Tick Stasis
Running a Minecraft server around the clock can waste resources when nobody is playing. The Tick Stasis add-on elegantly solves this by pausing the entire server tick loop the moment the last player leaves, then seamlessly resuming it when someone joins again. This lightweight Fabric mod keeps your world frozen in time, prevents unwanted changes, and slashes CPU consumption to near zero, all without interrupting console commands or administrative tasks.
What Is Tick Stasis?
Tick Stasis is a server-side Fabric mod that automatically halts all game updates when no players are connected. Unlike simply idling, where the server continues to process block ticks, entity movement, and random events, Tick Stasis puts the entire simulation on hold. This means crops won't grow, redstone circuits won't fire, and mobs won't wander or despawn while you are away. The moment a player logs back in, the server picks up exactly where it left off, with no catch-up lag or time skips.
How Tick Stasis Works
The mod hooks into the Minecraft server's tick loop and monitors player count. When the last player disconnects, Tick Stasis suspends all world processing. In-game time stops, so the local difficulty multiplier never increases during empty periods. Console commands remain fully functional, allowing operators to manage the server, run backups, or adjust settings without waking the world. As soon as a player begins to join, the mod instantly restores normal ticking, making the transition invisible to users.
Server Pause Mechanics
While paused, the server stops updating blocks, entities, and tile entities. Random ticks, scheduled ticks, and chunk loading are all suppressed. This prevents any unintended changes to your builds, farms, or redstone contraptions. The world's day-night cycle and game rules are preserved, so you won't return to find your base overrun by mobs that spawned while you were offline.
CPU Usage Reduction
Starting with Tick Stasis version 1.1.0, the mod reduces server CPU usage to 0% or near-0% when no players are online. This is a significant improvement over earlier versions and makes it ideal for small community servers or single-player worlds opened to LAN. By eliminating idle processing, you can host a server on modest hardware without worrying about constant background load.
Version Compatibility and Loaders
Tick Stasis is built exclusively for the Fabric mod loader. Version 1.1.0 supports Minecraft 19w11a and all later releases, including 1.14 and beyond, as well as snapshots and even April Fools' updates. The earlier 1.0.0 release covers 19w04a through 23w51b, which includes Minecraft 1.14 to 1.20.4. If you are looking for a newer version of Tick Stasis for Minecraft, check Modrinth, where the developer publishes the latest builds. The mod's open-source nature under a permissive license means anyone can attempt to port it to other loaders or older game versions.
How to Install Tick Stasis
Installing Tick Stasis is straightforward if you already run a Fabric server. First, ensure you have the Fabric loader installed for your target Minecraft version. Then, download Tick Stasis from Modrinth or CurseForge and place the JAR file into your server's mods folder. Restart the server, and the mod will activate automatically. There is no configuration needed; it works out of the box. If you prefer a more streamlined experience, the foxygames.net launcher includes Tick Stasis in its add-on catalog, allowing you to install it with a single click and keep it updated automatically alongside your other mods.
Frequently Asked Questions
Many server owners wonder about updating Tick Stasis to newer Minecraft versions. The developer recommends trying the latest mod release even if your specific version isn't listed as supported, because the mod often works across a wide range of snapshots and minor updates. If you encounter a crash or incompatibility, you can report it through the mailing list mentioned on the project page.
Porting Tick Stasis to older Minecraft versions or to other server platforms like Forge, Bukkit, Paper, or Spigot is not officially planned.
