They can't take what isn't there.

Skelle Client is the first dedicated DonutSMP mob spawner protector.

We've put Skelle Client through extensive testing to ensure your spawners are protected while you're away. The moment a player puts your spawners at risk, Skelle's advanced detection system reacts instantly, mines your mob spawners, and safely banks them in your Ender Chest before they can be lost — 2,400 mob spawners in 30 seconds, with only 1 account.

Protect your farm. Protect your profit.

The problem

You can't go AFK, because you're trying to farm your spawners.

DonutSMP mob spawners are one of the most expensive things most players own. They sit in one place, and you have to be there when something happens.

01

Spawners are a fixed target

All your spawners are in one place, all in one area. You might have the obsidian box, but that only buys you time. It doesn't buy you safety.

02

It happens when you're gone

The chances of you being at your computer when someone comes are low. Other people come when you think you're in the clear, when you least expect it. But Skelle is always ready.

03

Hackers

If you've ever had a base on DonutSMP, you've probably been raided. And the person who raided you was probably a hacker. You might have a big box protecting your spawners, but there's always a hacker using ESP.

This is why you need Skelle, DonutSMP's only dedicated spawner pack-up client.

The run

What happens the second someone loads in

1

Sees them

Any non-whitelisted player loading in, at any range. Your friends and your own alts are ignored — they never trip it.

2

Locks itself out

Before a single block breaks, the account locks itself out. A crash mid-run can't reconnect it into a live raid.

3

Verifies Silk Touch

The tool in hand is checked before every swing. Wrong tool and it refuses to mine rather than destroy a spawner.

4

Takes the spawners

The whole section comes down. When the inventory runs short, shulkers open and packing continues — a run never stalls half-done.

5

Banks and leaves

Everything goes into your assigned Ender Chest, then a clean logout. Whoever's digging arrives at an empty hole.

6

Comes back and checks

It re-sweeps until a full pass finds nothing left standing, then re-arms itself and waits.

One run, start to finish — exactly what the steps above look like in the log.

Runs itself

Minimal work. Just leave it to the mod.

The failure cases are the whole product. Every one of these exists because guessing wrong costs you the farm.

Survives restarts

Server restarts and proxy limbo don't break it. It waits them out, verifies the farm is actually back, then re-arms.

Never reconnects mid-raid

It comes back after a restart. It never comes back after a pack-up — once the mob spawners are banked, the account stays off.

Accounts work as a team

Run several accounts on one farm. Each gets its own section and its own chest, and they treat each other as peers, not intruders.

A ledger, not a pile

Every spawner is recorded against the coordinate and mob type it came from — so the farm can be rebuilt exactly, from the record.

Refuses rather than guesses

It won't arm without room for the whole section. A half-finished run is worse than no run, so it says no instead.

Silk Touch, every swing

Verified in hand before each break. There is no path where it destroys a spawner because the wrong pick was equipped.

Access

Your mob spawners cost more than all of these

Lite works on all computers, uses minimal RAM, is easy to set up, and can easily run on a cloud computer of your choice. Full runs up to 4 accounts at once, so one farm can work several sections in parallel. Lifetime supports up to 6 accounts, with endless options, lasts forever, and costs less than three months of Full.

Prices are set and billed in USD.

Lite

One account, guarded properly. The essentials, nothing stripped from the core.
$5 /month

Obsidian box builder

Hand it a stack of obsidian and it walls the farm in for you — no more placing a box block by block at 2am.

In progress

Area digger

Clears a region down to whatever depth you set. Room for the farm, dug while you do something else.

FAQ

Frequently asked questions

A whitelist. Anyone you add — friends, your own alt accounts, teammates running their own section — is ignored completely and never triggers a run. Everyone else counts as a stranger the moment they load in.

The account locks itself out before the first block breaks, so a crash can't reconnect it into a live raid. On the next start it re-sweeps the section and picks up whatever is still standing.

On Full and Lifetime it waits out the restart or proxy limbo, verifies the farm has actually loaded back in, and re-arms itself. It reconnects after a restart — never after a pack-up. On Lite you re-arm it yourself.

Yes. Each account gets its own section and its own Ender Chest, and they recognise each other as peers instead of intruders. Full covers up to four; Lifetime up to six.

Every spawner is logged against the coordinate and mob type it came from, so the record is enough to rebuild the farm exactly as it was. Full ledger export is a Lifetime feature.

Skelle runs as a background client mod with no HUD and no render-heavy features, so the load is small. Exact impact depends on your PC and how busy the server is. Measured figures will be published here once testing is finished.

Once payments are set up you'll get a download and setup instructions here. That flow isn't live yet — this is a placeholder answer.

How long would it take you to grind those mob spawners again?

That's the number to compare against. Not $5, $10, or $25.
