Stop guessing which mod broke your server.
Paste your latest.log or crash report. We tell you what failed and which mods
are involved — free, no account, and nothing is stored.
This page reads your log. The app fixes it.
Reading a log tells you what already went wrong. ModTamer for desktop boots your pack for real in an isolated copy, bisects which mod is responsible when the log is not enough, installs the dependencies it can defend, and verifies the result by booting it again. It never touches your server without a backup first.
- Isolate — finds the minimum set of mods that reproduces the crash
- Repair — resolves what it can prove, and says what needs a human
- Benchmark — TPS, tick time and per-mod cost under real world load
- Validate — catches mods that load but silently register nothing
- Updates — tests new versions before you apply them
- Migrate — tells you what you would lose moving to a new Minecraft version
Verified versions
These are the combinations ModTamer actually boots and checks, not a list we typed. Outside them it may work, but nobody verified it.
