Valve's Steam Link hardware might be dead, but Steam Link as a service is getting a pretty major upgrade. There's no indication on when Steam Link Anywhere might roll out of beta and into full release, but since Valve says this is an early beta, that'll probably take some time.
Valve is launching Steam Link Anywhere, a new feature for its streaming app that allows users to connect to their computers and play games from anywhere, it announced on Thursday. For those playing games instead of making them, Steam Link is now officially usable outside of home networks, albeit in open beta. Initial compatibility with PCs running the Steam client software was expanded by the creation of a dedicated low-priced microconsole dubbed the Steam Link in 2015, pre-installation on selected smart TVs in 2016, and finally Android and iOS mobile devices in 2018.
The update is set to hit Steam Link hardware and apps today, though it'll require users to opt into a beta build dated March 13 or later.
Steam Link Anywhere, by contrast, has no such restriction: With a name that again leaves little to the imagination, Steam Link Anywhere effectively replaces Steam In-Home Streaming and allows for games and other software to be streamed from any network to any other network - including, potentially, mobile devices on a cellular network.
For now, said gaming devices are limited to the original discontinued Steam Link plugged into a TV via HDMI, Raspberry Pi and Android devices. After that, follow the simple instructions laid out here to get started.
As a software successor to the original Steam Link hardware that Valve killed off at the end of previous year, Steam Link Anywhere allows you to stream any game from your Steam library to whichever of those aforementioned devices you choose. Part of this is better development tools, but more importantly, Valve are letting developers route network traffic through Steam's own infrastructure now.
