As answered by people managing CloudGPU.app and databooq.
databooq's answer:
Capacity is enforced at the database, not counted after the fact. Every seat claim is checked server-side and pushed live to everyone watching the form over WebSockets, so a form literally cannot oversell — no race conditions, no manual reconciliation after the fact. Most form builders treat capacity as a number you check afterward; databooq treats it as a guarantee.
databooq's answer:
Typeform and Jotform are built for collecting answers, not for holding a limited number of seats — capacity, if it exists at all, is usually a soft counter checked in the browser. databooq is built the other way around: the seat limit is the primitive, and everything else (calendar invites, reminders, waitlists, self-service cancellation) is the booking loop wrapped around it, included free. It's also EU-hosted in Germany and GDPR-native by design, not retrofitted, and free while in beta with no credit card required.
databooq's answer:
Anyone running an event, class, or activity with a hard capacity limit: schools splitting students across workshops or field trips, community groups and clubs managing sign-ups, small teams booking limited slots for training or office hours. The common thread is a real seat count that has to hold, not just a form that collects answers.
databooq's answer:
A school I know had to split roughly 350 students across about 10 different one-day activities every year, using whatever free tool was on hand — Google Forms or Microsoft Forms. Nothing stopped one activity from getting 200 signups while another got five, and the export was just a flat list of 350 rows that someone then had to sort and rebalance by hand, every single year. I offered to build them something that actually enforced the limit instead of counting it afterward. That fix worked, and it's the reason databooq exists.
