Game servers that turn off when empty: Minecraft, Rust

Yes, several game servers switch themselves off when nobody is playing, but nearly all of them are Minecraft, and only some also wake by themselves when a player joins. Minecraft Java can pause its own game when empty, free software can stop and restart a server for you, and a handful of hosts do it as a service. For Rust, nothing is built in, and the pay-per-hour hosts we read still make you press Start. Everything below was read on 2026-10-04 from the vendors’ own pages. We looked at Minecraft and Rust only; other games are not covered here.

Minecraft Java: the built-in pause

Since development build 24w33a (15 August 2024), Minecraft Java servers have a server.properties setting called pause-when-empty-seconds. Mojang’s note says that when it is set to a positive value, the server pauses once no player has been online for that many seconds; the default is 60. It shipped in the 1.21.2 release (22 October 2024). Our reading, not Mojang’s wording: this pauses the game, but the program keeps running and keeps its memory. So it lowers the work the server does while empty, and on a host that bills for the memory a server holds it may not lower your bill. It needs no outside tool, and no wake-up step is described: the first player to join should simply resume it.

Minecraft on your own machine: lazymc

lazymc is a free open-source program (GPL-3.0) from timvisee. Its README says it puts your Minecraft server to rest when idle and wakes it when players connect, by sitting in front of the server and answering the server list itself until the real server has started. It can hold a joining player until the server is ready, or send a “starting” message. Its README lists Java Edition 1.20.3+ under features (its requirements section says 1.6+), and says you need access to the machine to run it, so it will not work on a shared host with a custom dashboard. Its latest tagged release is v0.2.11 from March 2024; the code was still being updated in July 2026.

Hosted sleep, who wakes by itself

Option	Game	When empty	How it wakes
Minecraft built-in setting	Minecraft Java	Game pauses	A player joining should resume it (our reading)
lazymc (self-run)	Minecraft Java	Server is stopped	Automatically, on a player connecting
Aternos	Minecraft	Server stops	Start button, with a queue when full; automatic only if you join through its own Dawn launcher
Minehut	Minecraft	Server sleeps	Automatically when a player joins
exaroton	Minecraft	Optional automatic stop	Optional “start by joining” setting, or the panel button
VoxelRun	Minecraft	Idle auto-stop	Automatically on join; also a share link with one button
Eytak	Minecraft	Server sleeps	Automatically, from the player’s server list
PowerupStack	Minecraft, Rust	Optional automatic shutdown	Minecraft: start by joining. Rust: its page describes switching it off yourself
RespawnHost	Rust and others	You stop it yourself	You start it from the panel
Arcadyo	Rust (private beta)	Sleeps at zero players	Wakes when a player connects (private beta; success rate still being measured)

We read RespawnHost’s Rust page and PowerupStack’s Rust page for the Rust rows. We did not check every other host, so a host missing from the table is “not looked at”, not “no”.

Rust: why sleeping is harder

Rust has no setting like Minecraft’s, and two things make sleeping hard. First, the game does not wait long: in our tests a Rust client stopped trying a server that had not answered within about five seconds, so a sleeping server has to be answering almost at once when the first player connects. Second, a running Rust server keeps a live connection to Steam, a bit like an open phone line, which is how Steam confirms the players joining are who they say they are. Pause the server and that line goes quiet; in our own tests it was usually gone after about half a minute, and calling back took from a few seconds to, in some runs, well over a minute. A friend who joins while the line is down can be turned away by Steam’s check. Arcadyo is built around these two problems. It is in private beta, and we do not publish a success rate yet. How Arcadyo works.

On the two pay-per-hour Rust hosts we read, you stop the server yourself and start it again. PowerupStack lists an 8 GB Rust server at €0.0795 per online hour, with a monthly maximum of €19.36, VAT included (read 2026-10-04). RespawnHost bills per second while the server runs, from a €5 top-up (its home page); its pages do not state VAT.

Arcadyo, in one paragraph

Arcadyo is a private beta for Rust groups. The server sleeps when nobody is playing and wakes when a player connects, at the same address and with the same world. The beta is free for the first 20 groups, up to 40 awake hours a month. It is early: we are measuring joins after a sleep with a real Rust client, and we will not quote a success rate until the measurements support one. Minecraft is being tested, not offered. If you want to size a Minecraft server meanwhile, our Minecraft server RAM calculator is free.

What we could not verify

Most of these hosts’ pages do not state VAT, we did not look at any host not in the table, and we did not check how lazymc behaves with the newest Minecraft releases. Treat those as open.
