Entity Custom Data officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.4, 1.21.3, 1.21.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Entity Custom Data – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Entity Custom Data consumes the most tick time.
