SnagTime is a free, self-hostable scheduling application that provides account and workspace management, event types, availability rules, public booking links, time-zone handling, custom booking questions, rescheduling, cancellation, and recovery links. It checks Google Calendar free/busy status and can create calendar events, sends organizer and invitee messages through SMTP, and supports Stripe Checkout in test mode with webhook confirmation and refund handling. The local demo uses SQLite, a local calendar adapter, a local email inbox, and stub payments; production deployments use a PostgreSQL architecture with a web service, background worker, persistent database, and webhook endpoints. The application is a Next.js project with Prisma schemas and migrations, distributed under the MIT License. It is intended for self-hosting rather than as a managed service; external Google Calendar, SMTP, Stripe, hosting, domain, and database services must be supplied and configured by the operator.
