About this Mod
AutoInstaller
Automatically prompt players to install server-required mods when joining.
How It Works
When a player connects to a server running AutoInstaller, they'll see a mod selection screen showing all mods the server requires or recommends. Players can:
- Install Mods - Download and install selected mods directly
- Play - Join the server without installing (if no required mods are missing)
- Cancel - Return to the server list
Features - Required & Recommended Mods - Server admins can mark mods as required (must install) or recommended (optional)
- Smart Detection - Automatically detects which mods the player already has installed
- Dependency Resolution - Automatically fetches mod dependencies from Modrinth
- No Restart Needed to Join - Click Play to join immediately after viewing the mod list
- Clean UI - Simple, intuitive mod selection screen

AutoInstaller 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 (1.21.10). You can switch loaders with one click in the panel.
Is AutoInstaller compatible with fabric?
AutoInstaller officially supports fabric for Minecraft 1.21.10. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with AutoInstaller – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if AutoInstaller 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.
