What is Cactoide?
Cactoide is a self-hosted event RSVP platform built for mobile-first use. It lets anyone create events and collect RSVPs through unique URLs without requiring attendees to register. The software federates across multiple instances so public events can be discovered across a decentralized network. It includes calendar integration for one-tap calendar adds compatible with major calendar apps, plus configurable capacity limits. Deployment uses Docker Compose with PostgreSQL, and the code is licensed under AGPL-3.0.
