About this Mod

Unified API

Unified API is a cross-loader API for both Fabric & NeoForge that enables you to create multiloader mods at no additional effort.

This is accomplished through Unified API's custom registries, events and helpers which replace the need for platform-specific code in favour of using Unified API's common-friendly, well-documented alternatives.

Unified API has no dependencies - simply Fabric API for Fabric, or base NeoForge for NeoForge.

For comprehensive documentation alongside a setup guide, check out unified-api.dev

Why use the Unified API over another API?

  • Deferred Registries allow you to register content for any vanilla or modded registry
  • a ton of easy-to-use, documented events - including some extremely powerful ones such as the Loot Table, Default Data Component or Biome Modification events
  • helper methods to handle any common loader-specific code, often in ways that further expand functionality (such as BLOCK_CONVERSIONS, STRUCTURE_MUSIC or CREATIVE_ENTRIES)
  • data-component-driven functionality such as furnace fuel or compost components
  • no breaking changes to the API in the same Minecraft version, and changes made between full MC releases of the API are thoroughly documented in the migration guide
  • consistent ports to the latest versions, with features designed with them in mind

Registries include:

  • Deferred Registry
  • Items
  • Blocks
  • Entity Types
  • Block Entity Types
  • Creative Tabs
  • Data Component Types
  • Sound Events
  • Key Mappings

Helpers include:

  • Platform (check for mods / modloader / other instance information)
  • Packs (register internal data / resource packs)
  • Creative Entries (insert items to creative tabs)
  • Networking (register, send & handle packets)
  • Biome Modifications (akin to the fabric biome api, easily modify the features, carvers, effects, attributes or climate of any biome)
  • Block Conversions (custom block swapping behaviour such as strippable logs)
  • Particle Providers (create custom particles for the client)
  • Entity Renderers (setup rendering for custom entity / block entity models & textures)
  • Tooltips (bind custom client tooltip information to a tooltip, similarly to bundles)
  • Data Components (append custom components to blocks / items such as furnace fuel or compost behaviour, or any other component)
  • Structure Music (register unique music pools to any structure)
  • Legacy Baby Armor (automatically resize, and optionally rescale, adult armor to match baby mobs without requiring dedicated textures)

Events include:

  • Default Data Components (filter for & modify the default components on any item)
  • Loot Tables (append any loot table with new pools, or directly edit existing loot entries)
  • Commands (create custom commands)
  • Players (run code on player events such as join/leave/respawn)
  • Ticks (run code at the start / end of client ticks, such as custom keybind code)
  • Guis (append hud rendering such as crosshair and hotbar rendering)
  • Screens (access AbstractContainerScreen in order to create custom mouse behaviour)
  • Servers (run code on server start / stop / datapack load / server ticks / level ticks)

Components include:

  • Furnace Fuel (easily specify custom furnace fuel durations for any item)
  • Compost (make any item compostable with a given float chance)

Tags include:

  • Persistent Cooldowns (enforce item cooldowns on tagged items per-player between world loads)

Once again, be sure to check out unified-api.dev for documentation and the full feature set.

Frequently Asked Questions

Unified API 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 (26.1.2). You can switch loaders with one click in the panel.

Is Unified API compatible with fabric and neoforge?

Unified API officially supports fabric, neoforge for Minecraft 26.1.2, 26.1.1, 26.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Unified API – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Unified API 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.
