Hollow Knight Modding API
What it is
Hollow Knight Modding API is a free, open-source API and loader for Hollow Knight modifications. Its main purpose is helping mods work together; several mods require it, while the API itself does little independently. Mod loading uses injection and includes load-order control. The project uses MonoMod, provides examples for mod developers, and links to API documentation on a DocFX site. Users can obtain a release or installer from the repository, then copy release ZIP contents into the Hollow Knight game folder or install through Scarab. The latest listed release is ModdingAPI v77 for Hollow Knight 1.5.78.11833, with checksums for Windows, macOS, and Linux. Hollow Knight is the supported game, and the project lists Windows, Linux, and macOS. It is distributed under the MIT license, which provides the software as-is and disclaims warranties and liability. Steam and GOG users are instructed to verify or repair their game installation to remove the API.
