HOPPEREvery client in sync, before the game starts.

Self-hosted mod sync for Minecraft. One list on the server, one jar in mods/, and nobody has to be told to update.

No restart

On Forge and NeoForge, mods download before the loader scans for them, so they load in the same launch.

Forge 1.12.2 through current, NeoForge, Fabric and Quilt, from one shared core and a thin adapter each.

The generated jar already carries its server's URL and token. Drop it in mods/ and it works.

Downloads land in hoppermods/, never in mods/. A jar HOPPER did not download is never deleted.
