What we're about

Public Group

The Java platform and its ecosystem is more vibrant than ever. Brussels is a great city full of talent.

Mix both, and you'll get the BruJUG, a local Java User Group where passionate Java developers can, for FREE, attend presentations given by passionate speakers.

Since 2010, a simple formula: an evening session with one (or more) speaker(s) on various tech topics, followed by a well deserved drink/meal in a pub nearby for anyone interested in following the discussion.

Our stage is open to technology experts, developer advocates, but also to any of you willing to share parts of his/her knowledge with the crew.

Stay in contact:

• Twitter: @BruJUG (

• Slack: Invite link (

Do you want to come for the first time, but worry to be lost and alone in the crowd? No problem, just drop us a nice (private) mail/message and we will take care of you, and we promise to make it as nice and pleasant experience.
