Simple Spawn Timer
by sloth_exe
Players who track timed mob respawns can use Simple Spawn Timer to run up to 999 named countdowns on screen, with Mob spawn tracking added on top.
What it does
Simple Spawn Timer is a Fabric mod that runs only on the client, providing on-screen countdown timers together with automatic tracking of mob spawns. Only the client needs it, so a server can run without it and players join without installing anything. Timers support seconds, minutes and hours up to 24 hours, and they keep counting in real time across game restarts.
Automatic detection watches a mob from the front field of view, including an X-ray check, and creates a countdown after a kill. Over time the mod records how long each respawn takes and moves each timer through the LIVE, countdown and UP phases, and several spawns of one mob type can be followed in separate locations at the same moment.
Alerts include full-screen warnings, a two-tone urgent alarm sound on spawn, red for live mobs and yellow for timer warnings. Timers can be reset with Ctrl or Cmd plus a slot number, which restarts slots 1 to 10 without opening chat. Click interactions on the HUD mute, reset or remove a timer, and the HUD itself can be dragged anywhere on the screen. The mod is open source under the MIT License and is published for 26.1.2 only, with the latest Fabric file 1.5.0 dated 2026-08-13.
