Purely Beta
by Optim00se
Purely Beta turns a 1.21 world into a recreation of an early Beta-era survival game through a server datapack and resource pack, so only the server needs the mod.
What it does
Installed as a server datapack and resource pack, Purely Beta removes modern blocks, mobs, items and recipes and restores an older food system. Experience, hunger, attack delay and sprinting are removed, and the End is taken out as well. The mod's own text stresses reading the full page, since several key changes affect how the game plays.
Required mods are named on the page and must be installed alongside it. The author suggests the OldGenerator plugin for world generation, and notes that Golden Days Beta Recipes is integrated within EOB. The mod is published for Fabric, Forge, NeoForge and Quilt, and for the Data pack server platform, across the game versions 1.21 and 1.21.1. It is released under the MIT License and is not open source.

Use cases
Server-hosted Beta play
Server owners who want a Beta-style survival world install the datapack and resource pack on a 1.21 or 1.21.1 server, and players join with no mod.
Who it’s for: Server owners running a 1.21 or 1.21.1 world who want an early Beta style survival experience. Players need only the resource pack, since the mod is server required and client optional.
How it compares
No Sprinting removes sprinting on the server side, is open source under the MIT License, and is published for Fabric, Forge, NeoForge and Quilt across 1.21.2 – 1.21.8. Beta Days runs on both client and server for Forge and NeoForge across 1.19.4 – 26.1.2 under All rights reserved and is not open source. Just Beta Nether is server-side only for Fabric, Forge, NeoForge and Quilt across 1.20 – 1.21.1, under the MIT License, and is not open source.
