The following is a guest post from DrupalCon Vienna Marketing Committee.

When the Drupal community gathers, something extraordinary happens.

From 14 to 17 October 2025, nearly a thousand people came together at the Austria Center Vienna, Austria to celebrate open source, exchange ideas, and contribute to the future of Drupal.

DrupalCon Vienna 2025 was not only a conference, it was a living example of collaboration, diversity, and innovation in action.

A Community in Numbers

This year's event welcomed 935 registered participants, with an impressive 96.04% check-in rate.

Interest in DrupalCon Vienna built steadily through the year, with the highest number of registrations coming in June (307) and September (236).

A Truly Global Audience

DrupalCon Vienna brought together a remarkable mix of voices and perspectives.
Participants represented over 40 countries, with 85% coming from across Europe, 8% from the United States, and 7% from other regions.

The top ten countries represented were:

• United Kingdom (112)

From Costa Rica to Kenya, from Armenia to New Zealand, attendees crossed borders, time zones, and languages to connect through one shared passion - Drupal.

New Faces and Familiar Friends

One of the most inspiring aspects of the Drupal community is its balance between newcomers and long-time contributors.
