Compatibility
Minecraft Version
UltiTools 6.2.x supports Minecraft 1.21 and above.
Older versions not supported
UltiTools 6 does not support 1.20.x or below. Please upgrade to Paper 1.21+.
Server Software
Paper (Recommended)
UltiTools is developed and tested for Paper 1.21+. Paper is the recommended server software.
Paper Forks (Purpur, Folia, etc.)
Paper-based forks should work in theory but are not officially tested.
Spigot
UltiTools uses some Paper-specific APIs (such as Adventure components). Running on vanilla Spigot may cause compatibility issues. Migrating to Paper is recommended.
Unsupported
- CraftBukkit
- Sponge/SpongeForge
- BDS (Bedrock Dedicated Server)
Modded Servers (Mohist/Arclight, etc.)
Not officially supported. May work, but issues won't be investigated.
Optional Dependencies
| Plugin | Required? | Purpose |
|---|---|---|
| Vault | Optional | Economy API, required by UltiEconomy, UltiKits, etc. |
| PlaceholderAPI | Optional | Placeholder variables, required by UltiSideBar, etc. |
| LuckPerms | Optional | Permission management, recommended |
Compatibility with Other Plugins
Economy Plugins
UltiTools integrates with the economy system through the Vault API. Any economy plugin that supports Vault will work. If you install UltiEconomy, it automatically registers as a Vault economy provider.
Login Plugins (AuthMe, etc.)
If you use another login plugin, do not enable the UltiLogin module to avoid command conflicts.
LuckPerms
UltiTools has official LuckPerms support. See Permissions.
BungeeCord/Velocity Proxy Networks
UltiTools does not have a BungeeCord/Velocity plugin. Install UltiTools on each sub-server and configure a shared MySQL database for data synchronization.
See Database & Sync.
Geyser Compatibility
Geyser has not been officially tested. Users have reported that inventory-based GUIs may have display issues on Bedrock clients.
