This is a relay for Tor users to be able to access Tor (when normal guard relays (first hop in a Tor circuit) are blocked), using domain fronting and webrtc.

The text is written quite confusingly, at least the German translation it served me by default. I was wondering how this could circumvent censorship, as the target needs to also support webrtc so there's no way to access any http(s) website via this in-browser proxy, this still requires another server to accept the webrtc connection and forward your traffic, but the point (which the article doesn't mention) is to be able to connect to this other server indirectly.

It even goes so far as to claim that you don't need any software to visit censored websites:

> Im Gegensatz zu VPNs musst du keine separate Anwendung installieren, um dich mit einem Snowflake-Proxy zu verbinden und die Zensur zu umgehen.

Except you do. Without Tor client, this snowflake proxy is useless. Clicking through to the technical details (link marked with a warning "this content is in English"):

> 1. User in the filtered region wishes to access the free and open internet. They open Tor Browser, selecting snowflake as the Pluggable Transport.

The article said "contrary to VPNs, you don't need to install separate software to circumvent censorship" and the technical overview says the literal opposite: you need to install a Tor client to make use of a snowflake proxy.

I can't speak to the German translation, but the point the English version is making is you don't install Snowflake, you install software that uses Snowflake (most typically, Tor Browser). It's presumably trying to clarify things for confused users trying to figure out how to install Snowflake as a proxy or VPN application, when that's not how it works.

edit to add the direct quote (which seems pretty clear to me): "Unlike VPNs, you do not need to install a separate application to connect to a Snowflake proxy and bypass censorship. It is usually a circumvention feature embedded within existing apps."
