HotProperties
by Fayber
HotProperties lets server operators change server.properties values on a running server, without a restart.
What it does
Because HotProperties saves each change to the file itself, the new value still applies after the server restarts. Settings such as view distance, simulation distance, the MOTD and the idle timeout apply immediately. Other values still need a restart, and the mod states which ones.
The mod runs on the server only, so players join without installing anything. Commands require operator level 4. Files are published for Fabric, for 1.21.10 – 26.3, under the GNU General Public License v3.0 or later, and the code is open source.
Key features
Live server.properties reload
Changes to server.properties take effect on the running server, so no restart is needed for supported values.
Immediate MOTD and distance changes
View distance, simulation distance, the MOTD and the idle timeout can be adjusted while the server keeps running.
Persistent edits
Changes are written back to the properties file, so they remain in place after the server restarts.
Compatibility
Latest build for each game version and loader.

How it compares
Custom Server MOTD is server-side only and released under the MIT License, with files for 1.20.3 – 1.21.11, so it covers only MOTD changes. Server Restart Command is also server-side and MIT-licensed, but targets 26.1 – 26.2 and handles restarts rather than live property edits.
