ChunkReroll
by grateloup
ChunkReroll replaces the terrain of a chunk with one randomly chosen block type, and each chunk can be rerolled only once unless the server allows infinite rerolls.
What it does
Players who want a fresh landscape on a server-side world can reroll a chunk so that its natural terrain gives way to a single block type picked at random. The reroll changes a chunk only once by default, and the mod keeps the vertical limits set in its configuration, from y -64 up to y 319. Existing chests are never replaced, and the mod leaves end portal blocks and frames alone.
The mod is built to keep the world stable. Redstone and ticking blocks, falling blocks, trapped chests, shulker boxes, barrels, hoppers and spawners are on its protected list, and water and lava can be allowed or excluded through configuration. A per-tick block limit keeps the work spread out so a reroll does not stall the server. Installation needs Fabric. ChunkReroll is published for Fabric and also for the Paper, Spigot, Bukkit and Purpur server platforms. The code is under All rights reserved, so the mod is not open source.
Key features
Single reroll per chunk
A chunk is modified only once by default, and the mod can be configured to allow farming infinite rerolls instead.
Protected blocks
Chests, trapped chests, shulker boxes, barrels, hoppers, spawners, redstone and falling blocks are kept out of the replacement.
Configurable vertical range
The replacement is limited to a height band set in the configuration, with defaults from y -64 to y 319.
Per-tick block limit
Replacement work runs in capped batches of blocks per tick, which limits the lag a single reroll can cause.
End portal safety
End portal blocks and frames are protected, so the mod does not disturb the route to the End.

How it compares
No Portals is server-side only, open source under the GNU General Public License v3.0 only, and published for Fabric and Quilt across 1.19 – 26.3, so it covers portals rather than chunk terrain. Random Respawn is server-side only and open source under the MIT License, targeting 1.19.2 – 1.21.1 on Fabric, and changes where players respawn. Instant Chunks is server-side only, open source under the CC0 1.0 Universal license and limited to 1.20.5 – 1.20.6 on Fabric.
