What MRBS is
MRBS is a free, GPL web application for booking meeting rooms and other resources. It is self-hosted: installation involves placing its files on a web server, creating database tables, and configuring the application. Bookings can repeat on flexible schedules, avoid conflicts, and be made by time or period; schedules are available in day, week, and month views, with reports also provided. Access levels cover unknown users, authenticated users, and administrators. Administrators can manage rooms and areas, edit other users’ bookings, and configure booking policies, themes, authentication, email, language, and reports. Authentication options include LDAP, NT domains, Netware, POP3, IMAP, Joomla, WordPress, Wix, CAS, and SAML, among others. MRBS supports MySQL and PostgreSQL. The installation guide requires PHP 7.2.5 or later and the iconv extension. The project identifies meeting rooms as a use case, as well as restaurant tables and flying-school aeroplanes. Its preferred support channel is the GitHub issue tracker.
