Joinqueue
by epicskydex
Joinqueue holds players in an orderly queue when many of them try to log in at once, so a busy NeoForge server stays responsive during mass logins.
What it does
Joinqueue is a NeoForge mod. Its queue is thread-safe and admits players at a steady rate instead of letting every login compete at the same moment, which is meant to prevent crashes and TPS drops during mass logins. The mod is required on both the server and the client, so each side needs its own copy, and the environment is client and server.
Joinqueue runs in three activation modes: it can stay active by default, activate only above a set number of online players, or force itself on for a grace period after a restart, with 60 seconds as the default. Queue release pauses when server TPS falls below 8.0 and resumes once the server stabilizes. Release timing is set in ticks between joins, with a default of 2 seconds for normal players and 1 second for VIPs. Async chunk loading preloads spawn chunks on background threads before a player joins, with a configurable radius that defaults to 3.
The mod is released under All rights reserved and is not open source. Files are published for 11 release versions, and the latest NeoForge file is version 3 for 1.21.11, dated 2026-07-22.
Key features
Thread-safe login queue
Players are held in a queue and released at a stable rate, which limits the load that mass logins place on the server.
Automatic TPS pause
Releasing stops during heavy lag and resumes once server TPS returns to a stable level above 8.0.
VIP and staff priority
VIP players move to the front and are released on a faster timer, while staff members bypass the queue entirely.
Admin commands
Admins can pause, resume, start, stop or toggle the login process with commands, and a custom position screen is included.
