    QBooru

    QBooru

    Simple viewer app for most Booru Sites, coded in Qt C++

    QBooru is a lightweight Windows and Linux client that allows users to see pictures from most booru sites, and download them, for example : - Gelbooru - Danbooru - Konachan - Yandere - Safebooru - Rule34 At the moment, it supports 4 APIs : - Gelbooru - Danbooru 2 - Moebooru - Derpibooru Searchs are done by the JSON APIs. Thumbnails are cached locally, and are re-used by the program if needed. Interface The current interface allows users to chose how many pictures they want, within 3-5 rows and 5-8 columns. The recommended size is 3*5, as it fits perfectly the smallest window size. Search tab example : http://puu.sh/cK0pj.jpg Users can change nearly all the parameters through the Option tab, or by editing the configuration.json file. Boorus can be added, edited, and deleted through the Booru tab in the software, but they can also be edited manually in the configuration file.
