Plugin ProtocolSupport

ProtocolSupport, cross version access for your Minecraft server

ProtocolSupport is a Spigot plugin that lets players using Minecraft clients from 1.17 down to 1.4.7 join a single 1.17.1 Minecraft server. It works by translating network protocols in real time, so older clients can connect without changing their game installation, perfect for communities with nostalgic players or mixed setups.

Server owners gain flexible version support while keeping one stable server core, instead of running many parallel instances. Some very old clients may miss cosmetic details, but gameplay remains smooth and fully compatible, which is exactly the kind of experience we like to deliver at BoxToPlay.
