Voxy Server
by PooSmacker
Voxy Server, a Fabric server-side mod, voxelizes loaded chunks into Voxy's LOD format and streams them to connected players who run Voxy.
What it does
Each chunk the server loads is converted into Voxy's LOD format, and the result is saved to a database that belongs to that world. Voxy Server scans the world only as far as chunk loading requires, and explored terrain from before the mod was installed can be backfilled from region files with an admin command, without players having to revisit those chunks.
A player with Voxy and Voxy Server installed receives LOD sections automatically as they connect, starting near the player and spiraling outward, with new sections sent as the player moves. Players without Voxy are unaffected. Clients also need Voxy Sodium alongside Voxy Server, and the mod requires no other server-side dependencies. Files are published for Fabric only, across five release versions, 1.21.11 – 26.2, and the source code is released under the GNU Lesser General Public License v3.0 only.
Key features
Chunk voxelization
Loaded chunks are converted into LOD data and stored in a database kept per world, under the voxyserver folder.
Streaming limits
Operators set the radius around each player, how many LOD sections are sent per tick cycle, how many are bundled into one packet, and the number of worker threads.
Live block updates
When a block changes, the server notices it and revoxelizes only the LOD sections that cover the change, then sends them to every connected client.
Client configuration
With ModMenu and Cloth Config installed, players open the Voxy Server config screen to adjust personal streaming preferences, capped at the server's maximums.
Regenerable data
The stored LOD data can be safely deleted, and it is regenerated from the world as chunks are loaded again.
Compatibility
Latest build for each game version and loader.

How it compares
WynnLODGrabber is client-side only, open source under the MIT License, and covers 1.21.1 – 1.21.11, so it runs without any server involvement. Poxy is also client-side only and open source under the GNU General Public License v3.0 only, with files for 26.1.2 – 26.2. Voxy Server differs in being server-side, streaming LOD data from the server to clients.
