Friday Night Funkin' is licensed under the Apache License 2.0, per the game's license file, and it is described as "fully open source" by its developers in the readme file included with the game. However, the repository's readme file states, "IF YOU MAKE A MOD AND DISTRIBUTE A MODIFIED / RECOMPILED VERSION, YOU MUST OPEN SOURCE YOUR MOD AS WELL", implying a copyleft requirement. From May to August 2021, the license file simply stated "if u make mods, open source them, lol!"; the Apache License 2.0 was used prior to May. In a tweet, ninjamuffin99 stated that it gets "iffy" when non-code assets are used commercially. Since January 2023, the license file simply reads "SORTING OUT LICENSE STUFF!!! BRB LOL!".
