RSVP-System is an open-source Drupal platform for reservation and event management, built for the real-world complexity of community organizations, educational institutions, and local government. Developed by Gluebox.com LLC, it packages years of client-site experience into a composable suite of Drupal recipes — making it straightforward to stand up a fully featured events and reservations workflow without starting from scratch.
The project is actively validated against live client sites and designed to grow: each recipe is modular, well-documented, and built around clear architectural decisions so your team can adopt what fits and extend what doesn't.
