In their own words
Fallout 4 Script Extender (F4SE)
Fallout 4 Script Extender (F4SE) is a free Windows resource for Fallout 4 modders who need expanded scripting capabilities. It extends scripting without changing the game’s executable files on disk. Listed interfaces include the Papyrus plugin API and hooks for Papyrus, Scaleform, and the classic script system. The homepage lists build 0.7.9 for Fallout 4 runtime 1.11.240. F4SE supports Fallout 4 releases from Steam and GOG, while MS Store, Game Pass, Epic, and other Windows Store versions are unsupported because those applications do not provide required APIs. Native code plugins require updates from their creators for runtime 1.10.980 and later, and plugins must have publicly available source code. Injection loads mods and may trigger poorly written virus scanners. Additional utilities include a command-line BA2 archive extractor and PEX script disassembler. The project is provided as-is and directs installation questions to its subreddit.
Hollow Knight Modding API
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.
