Modkeel Companion

Tells you which mod crashed Minecraft, with the evidence from the crash, and turns it off in one click. Backs up your world before you update the modpack. No mixins; the crash stays on your PC unless you choose to share it.

What's new

Two mods that can't be used together

  • NeoForge and Forge: when two mods include the same piece of code, the game would close before loading any mod. Modkeel now sees it before the game starts, turns one of them off so you can play at the first try, and says which in plain words. One button swaps which of the two stays on; the technical reason is under Details.

Warnings that matter, on one screen

  • Graphics: Modkeel notices when Minecraft draws without a graphics driver, or on the slow built-in graphics while a faster NVIDIA or AMD card sits unused. On Windows, one button switches Java to the fast card.
  • Memory: Modkeel notices when Java was given too little memory for the number of mods you have, nearly all of your computer's, or runs as 32-bit Java. It says the size to set and where your launcher keeps it (Prism, CurseForge, Modrinth App, Minecraft Launcher).
  • The Modkeel screen fits any window without scrolling: with several warnings, one stays open and the others take one line each.

Fixes

  • The loader's own parts (modlauncher, FML) are never blamed for a crash.
  • Lab data refreshed for 1.20.1, 1.21.1 and 1.21.11.
