about
We're building the UK's most comprehensive hackathon directory — a single place to find every build weekend, jam and design challenge in the country, from Brighton to the Highlands.
We aggregate events from Devpost, Eventbrite, Humanitix, Luma, and direct submissions so you never miss a hackathon happening near you.
Have a hackathon to list? submit it here — live within 24 hours.
faq
How do I submit a hackathon?+
Use the Submit Hackathon button in the header. Give us the name, dates, city, registration link and a banner if you have one — we review and publish within 24 hours.
Is it free to list a hackathon?+
Yes. Standard listings are free forever. Get Featured is a paid option that pins your event to the top of the directory.
How often is the directory updated?+
Daily. We pull from Devpost, Eventbrite, Humanitix and Luma every morning, and direct submissions are reviewed the same day.
What cities are covered?+
Eight hub cities — London, Manchester, Birmingham, Edinburgh, Bristol, Cambridge, Leeds and Oxford — plus the regions that feed them, so events in Reading, Brighton, Liverpool, Nottingham, Glasgow, Sheffield, Newcastle, Cardiff and Belfast all show up under their nearest hub. Online-only events get their own listing.
Can I attend online hackathons?+
Yes. Filter by Online to see remote-friendly events, including ones run from outside the UK that accept British participants.
