
  • Open-core Drupal distribution available free on Drupal.org
  • Single-tenant hosting with a selectable EEA region
  • ISO 27001 stated by the vendor
  • Customers include the European Commission and IATA, per the vendor

Where Open Social falls short

  • No public pricing
  • Some legacy deployments still use US sub-processors until their removal dates
  • US region available as a choice
  • Enterprise focus, not suited to small communities

Standout feature. A sub-processor list that names every provider, region and jurisdiction, which few competitors publish.
