Krnl is a free-to-download and use Roblox script executor for Windows 10 & 11 PCs (64-bit only). It is one of the few famous ones that are still updated to this day. It supports advanced features like a debug library, and drawing library, and can also run super complex scripts such as Owl Hub.
Although it is free, it does work on the traditional linkvertise key system that has to be repeated every 24 hours. It is not available on Android mobiles as of September 2023 but you can use Arceus X as an alternative.
