Flex Auto-Sleep vs Always-On: Which Plan Should You Pick?
Flex plans pause your Minecraft server after a few idle hours so you only pay for active time; Always-On runs 24/7. Here is how to choose so you do not overpay — or get caught with a sleeping server.
The single biggest factor in what you pay is not the game or the RAM — it is whether your server runs all the time. Quantum Shell offers two modes, and picking the right one usually saves money without hurting the experience.
Flex (auto-sleep)
A Flex server pauses itself after a few hours with no players online. While it sleeps, its world is snapshotted to secure storage and the underlying compute is fully released — so you are not paying for a machine that is doing nothing at 4am.
To play again, start the server from your dashboard — one click. It restores your latest world and is back online in about a minute.
Don't want to be the only one who can start it? Each Flex server has a shareable wake link you can pin in your group's Discord. Anyone who opens it can start the server (and only start it) and grab the connect address — no login needed. You can regenerate or disable that link anytime from the dashboard.
- Best for: friend groups, evening/weekend play, seasonal worlds.
- Trade-off: it is not running 24/7. Someone (you, or a friend via the wake link) starts it before a session — it does not yet wake up on its own when someone tries to connect, so the very first person can't "just join" a sleeping server.
Sleeping is not "off", it is "parked": your world is snapshotted before the server stops, so you never lose progress. Starting it again restores that snapshot automatically.
Flex is currently available for Minecraft only. Other games (Valheim, Project Zomboid, Terraria) run on Always-On plans.
Always-On
An Always-On server runs 24/7. It is ready instantly, every time, and is the right call when people might join at any hour or you run anything that must keep ticking when no one is watching.
- Best for: public servers, large communities, anything with scheduled events, or worlds with always-running automation.
- Trade-off: you pay for full-time compute even during quiet hours.
Quick decision guide
| Your situation | Pick |
|---|---|
| A few friends, mostly evenings | Flex |
| Public/community server, random hours | Always-On |
| You hate the wake-up wait | Always-On |
| You want the lowest bill | Flex |
| Automation/redstone must run overnight | Always-On |
How to switch
You choose the mode when you create a server, and you can change plans later from the dashboard. Billing adjusts from the next cycle — see the free Minecraft tier guide for a zero-cost way to try Flex behavior first.
