I found a Purpur server running on 1.21.11 and it is all about letting players use stasis glitches.
The main thing people ask about is getting the fishing rod stasis glitch working by changing the right lines in the yml files. This place feels like it is for players who like testing weird Minecraft mechanics and messing with server settings to make them possible.

GG.MINEWIND.NET New Server IPHost Your Own Local Minecraft Server
This is a Minecraft thing for people who want to run a server on their own computer.
It uses a control panel that feels really techy and clean. You can watch the console in real time and see everything the server is doing. You can also manage files yourself and make backups so you do not lose your world.
It works with modrinth modpacks so it is nice if you like messing with mods. It also tries to handle Java in a smart way so you do not have to fight with it as much.
The project is still getting fixed and improved so there might be bugs. The owner is open to feedback and issues and wants people to help make it better.GG.MINEWIND.NET New Server IP
