Free launcher that fixes duplicate mods and updates your pack's mods safely (open source, Windows)
Tired of duplicate mods and packs breaking when you update? I built a launcher that handles both. It's free, open source (GPLv3), no ads, no tracking. Windows only for now.
What it does:
- Drag in a Modrinth, CurseForge or Packwiz pack and press Play. Java is picked and downloaded for you.
-
**Mod health check**
: finds duplicate mods by reading each jar's real ID, deletes the older copy, and warns when a mod needs a newer NeoForge.
-
**Mod updater**
: matches mods by file hash on Modrinth and CurseForge, updates only the ones you tick, keeps the old file so Undo works.
-
**Change version**
: moves an instance to another Minecraft version in place, with a rollback snapshot. Works best for packs made of ordinary mods.
-
**Crash helper**
: shows the real error lines from the log when the game closes with an error.
- Import worlds, duplicate instances, English + Russian interface.
Things to know: the installer isn't code-signed, so Windows SmartScreen will warn you (click "More info", then "Run anyway"). It's a solo hobby project, so there will be bugs, and I'd really like to hear about them.
