Jupiter Signup, built by PerfSpot LLC, offers an AI‑driven signup form service. Users describe their event, class, or fundraiser in plain language and the platform generates a complete registration page with payment integration (Stripe, Venmo, Zelle, etc.). It supports free RSVPs, paid classes, camps, workshops, and custom add‑ons, handling discounts, waitlists, and deadlines. The service is free to start with a 1% card processing fee, no monthly subscription, and provides developer documentation for API and MCP integration.
