Raffmans Auto Modder

Join a modded server – Auto Modder installs the mods it needs for you.

Install one mod, join the server, say yes. Auto Modder shows which mods are missing, downloads them, installs them and restarts Minecraft. Made for players who have never used mods before.

For players

1. In the CurseForge app, create a profile with Minecraft 1.21.1 and NeoForge 21.1.264, then add Raffmans Auto Modder.
2. Join the server.
3. Click Download mods → I trust this server → Install & restart. Minecraft restarts by itself (if not, just click Play). Done!

When the server adds or updates mods, you get them automatically the next time you join.

For server owners

Put the mod into your server's mods folder and start the server. No config, no extra port.

Features

• Only what you need – client mods are detected automatically, server-only mods are left out.
• Automatic updates – new mod versions replace the old ones.
• Fair to mod authors – mods on Modrinth are downloaded from Modrinth, so their authors get the download. Mods whose license doesn't allow sharing are never sent by the server: players get a link, and Auto Modder picks the file up from their Downloads folder.
• Safe – a preview of every change, checksums, backups and an automatic undo. Mods the server doesn't use are never touched.
• English and German

Safety

Mods are programs that run on your computer – only join servers you trust. Downloads from the server are not encrypted.

Server owners: Auto Modder follows the licenses that mod authors declare. Mods it holds back are listed in the server log; add them to share.allowed in config/raffmansautomodder-server.properties only if their authors agreed.
