Every feature can be individually enabled or disabled. Don't need announcements? Turn them off. Don't want the warn system? One toggle. Your config, your rules.
| Mod | What SEF does with it |
|---|---|
| LuckPerms | Pulls prefixes, suffixes, group info into chat & tab list |
| FTB Essentials | Nickname support, mute integration, replaces /invsee with enhanced version |
| Curios | Full Curios slot support in /invsee and banned item scanning |
| Simple Discord Link (SDLink) | Hides private/admin chat from Discord, fake join/leave for vanish |
All integrations are optional — SEF detects what's installed and adapts automatically. Works perfectly standalone.
Unlike most "server" mods, SEF works in singleplayer worlds and Open-to-LAN sessions too. Use the chat formatting, color codes, and QoL features even when playing alone or with friends.
mods/ folder (Forge 1.20.1)/sef reload to apply changes without restartNo dependencies required. LuckPerms, FTB Essentials, and Curios are optional enhancements.
50+ granular permission nodes (sef.*) — fully compatible with LuckPerms. Every command and feature has its own permission node so you can fine-tune access for every rank on your server.
