Cobalt
A self-hosted Media & Streaming app you can run on your own server.
Cobalt is an open, self-hosted media and streaming application — you install it on your own hardware and keep full control of your data. Because it runs on infrastructure you control, your data stays with you and there is no subscription required to keep using it.
Its public repository on GitHub currently shows 42.8K stars, a useful signal of community interest. Repository activity was last recorded on Apr 6, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Media servers live or die by transcoding performance and library organisation. Check the hardware-acceleration support for your GPU or NAS, and test with a small library first. Most tools scan standard folder structures automatically, so tidy naming pays off quickly.
Like every project listed on SelfHosted, Cobalt is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
