About this Mod

Harmony is a library that tries to simplify mod creation. It has shortcuts to simplify things and has helpers to register generally, do translations, tweak UI, do item and stack behavior, handle NBT data, handle user messages, use mod identifiers in a generic way, schedule timers on tick, do mod files management, advancements and more!

Make sure to read the source code in the repository if you're interested to mess with it.

Frequently Asked Questions

Harmony server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.4). You can switch loaders with one click in the panel.

Is Harmony compatible with fabric?

Harmony officially supports fabric for Minecraft 1.20.4, 1.20.3, 1.20.2. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Harmony – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Harmony 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.
