Default Server Properties

What the mod doesDefault Server Properties is a server-side utility designed for modpack creators. It allows pack developers to define baseline server configurations before a dedicated server launches for the first time. You place a custom file named default-server.properties in the root directory of your pack. The mod uses mixins to intercept the standard setup phase. When the server builds its initial configuration, the mod injects your custom entries directly into the normal server.properties creation routine. You don't need to list every single game option. Pack authors only include the specific keys they want to change, such as setting a default level type for a custom world. The game's native loader takes care of all other normal properties automatically.## How file injection worksThe loading check relies on a tracking file. The mod searches the root folder for default-server.properties. It also inspects the local folder for a file named default-used.marker. If default-used.marker is missing from the local folder, the mod attempts to load the provided defaults and injects that data into the default server.properties creation. Once this runs, server administrators can adjust their server.properties freely without having their changes overwritten on future restarts.## Side support and compatibilitySide requirements are strict. The mod is required on the server side. It's unsupported on the client side, so you don't install it in client environments. For loaders, the project supports Fabric and Neoforge. The mod supports Minecraft versions 26.3, 26.2, 26.1.2, 26.1.1, 26.1, and 1.20.6.## Project details and licensingThis tool is built for modpack creators who distribute server packages and need consistent starting properties. Instead of manually editing server.properties files or bundling full pre-made config files that might miss new engine defaults, pack authors can provide only their intended overrides. The project is developed by ErrorMikey and published under the Mozilla Public License 2.0. It belongs to the Utility & Quality of Life category on Modrinth.
