AdamRMS
Since 2019
PHP
Free, open source rental management system for theatre, AV and broadcast
AdamRMS tracks equipment across sites and events, and manages the projects it goes out on: crewing, finance and invoicing, maintenance jobs, training records and crew recruitment, with granular permissions for each team member.
It's free to self-host from a prebuilt Docker image, or available as a hosted service. It's built with PHP, Twig and MySQL, and licensed under the AGPL-3.0.
