- [Dandere2x ](https://github.com/CardinalPanda/dandere2x ): A lossy video upscaler also built around `waifu2x` , but with video compression techniques to shorten the time needed to process a video.
- [Waifu2x-Extension-GUI ](https://github.com/AaronFeng753/Waifu2x-Extension-GUI ): A similar project that focuses more and only on building a better graphical user interface. It is built using C++ and Qt5, and currently only supports the Windows platform.
