How it works

Quasar runs games on your GPU server and brings them to your browser. A first install puts everything on one host; you can add another computer as your library grows.

QUASAR / CONNECTIONSOne host. Two paths.
Quasar all-in-one architectureThe browser uses HTTPS to communicate with the control plane, which manages sessions on the GPU host. WebRTC video, audio and input connect the browser directly to the GPU host over LAN or VPN.YOUR SERVERAll-in-one installHTTPSWeb app & APISessionmanagementDirect WebRTCVideo · audio · inputOver your LAN or VPNYour browserBrowse your library · press PlayControl planeAccounts, library & host selectionGPU hostNode agent · game & stream

Follow the request, then the direct stream.

Management goes through the control plane. The game stream connects your browser directly to the GPU host.

Press Play

Section titled “Press Play”
  1. Your browser asks the control plane to start an app.
  2. The control plane selects an available GPU host and compatible stream settings.
  3. The host’s node agent starts the game.
  4. Your browser connects directly to that host for video, audio and input over WebRTC.

The web app uses the control plane’s API for accounts, the library and session management. The direct host connection carries the stream, so every GPU host must be reachable from your browser over your LAN or VPN.

What runs on your server

Section titled “What runs on your server”
  • Control plane: serves the web app and manages accounts, the library and sessions. Its data lives in Postgres.
  • Node agent: runs apps and streams them from a GPU host. Each additional GPU server has its own agent.
  • Installation and recovery: you declare one seed container. It keeps a recovery service running to install, update and recover that machine’s Quasar services. Persistent machine state and user homes must be kept.
