About this Mod
Builtin Servers
A small mod that lets modpack makers set up built-in servers instead of shipping a preconfigured server.dat file.
Setting up the mod for your modpack:
If you want to add default servers that will show up in the server list when players download your modpack, just run the mod once and edit the config file generated at .minecraft/config/builtinservers.json.
After that, ship your config file with your modpack, and all new instances will have your servers, but old instances will not lose their custom servers when your modpack updates.
Here is what the default config file should look like:
Builtin servers will show a custom badge on the client so that players can see which servers have been added by the modpack (this can be disabled):
Forced servers cannot be deleted and will always be re-added unless the config file changes. They cannot be edited/removed and will show a custom message:

Does Builtin Servers need to be installed on the Minecraft server?
No. Modrinth marks Builtin Servers as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does Builtin Servers require?
Use a file for fabric, forge and your exact Minecraft version. Supported versions include 1.20.1, 1.19.2, 1.19. Files for different loaders are not interchangeable.
Builtin Servers is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
