FAQs
What hackathons are on in London this month?
Everything in the list above: every upcoming hackathon in London for the next 90 days, soonest first, checked against each organiser’s page every morning. To hear about new ones, get the weekly email.
How is this list made?
Each morning we look for new London events and check each one at its source: Luma, Eventbrite, Meetup, Devpost or the organiser’s own site. Dates, times and venues come from that source.
What counts as a hackathon?
Events where people build something: hackathons, buildathons and hack nights. Talks, networking-only events, training, online-only and cancelled events are left out. More in what is a hackathon?
I’m new to hackathons. Where do I start?
Our guide for beginners covers what happens, how to prepare and how to pick your first event. A hack night or one-day event is a good start.
Is it free?
Yes. The list and the weekly email are free. Some events charge for tickets, and the event page will say.
