All modpacks
MinecraftPurpur1.21.1Vanilla+Performance
Purpur
Purpur is the most-used Paper fork. Adds extensive config for tweaking vanilla mechanics (mob behavior, drops, world gen) without writing a plugin. Recommended for admins who want fine control.
Server flavor — not a modpack
You get a vanilla Purpur Minecraft server, ready for plugins (Paper/Purpur) or mods (Fabric). Nothing pre-loaded beyond the server itself.
