Chainner sucks the UI is awful not user friendly at all and upscaling images with this program is slower than a brick wall. It should not take 20min+ to upscale one image even if your upscaling a images to 4x 8x or 16 with any model it should not take 20min+ . Upscayl is way better way easier to use and much faster.

Although it is currently in alpha version, it is a very well developed software. "Node-based" image editor

Overall the best application for upscaling images in 2024. Out of all alternatives, chaiNNer is the most consistently updated and supports the greatest feature set.
One of the best Open Source applications and its still in Alpha, the crazy amount of things you can in this is absurd. You can upscale single images, use the image file iterator to do an entire directory and the video file iterator does entire video's etc. OpenModelDB has so many different pretrained models. You can do stable diffusion as well for generating art, but I haven't used it for that yet.
Why is this application so underrated?
