Frequently Asked Questions

ModifyJS server crashes on startup – what to do?

Is ModifyJS compatible with forge and neoforge?

ModifyJS officially supports forge, neoforge for Minecraft 1.21.1, 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with ModifyJS – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if ModifyJS consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
