LibreBooking is described as 'Open-source resource scheduling solution. It provides a flexible, mobile-friendly, and extensible interface for organizations to manage resource reservations. The "develop" branch contains the latest code of the project' and is an app. There are three alternatives to LibreBooking for Self-Hosted, Mac, Windows and Linux. The best LibreBooking alternative is Booked Scheduler. It's not free, so if you're looking for a free alternative, you could try Classroombookings or Rapla.
Booked (formerly phpScheduleIt) is a simple but powerful reserve-anything scheduler. With flexible layouts, custom rules, a powerful administrative backend, and an unbelievably simple user experience, Booked can fit almost any need.
