Repetier-Server
What Repetier-Server is
Repetier-Server controls and manages 3D printers from Windows, Mac OS X, Linux, or a self-hosted setup. One installation can handle multiple printers, with capacity depending on available hardware. It offers 2D and 3D G-code previews, color-coded views, layer analysis, live print monitoring, and webcam viewing. Notifications can use Repetier-Informer, Pushover, WhatsApp, Signal, Telegram, or Facebook Messenger. MQTT systems such as Home Assistant and ioBroker can communicate with it, and event-triggered web calls are supported. User management assigns specific rights, while printer backup, restore, and a rescue system address some interruptions. Models, G-code, statistics, images, and videos remain on users’ computers. It can operate offline, although activation and automatic updates need internet access. Development has ended at version 2.0, which is free for everyone and needs no license.
