Combat Tracker
by builtdoor
Combat Tracker is a client-side Fabric mod that records fights and turns the numbers into reports players can share.
What it does
Once installed, the overlay sits in the top-left corner of the screen and shows running combat stats while the player fights. A recording starts and stops with a key that is bound by default to J for showing or hiding the overlay, and recording is started from the mod's own keybinding under Options, Controls. When recording stops, the mod writes a session HTML report and a raw JSON file to the recordings folder, and a chat message gives the file path with a copy-link option.
The mod requires Fabric Loader 0.19.3 or newer and runs on Minecraft 1.21.11, and the game versions it targets span 1.21.1 – 1.21.11 across four release versions, with files for 1.21.1, 1.21.4, 1.21.8 and 1.21.11. The latest Fabric file is 1.10.4 for 1.21.11, released 2026-08-14. Only the client needs it. Combat Tracker is released under the MIT License and its source code is public.
Key features
Live combat overlay
A compact or full overlay shows running stats during a fight, and it can be hidden with a key.
Variance indicator
The variance line changes colour from white to red when clicking barely varies, which the author describes as a bot-like pattern.
Recording session
A red REC timer appears when recording is active, and stays grey until enough hits have landed for the numbers to mean anything.
HTML and JSON reports
Each session produces a full HTML report with four charts and a raw JSON file with the underlying numbers.
Interactive charts
In the report, clicking a point shows its exact value, and scroll, drag and double-click control zoom, pan and reset.
