No description of mult.dev yet.
databooq is a live-seat form builder for workshops, classes, and signups where capacity actually holds. Seats are checked at the database, not the browser, so counters update in real time and nothing ever oversells. Full sessions automatically queue a waitlist, confirmed seats get a calendar...

As answered by people managing mult.dev 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.
