Zone Cleaner
by DreykaOas
Zone Cleaner gives server admins a way to remove large areas of blocks and entities without freezing the server.
What it does
Zone Cleaner runs on the server and lets an admin clear a region of the world with a single command. Clearing is split into small pieces that run across server ticks, so removing a very large number of blocks does not drop the tick rate. The server monitors its mean spike per tick and sets the work budget for each tick, so a busy server gets less work per tick and an idle one gets more. Operations are set up with a position selection: a first and a second corner are saved, and then a block removal command runs over the area. Other commands clear a set radius around a point, drain an ocean between saved positions or clear a range from the world bottom to the top.
Removal avoids the side effects that come with plain block changes. Sand and gravel do not fall, water does not flow, and observers do not trigger. Light is recalculated in pieces, so removing a mountain does not stall the server while shadows are computed. An undo feature with a progress bar lets an admin reverse an operation, and the mod is published for 1.19.2 – 1.21.8 on Fabric, Forge and NeoForge. The code is open source under the MIT License.
Key features
Time-sliced removal
Large operations are divided into micro-tasks spread across server ticks, so the server keeps its 20 TPS.
Adaptive work budget
The mod reads the server's mean spike per tick and allocates less work when the server is busy and more when it is idle.
Position selection
Two corners are saved with pos start and pos end, then a removal command runs over the area between them.
Undo with progress bar
A progress bar tracks a running operation, and the undo feature can reverse a completed removal.
Side-effect suppression
Sand and gravel stay in place, water does not flow and observers do not trigger during removal.
CPU limit per command
A number added to the end of a command caps how much CPU power that task may use.

Use cases
Clearing a build site
An admin clears a 100x100 area down to a set height, such as stone at y=64, before building on it.
Draining an ocean
Saved positions mark the edges of a body of water, and the drain command empties the area between them.
Who it’s for: Server owners and administrators who need to remove large volumes of blocks on a running server. The mod is server-side only, so players join without installing it.
