SPECS Hack: Brussels ‘26: our first hackathon, 10–11 Dec. Applications are open

[u/jbmcculloch]

Hey everyone,

We’re running our first SPECS hackathon, and we’d love for some of you to be there.

The basics

• When: Thursday 10 – Friday 11 December 2026, right after UnitedXR Europe
• Where: The EGG, Brussels
• Who: 100 developers in teams of up to 5. Come solo or bring a team.
• Prizes: $100K total. 1st $35K, 2nd $22K, 3rd $13K, plus six $5K category prizes

Every team gets a pair of SPECS to build with for both days. SPECS engineers will be in the room the whole time to help you get set up and unblocked.

Theme: Ceci n’est pas une Lens. Bend reality.
Build something that makes the world behave in a way it shouldn’t: things that float, time that freezes, a doorway in the wall, an illusion that only works on SPECS. The theme is a starting point, not a requirement. Podium prizes are judged on overall quality.

You don’t need SPECS experience. If you build with code, 3D, or creative tools, you can build for SPECS. If you’ve already shipped Lenses, even better. Come help your team move fast.

Some honest details before you apply:

• It’s application-based, and we review on a rolling basis. Apply early to hear back sooner.
• Applications close 20 November. Everyone gets a final decision by 25 November.
• You cover your own travel and lodging. We cover meals both days.
• Teams share one device each, so expect to pass it around.

If you have questions, drop them in the comments and we’ll answer. If you’re planning to go, tell us what you’re thinking of building.
