Ornithe Standard Libraries
Ornithe Standard Libraries is a set of library modules for Ornithe, providing shared APIs that other mods build on.
What it does
Ornithe Standard Libraries groups several modules under one name. The Core API supplies common utilities such as an events system and registries that the other modules use. Blocks, Items, Config, Entrypoints, Lifecycle Events, Localization, Networking and Resource Loader APIs each cover one area, so a mod can depend on only the pieces it needs. Each module can be added as a separate dependency.
The Ornithe loader is the only loader listed, and the libraries cover game versions a1.0.4 – 1.14.4, with 120 release versions in total. The Modrinth page lists snapshot builds as published, and the latest Ornithe file is 0.22.2 for 1.14.4, dated 2026-10-12, on the beta channel. The license is the Apache License 2.0, and the source code is open source. Clients and servers both run the library, so it has to be present on each side.
