A one-day build for a real charity. Judges are asking whether WaterAid Canada could adopt the result, so feasibility, oversight and cost carry as much weight as the demo.

Event guides
One page per upcoming event: what you may prepare before it starts, the rules that change your plan, how judging is weighted and what the corpus knows about events like it.
NASA International Space Apps Challenge 2026
A 48-hour hackathon on NASA data, run at hundreds of Local Events and a virtual Universal Event. Global awards pass three judging phases, so the submitted project page has to carry the project after your Local Event.
Every other indexed event, past or upcoming, is in Hackathons.Los demás eventos indexados, pasados o próximos, están en Hackathons.
