About U-API
U-API is a lightweight foundational library for Minecraft mods built around the U-API ecosystem.
It provides shared systems, utilities, and integration points used by dependent mods, helping them stay consistent, modular, and easier to maintain.
U-API is not meant to be a standalone content mod.
You should install it when another mod lists it as a required dependency.
What it is used for
- Shared API foundation for related mods
- Common utilities and internal systems
- Consistent integration between dependent mods
- Cleaner modular structure for future projects
For players
Install U-API only if a mod requires it.
By itself, U-API does not add new gameplay content, blocks, items, mobs, dungeons, or progression systems.
For modpacks
U-API can be safely included in modpacks when required by other mods from the same ecosystem.

3.0.0-beta.2+mc26.2Бета26.2 · 22 июля 2026 г.
- Deferred HUD element dimension sampling until the render/layout phase so client lifecycle registrations cannot access an uninitialized Minecraft window.
Compatibility
- Minecraft: 26.2
- Loader: NeoForge
- Java: 25
3.0.0-beta.1+mc26.2Бета26.2 · 22 июля 2026 г.
- Ported U-API to Minecraft 26.2, NeoForge 26.2.0.28-beta and Java 25.
- Migrated identifiers, retained GUI extraction, input events, permissions and server reload events to their 26.2 APIs.
- Migrated instance persistence to codec-backed
SavedDataTypestorage. - Updated JEI compile-time integration to the Minecraft 26.2 line.
- Added pull-request CI and updated tagged GitHub/Modrinth releases for prerelease versions.
- This is a clean-install beta line; 1.21.1 worlds and configuration are not migrated.
Compatibility
- Minecraft: 26.2
- Loader: NeoForge
- Java: 25
2.0.0+mc1.21.1Релиз1.21.1 · 19 июля 2026 г.
- Added lifecycle-scoped public service discovery without dependencies on consuming mods.
- Added neutral social-group, ready-check, permission and bounded public-profile-facet contracts.
- Added protocol negotiation, request correlation, bounded rate limiting and connection request tracking.
- Added a retained client UI runtime with layouts, themes, focus, reusable controls, virtualization, modal/toast primitives and deterministic cleanup.
- Unified first-party screens on the Soul-inspired
ARCANEtheme and fixed render ordering so vanilla blur cannot be applied over completed retained UI. - Added collision-aware HUD registration and bounded, interpolated, privacy-neutral world overlays.
- Added bounded player-head caching and client connection cleanup.
- Expanded opt-in diagnostics for services, UI, HUD, overlays, caches and packet rates.
- Added common/server configuration for optional integrations, debug logging and network bounds.
- Made 2.0 a breaking clean-install line: removed the migration API, required exact current versions for instance storage/sidebar JSON and dropped source-compatibility promises for 1.x.
Compatibility
- Minecraft: 1.21.1
- Loader: NeoForge
- Java: 21
1.3.1+mc1.21.1Релиз1.21.1 · 10 июля 2026 г.
- Added JSON-driven container helper buttons in the fixed top-left screen corner.
- Added built-in helper actions for gamemode survival/creative, weather clear/rain, morning and night.
- Limited helper rendering to container screens so custom non-container UIs do not get overlapped.
- Added optional JEI compatibility: helper buttons are offset below JEI's top-left bookmark controls and registered as a JEI extra GUI area.
- Added per-button
permission_levelchecks for server-safe helper commands. - Narrowed declared Minecraft/NeoForge support to the tested 1.21.1 / 21.1.x line.
Compatibility
- Minecraft: 1.21.1
- Loader: NeoForge
- Java: 21
1.2.0Альфа1.21.1 · 5 июля 2026 г.

- Standardized manually edited Common, Client and Server configuration files under
config/uapi/u-api/. - Removed the experimental in-game configuration editor, its screen registry and raw text editor before release.
1.1.0Альфа1.21.1 · 4 июля 2026 г.
