Hollow Knight Modding API vs ModTek

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.

ModTek is a free mod loader for HBS’s BattleTech PC game. It loads mods at game startup when they use the mod.json format, allowing modders to package self-contained changes without overwriting game files. It resolves dependencies and controls load order without requiring edits to VersionManifest.csv. The project says newer versions include DLC support not present in BattleTech’s built-in 1.7 loader. It supports BattleTech installations from Steam and GOG on Windows, Linux, and macOS. Installation uses a downloadable ZIP extracted into the game’s installation folder; the instructions warn that the game should be outside Program Files because Windows UAC protection can interfere. Version 3 and later use UnityDoorstop to load ModTek without modifying game files. The repository documents JSON and DLL mods, advanced JSON merging, manifest manipulation, and HarmonyX support. The project is licensed under LGPL-2.1. Linux instructions describe a system-wide ASLR change as an obsolete, insecure workaround and provide an environment-variable fix instead.
