Registration software

Event registration software you build by describing it

Updated 2026-08-07

Event registration software should let you stand up a real registration form fast, take payment, and cap attendance, without learning a form builder or writing code. Jupiter Signup does exactly that: describe your event in a sentence and it builds the online registration form for you, with paid ticket or session options, a capacity limit, the custom questions you need, and checkout through your own Stripe account. You edit anything afterward by chatting.

Paid on Stripe, 2% fee, no monthly cost.

Is it the right fit

Most registration software makes you build the form field by field and pay a monthly subscription whether or not you have an event running. Jupiter Signup flips both: the AI writes the whole page from a sentence, and there is no monthly plan, just a flat 2% on what you actually collect. A free RSVP costs nothing.

What you get

Built from a sentence Describe the event and the form is written for you in seconds, options, prices, capacity, and questions included.
Paid or free registration Charge a registration fee or ticket price on your own Stripe, or run a free RSVP. Money UI only appears when you charge.
Capacity and waitlist Cap the event or each session, show spots left, and open a waitlist when full. Enforced on the server so it can't be oversold.
Custom questions Collect anything you need per attendee, dietary needs, accessibility, t-shirt size, add-ons, without a schema to design.
No code, no monthly fee Nothing to install and no subscription. A flat 2% on what you collect, on top of Stripe's normal processing fee.
