Viper Proxy
Viper Proxy, a Fabric mod for the client, sends multiplayer connections through proxy servers that the player configures.
What it does
Once a proxy profile is set up, the mod routes each multiplayer connection through the configured proxy server, so the server a player joins sees the proxy address rather than the player's own. Only the client needs the mod. Servers do not install it, and players join them the same way they would without it.
Setup happens on the Multiplayer screen, where a button in the top right opens the proxy configuration. Several proxy profiles can be saved and switched between from that screen, and each one can be tested before use. The mod supports SOCKS5, HTTP and HTTPS proxies.
Minecraft 26.2 is the target, and it needs Fabric Loader 0.19.3 or later, Fabric API 0.153.0+26.2, plus Java 25 or later. Its files exist for 1.21.10, 1.21.11, 26.1.2 and 26.2, and it is released under the MIT License as open source. Credentials are stored encrypted on disk and tied to the machine, so they are not kept as plain text in the config files.
Key features
Proxy routing
Multiplayer connections are sent through the proxy server selected in the configuration.
Built-in kill switch
Server connections are blocked entirely while the proxy is not healthy, so traffic does not fall back to the direct route.
Background heartbeat
A check runs every 15 seconds, and a proxy that drops mid-session is caught immediately.
Multiple profiles
Several proxy profiles can be saved and switched between from the configuration screen.
Encrypted credentials
Proxy login details are encrypted and tied to the machine they were saved on.

How it compares
RotProxy is also a client-side Fabric mod, released under the MIT License as open source, with files for 1.21.10 – 26.2. Viper Proxy covers the same client-side routing, adds a kill switch and a heartbeat check, and lists its own build range of 1.21.10 – 26.2 as well. PROXY protocol Wrapper is server-side only and open source under the GNU General Public License v3.0 or later, so it runs on the server side instead of the client.
