I'm Fast
by Bielhiss
Players who want to move faster than vanilla allows can install I'm Fast on a server, which removes the game's speed limits for moved too quickly and moved wrongly checks.
What it does
The mod uses mixins to lift the vanilla checks that flag movement as too fast or wrongly moved, so players can travel beyond the normal limits. Only the server needs it; players join without installing anything. It is published for Fabric, Forge and NeoForge across 21 release versions, 1.18.2 – 26.3, and the code is open source under the MIT License.
Key features
Removed speed checks
Lifts the vanilla limits that flag movement as moved too quickly, letting players exceed normal walking and sprinting speed.
Removed wrong-movement checks
Stops the server from rejecting movement it considers moved wrongly, so the player's position is not forced back.
Server-only installation
Placed in the server mods folder and needs no client install, so players join without any change to their game.

How it compares
Just Enough Speed is also a server-side mod under the MIT License, but it is published for 1.0 – 1.20.1 and so covers older versions than I'm Fast. Frostbyte's Skip Server Movement Check is Fabric-only, server-side and not open source, with files for 1.21 – 26.3.
