Everest vs Hollow Knight Modding API

Everest is a free, open-source mod loader and modding API for Celeste. It lets players use mods with custom maps, texture replacements and code-driven additions such as sound effects, graphics, dialogue and campaigns, without changing original game files. An in-game updater and dependency downloader help manage mods. The cross-platform Olympus installer can install mods with one click from its Download Mods section or GameBanana, or from ZIP files and folders; players can also switch between Everest and vanilla Celeste through Olympus or the title screen. Everest supports Windows, macOS and Linux and works with Celeste from itch.io, Steam and Epic Games, but not the Windows Store version. Enhanced Debug Mode offers live map reloading, code and asset reload shortcuts, an improved map viewer and console logging. The project is MIT-licensed and maintained by volunteers. Olympus is actively being worked on and may fail, and the project directs users to the Celeste Discord’s #modding_help channel for bug reports and questions.

Hollow Knight Modding API is a free, open-source API and loader for Hollow Knight modifications. Its primary purpose is helping mods work together; it does little independently, but several mods require it to run. Loading uses injection, and the project provides load-order control. The implementation uses MonoMod. The repository includes examples for mod developers and links to API documentation on a DocFX site. Users can obtain a release or installer, 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. The supported game is Hollow Knight, and supported operating systems are Windows, Linux, and macOS. The project is distributed under the MIT license, which supplies the software as-is and disclaims warranties and liability. Steam and GOG users are instructed to verify or repair the game installation when removing it. There are no paid tiers or usage limits stated.
