A web app built with Streamlit in Python to create Arknights mobile wallpapers on the fly. The art was scraped from Gamepress and images are loaded directly from their source. This scraping is done with with the requests and BeautifulSoup4 libraries. The default colors for each operator was done manually by me.
Simply choose your favorite operator and the wallpaper will be generated in the moment. You can filter operators by rank (number of stars), and choose a theme color if you don't like the default one and even play around with skins!
