About thorium
From Modrinththorium is a fabric mod that fixes 50+ small bugs and annoyances in Minecraft.
thorium is a fabric mod that fixes 50+ small bugs and annoyances in Minecraft, without affecting gameplay mechanics.
Because thorium does not affect gameplay mechanics, it is not a hard requirement to have installed on the client or the server when joining a server. However, we still recommend installing it on both, since not all issues can be fixed on the server (or client) side.
If you have encountered an issue or would like to request a fix for a Minecraft bug, please create an issue on our issue tracker.
For support, check out our Discord or IRC Channels!
