What OpenRSVP is
OpenRSVP is a self-hosted platform for creating event invitations, managing RSVPs, and communicating with guests. It is presented for birthdays, gatherings, and celebrations. Organizers can choose among five customizable themes and adjust colors, fonts, and text. Guests can RSVP without an account, while organizers can track dietary needs and plus-ones, import guest lists from CSV, and offer event guestbooks. The platform supports scheduled reminders and two-way messaging between organizers and attendees. Email options include SMTP, SendGrid, and SES; SMS options include Twilio, Vonage, and SNS. Its documented API is under /api/v1, and webhooks can send real-time, HMAC-signed callbacks for RSVP and event lifecycle events. OpenRSVP can run as a Docker container and supports SQLite or PostgreSQL. The project is MIT licensed and says it has no ads or tracking. Repository details describe configurable data retention that defaults to 30 days after an event. Bot protections include honeypot fields and IP-based rate limiting. SendGrid and SES delivery webhooks record bounces and complaints but do not yet verify provider signatures.
