Cobblemon: Generation Spawns
by DAN2026
Cobblemon: Generation Spawns limits which Pokémon generations can appear naturally in a world, and the Cobblemon mod it depends on handles the rest.
What it does
Generation Spawns lets a server owner turn individual Pokémon generations on or off for natural spawning, for example allowing only generations 1 and 8 to appear in the world. Changes are made with in-game commands and take effect without a server restart, so a server can adjust its spawn pool while players are online. The mod also offers debugging commands that report which generations are currently active and which are stored in cache or in persistent storage.
A new world can begin with natural Pokémon spawning blocked until an administrator enables generations, which suits tournaments, challenge runs or modpacks that restrict the Pokémon pool. A required dependency must be installed alongside it. Generation Spawns is server-side only, so players join without installing anything. Files are published for Fabric and NeoForge for 1.21.1, and the mod is released under All rights reserved, so it is not open source.
Key features
Generation filtering
Each Pokémon generation can be allowed or blocked for natural spawning, so the spawn pool matches the server's rules.
Live configuration
Generations are toggled with in-game commands, with no restart needed to apply the change.
Spawning blocked at first launch
A new world can keep natural spawning off until an administrator enables the generations that should appear.
Generation status reporting
Debugging commands show the active generations and the generations held in cache or persistent storage.

Use cases
Who it’s for: Server owners and modpack authors who want to control which Pokémon generations appear in a world. Players on a server that runs the mod need no extra installation.
How it compares
Cobblemon - Let Me Spawn is also server-side only and open source under the Mozilla Public License 2.0, for 1.21.1 on Fabric and NeoForge, so it covers a different spawning rule.
