Skybreaker
by needyimanbka
Skybreaker raises the vertical build limit of the Overworld, so worlds can be built higher than the vanilla ceiling.
What it does
Skybreaker removes the Overworld's vertical build limit, which stops at Y=512 in vanilla Minecraft 1.16.5 and at a higher cap in later versions. Players and builders get more room above and below the usual height range. Only new worlds are affected: a 1.17.1 or later dimension type is baked into a world when it is created, so existing worlds keep their original limit.
The mod is server-side only, so the server needs it and players join without installing anything. It runs on Fabric and Forge and has no required dependencies beyond the loader's own mod-loading setup. Files target 1.16.5 – 26.2 and the latest builds are 0.1.0 for 26.2. The code is released under the MIT License and is not open source.
Key features
Taller Overworld
The Overworld's height limit is raised, adding room for builds, terrain and new content above the vanilla maximum.
Worlds created after install
The raised limit applies only to worlds generated after the mod is installed, so old worlds keep their original height.
Chunk data handling
Chunks use a height network format that goes past the 32-bit bitmask limit of 1.16.5, which needs a packet format change.

Use cases
Tall builds
Builders who want towers or sky islands above the normal height range can use the extra space in a new world.
Deep mining and terrain
Extra vertical space below the usual bottom lets terrain and caves extend further in new worlds.
Who it’s for: Server owners and builders who start new Overworld worlds and want more vertical room than vanilla allows. Players joining such a server need nothing extra installed.
How it compares
Higher Heights is server required with the client optional, under the MIT License, and covers 1.17 – 26.3 on Fabric, Forge, NeoForge and Quilt. No Sky Limits covers 1.21 – 26.3 with a server-required, client-optional setup and is open source under the MIT License. Skybreaker differs by being server-side only, with no client-optional option, and by targeting 1.16.5 – 26.2 on Fabric and Forge.
