NekoFabricHacks
by ZhuRuoLing
NekoFabricHacks is a Fabric utility mod that makes Fabric's startup logging more verbose, covering mod entrypoints and Mixin configuration.
What it does
The mod turns on extra log output during game startup. Players and developers who need to know which mod entrypoints were loaded, or how Mixin configs were chosen and applied, can read that detail in the log instead of guessing. The author lists it as a set of small debugging helpers, and the mod is categorized under Utility with a Cursed tag.
Mixin is the bytecode layer that many Fabric mods use to change the game. When the log reports which config plugins were loaded and which Mixin changes were applied, troubleshooting a conflict becomes more direct. The mod works on the Fabric loader only, and both the server and the client can run it without other requirements.
Files cover 1.20 – 1.21.5 across 13 release versions, with 1.1.0 for 1.21.5 as the latest Fabric file, published 2025-05-19. The mod is released under the MIT License and is open source, with a public source repository and issue tracker. It was first published on 2024-03-23.
Key features
Entrypoint loading log

Mixin config plugin log
Reports which Mixin config plugins are selected and loaded, helping trace where a Mixin config comes from.
Mixin apply log

Verbose log messages

Use cases
Diagnosing a startup crash
When a modpack fails at launch, the extra entrypoint and Mixin lines show which mod or config step was reached last.
Checking Mixin conflicts
Developers testing two Mixin-based mods can compare the apply messages to see which change wins.
Who it’s for: Modpack makers, mod developers and players who need detailed startup logs to track down a failing Fabric setup.
How it compares
Early Loading Screen is client-side only and works with 1.19.2 – 1.21.4 on Fabric, released under the MIT License and open source. It shows a loading screen rather than adding log detail. Meteorite Client is also client-side only and covers 1.20 – 1.21.8, but it is not open source and is a large client mod with its own feature set.
