ChallengeTimer
by AAirCrafter
ChallengeTimer lets server owners run timers and stopwatches for challenge runs, with colored, animated and configurable on-screen text.
What it does
The mod adds advanced timers and a count-up stopwatch that can be used for speedruns, timed challenges and similar server events. Several timers can run at the same time, and each one can show its own text.
Timer text supports named colors, hex codes, static colors and animated gradients, with the animation speed and direction adjustable. Prefix and suffix text can be set, can inherit the formatting of the timer, and separate texts can be shown when a timer finishes or is paused.
Only the server needs the mod, so players join without installing anything. It targets Minecraft Java Edition 1.21.5 on Fabric Loader, and the latest file is 1.21all for 1.21.11. The mod is not open source and is covered by a custom license. Its first file was published on 2025-06-10 and the most recent update is dated 2026-09-20.
