Steam Link, whether in hardware or software form, supports the streaming of content from a personal computer running Steam to the video device (a connected television or monitor for the hardware unit, the mobile device's screen for the software version).

[9] Valve announced in November 2018 that they are no longer manufacturing the Steam Link hardware device, and will sell off the remaining stock.

Valve will continue to support software and device updates to existing Steam Link hardware, but are directing users towards the mobile app to provide the same functionality.

[14] In December 2018, Valve released a Linux version of the Steam Link software for ARM architecture, targeting Raspberry Pi 3, 3 B+, and 4.

On Meta Quest Pro, eye and facial tracking data can also be transmitted to VR software using OSC.

The software competes primarily with the Meta Quest "Air Link" feature, and third-party app Virtual Desktop.
