SpawnFilter
by CozyStudios
SpawnFilter stops players from spawning on specific blocks, such as lava, water or magma, by blacklisting them on the server.
What it does
Modpack developers and server owners use SpawnFilter to make sure players do not spawn where they are not supposed to. The blacklist is configurable, so the server decides which blocks count as unsafe. Block tags can be used as entries, so a single tag such as minecraft:fire or minecraft:leaves covers every block in that group at once.
When a player would spawn on a listed block, the mod searches for a nearby safe position and moves the player there. The mod is server-side only, so players join without installing anything, and the server alone needs the Fabric loader. Files are published for Fabric across 16 release versions, 1.20.1 – 26.1.2, with 1.0.0 for 1.21.11 as the latest file. The code is not open source and is released under All rights reserved.
Key features
Configurable block blacklist
Server owners list the blocks where players must not spawn, such as lava, water or magma.
Tag support
Block tags such as minecraft:fire or minecraft:leaves can be listed to block a whole group in one entry.
Automatic safe spawn search
When a spawn lands on an invalid block, the player is moved to a safe position nearby.
Lightweight utility
The mod does one narrow job, keeping players away from dangerous or unwanted blocks, and adds little else to the server.

Use cases
Modpack spawn safety
Modpack developers can block spawn points that would drop players into lava or other hazards after a respawn.
Public servers
Server owners who want to keep spawns out of unwanted terrain can set the blacklist without changing the world.
Who it’s for: Modpack developers and server owners who want to control where players can spawn. Players who join a server running the mod need nothing extra installed.
How it compares
Death Back is also server-side only and open source under the CC0 1.0 Universal license, with files for 1.20 – 26.2, but it handles returning players to a death point rather than spawn blocks. Mob Blacklist is server-side only and open source under the MIT License for 1.21.1 – 26.1.2, and it filters mob spawns instead of block spawns. Custom Mob Spawns is open source under the MIT License for 1.19.3 – 1.21.1 and can run on the client, the server or both.
