Crawly server crashes on startup – what to do?

Crawly officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.10, 1.21.9, 1.21.8. 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 Crawly – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Crawly consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
