Fiw Clock
by Fi3w0
Fiw Clock is a server-side Minecraft mod that quietly records each player's playtime, kills, deaths and other stats into a JSON file per world.
What it does
Tickwatch tracks one integer per online player on every tick and writes the results to fiw-clock/stats.json without blocking server disk writes, since saving runs on a dedicated background thread. Players who sit AFK stop earning playtime, and AFK time is excluded from the total, so idle accounts cannot farm either figure. Optional milestone broadcasts can announce achievements such as a player reaching 100 hours.
Players join with a vanilla client, so nothing needs to be installed on their side. The server build covers Fabric, Forge and NeoForge across the 1.20.1 and 1.21.11 game versions, with files for 1.20.1, 1.21.1 and 1.21.11, and is released under the MIT License as open source. Fabric API, Fabric Language Kotlin and Kotlin for Forge are required, and LuckPerms is optional for syncing stats into its meta info.
Key features
Playtime and AFK tracking
Playtime is counted per player, and time spent AFK is left out of the total.
Kill and death counters
Kills and deaths are recorded alongside playtime in the same stats file.
Background saving
Writes to the JSON file happen on a dedicated thread, so the main server loop is not held up by disk work.
Milestone announcements
Optional broadcasts announce player milestones, such as a set number of hours played.
LuckPerms meta sync
With LuckPerms installed, the recorded stats can be exposed through its meta info command.

Use cases
Playtime on a shared server
Server owners who want to see how long each player has been online can read the totals from the stats file.
Rewarding activity
The stored kill and death counts can serve as a basis for in-game recognition or ranking by a separate plugin or script.
Who it’s for: Server owners who want playtime and simple combat statistics recorded without changing what players install.
How it compares
Simple Playtime Command is a Fabric-only mod for 1.21.3 – 1.21.10, and it works on either side, with neither side required, and it is not open source under the MIT License. Idler is server-side only, open source under the MIT License, and published for Fabric, Forge, NeoForge and Quilt across 1.20.1 – 1.21.1. Tab Info needs the server and is open source under the GNU Lesser General Public License v3.0 or later, with a client that may stay optional.

What the author says
Track playtime, AFK time, sessions, player & mob kills, deaths and kill streaks — server-side, lightweight, crash-safe, LuckPerms-ready. Tickwatch quietly records how long each player has played (AFK time excluded) and how many kills and deaths they rack up, then stores it all in a clean JSON file. No client mod…
