TPSChecker
by MrOrdenador
TPSChecker lets server administrators measure a server's lag through commands, reporting how smoothly the server is ticking.
What it does
Server owners and staff can check how a server is performing without leaving the game, using commands the mod registers. The readout helps narrow down whether slow play comes from the server rather than a player's connection. The mod is server-side only, so players join without installing anything and only the server needs it.
The mod is published for Fabric and needs Fabric API, which is not listed as a required dependency in this catalog entry. Its single file targets 1.21.5, released 2025-06-23, under the MIT License, and the code is not open source.
Key features
Lag checks by command
Commands report the server's tick performance, so staff can see lag without external tools.
Server-side operation
Everything runs on the server, and clients need no changes to use the commands.
Performance reporting
The readout gives server staff a concrete figure to compare across moments of slow play.

How it compares
FlowHud is a client-side HUD option for Fabric, published for 1.21.1 – 1.21.11 under All rights reserved and not open source. Memory Check is a server-side Fabric mod for 1.19.2 – 26.3 under the GNU General Public License v3.0 only, and it is open source, so it covers a different part of server monitoring.
