If you run a Minecraft server for a friend group or small community, you've probably noticed something frustrating: you're paying for a server that runs 24/7, but players are only online a few hours a day. The rest of the time, your server is sitting idle — burning compute, billing you, and doing nothing.
CraftCtrl's auto sleep/wake feature solves this problem entirely.
The Problem: Idle Servers Are Expensive
Let's say you run a modest community server on a typical cloud VPS — 2 vCPUs, 4 GB RAM. You're paying around $20–40/month. Your players are online from 6pm–10pm on weekdays and a few hours on weekends. That's roughly 30–40 hours per week of actual playtime out of 168 total hours.
You're paying for 168 hours but using 30–40. That's 75%+ waste.
A traditional hosting provider doesn't care. They charge you for the server whether it's full of players or gathering dust. CraftCtrl takes a different approach.
How Sleep/Wake Works
CraftCtrl uses an open source tool called lazymc to proxy incoming Minecraft connections. Here's the flow:
-
No players online — after a configurable idle timeout (default: 10 minutes), CraftCtrl hibernates the server. Kubernetes releases the CPU and RAM allocation. You stop being charged for compute. Your world data stays safely on disk.
-
A player tries to connect — lazymc intercepts the connection and shows a vanilla-compatible "Server starting..." message in the Minecraft client. This works with all standard Minecraft versions.
-
Server boots — CraftCtrl wakes the server, Kubernetes schedules the pod, and the JVM starts. On a typical Paper server, this takes 30–60 seconds.
-
Player is connected — once the server is ready, lazymc hands off the connection and the player joins normally. From their perspective, they waited ~45 seconds. They don't need to retry the connection.
The Numbers
Here's a real comparison based on a typical community server with 3–8 concurrent players, active 5–6 hours per day:
| | Traditional Hosting | CraftCtrl | |---|---|---| | Server hours billed | 720/month | ~180/month | | Estimated monthly cost | $35/month | ~$11/month | | Savings | | ~69% |
The exact savings depend on your community's activity patterns. Servers with shorter active windows save even more. A server with 3 hours of daily activity could see 80%+ savings.
What About the Wake Delay?
The 30–60 second wake delay is the main trade-off. For a casual friend-group server, this is completely acceptable — players understand the server needs a moment to start. Many communities have even turned it into a community ritual: "Server's booting, be there in a minute."
If you can't tolerate any wake delay (e.g., a competitive server or one with high population peaks), you can disable auto sleep/wake and run the server always-on. You lose the cost savings but retain all other CraftCtrl features.
On the Pro and Enterprise plans, you can configure the idle timeout and the minimum number of online players before hibernation triggers. You can also set "always-on" windows — for example, keep the server running between 5pm–11pm on weekdays even if it's empty.
Setting Up Auto Sleep/Wake
In CraftCtrl, enabling sleep/wake takes about 30 seconds:
- Open your server's settings in the dashboard
- Navigate to Lifecycle > Auto Sleep/Wake
- Toggle the feature on
- Configure your idle timeout (we recommend 10–15 minutes for most communities)
- Save
That's it. CraftCtrl handles the lazymc proxy configuration, Kubernetes pod management, and player connection handling automatically.
Monitoring Your Savings
The CraftCtrl dashboard includes a real-time cost tracker that shows:
- Active hours this billing cycle (billed)
- Sleeping hours this billing cycle (not billed for compute)
- Estimated monthly cost at current usage rate
- Historical savings vs always-on cost
You'll know exactly how much the feature is saving you.
Self-Hosting
CraftCtrl is fully open source under the MIT license. If you're running your own Kubernetes cluster, you can deploy CraftCtrl for free and get all the same cost savings without paying for managed hosting. See the self-hosting docs for a step-by-step guide.
Conclusion
Auto sleep/wake is the single most impactful cost reduction available to Minecraft server operators who don't need 24/7 availability. For a small community server, it can cut your monthly bill by more than half. For a collection of servers, the savings compound quickly.
