LAN Properties
Enhance the vanilla "Open to LAN" interface to provide full control over all server settings, just like in server.properties on a dedicated server.
About this Mod
What is LAN Properties?
How do I use it?
Simply install the mod and click "Open to LAN" as normal. There will be a configuration button that lets you customize all server settings.
Hybrid Mode
LAN Properties introduces an additional property called hybrid-mode.
When online-mode is disabled but hybrid-mode is enabled, the server attempts to authenticate players in a "best of both worlds" approach:
- If an account with the player’s username exists → The server fetches the official UUID from Mojang’s session servers.
- If the session servers are unreachable or the username does not belong to a valid account → The server falls back to using an offline UUID.
This ensures that premium (online) players always keep their correct UUID, while still allowing offline players to join when needed.

LAN Properties server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.8). You can switch loaders with one click in the panel.

LAN Properties officially supports fabric, forge, legacy-fabric, neoforge, ornithe, quilt for Minecraft 1.21.8, 1.21.7, 1.21.6. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with LAN Properties – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if LAN Properties consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
