Polaris

Self-hosted, Linux-only GameStream host for streaming PC games to Nova and Moonlight clients.

Servicefreeglobal

Polaris is a free, open-source, self-hosted game streaming host for Linux that streams PC games to Moonlight and Nova clients without taking over the host's own desktop, using an isolated compositor runtime and GPU-aware capture. It's aimed at Linux users who want to self-host their own game streaming setup instead of relying on a commercial cloud gaming service.
