SchemNexus
by tapter
Players who build large schematics can have SchemNexus save them automatically, using defined zones and a timer.
What it does
SchemNexus saves schematics on a schedule instead of by hand. A player defines schematic zones, and the mod stores each zone automatically whenever the configured timer fires. The saving runs on its own, so a build in progress is captured without the player stopping to save it.
The mod is written for Fabric and runs on 1.20.1 – 1.20.6 with the same feature set across those builds. Client and server both run it, so a dedicated server and the players who connect to it need the mod installed. The mod is not open source and is released under All rights reserved.
No additional mod is required beyond the Fabric loader itself, and the mod's own files cover six release versions in that range, with 1.0.3 for 1.20.6 as the latest. Snapshot builds are not part of its publishing record.
Key features
Automated schematic saving
Schematics are written to disk on a timer without any manual save step.
Defined schematic zones
A player marks the area each schematic covers, and only those zones are saved.
Configurable timer
The interval between automatic saves can be set, so the frequency fits the size of the build.
Scheduled, not one-time
Saves repeat over the session, so a long build keeps a recent copy as it grows.

Use cases
Long survival builds
A player constructing a large base over many hours can keep a running backup of each zone.
Shared server projects
Server owners running collaborative builds can keep automatic copies of the work in progress.
Who it’s for: Builders who use schematics heavily and want saves without manual steps, and server owners who run shared construction projects on Fabric.
How it compares
Schematic Market is a Fabric mod for 1.20.1 – 1.20.6 with the same client and server environment as SchemNexus, released under the MIT License. Book and Quick Save is client-side only, covers 1.20.4 – 26.1.2 and is under All rights reserved, so it does not need to run on the server.
