Galene is a self-hosted video conferencing system that runs full meetings, lectures, and tutorials in the browser while asking remarkably little of the server it runs on. Every group gets its own page with video tiles, a user list, and a chat pane, and participants join from desktop or mobile browsers with nothing to install. Presenters share a screen or individual windows, stream a video or audio file straight from disk, and switch to blackboard mode when a slide needs resolution more than frame rate. Moderators can warn or remove participants and lock the group, raise-hand status keeps question queues orderly, and anyone can blur their background or exchange files directly with peers. Groups are simple configuration files: set public or private rooms, passwords or login tokens, client limits, and expiry windows, then create users with moderator or presenter privileges using the galenectl command. Automatic subgroups spin up identical breakout rooms on demand, the pattern its author uses to supervise forty students working in pairs during computer science practicals. Calls stay smooth on poor networks because the server adapts video quality per participant, recovers lost packets, and relays media through its built-in TURN server when firewalls block direct paths. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
