Here is our small collection of software tools you can use to make your own local copy of your favorite artists' works.
Fantia.jp archival tool for .NET/Mono. Supports downloading images, videos and other attachments.
Furaffinity.net gallery downloader for Windows. Purpose-built for Furaffinity, thus supporting some highly specific features like content update detection which multipurpose tools sometimes struggle with.
A tool to automatically download galleries and images from the specified HicceArs artists. Runs everywhere Node.js can run, with self-contained executables available for Windows.
The best tool to download content from Pixiv and Fanbox.
SimilarImages allows you to quickly find duplicate images stored locally. Useful for searching for fullsize versions within a large dataset using the reference thumbnail; together with AntiDupl.NET it is the only one capable of doing this task on a dataset of 200 000 files in a reasonable time.
Unlike the tools above, these publish the scraped content for every site visitor to see.
Supports Patreon, Fanbox, Gumroad and Fantia.
Some lesser-known forks of the Kemono's engine also exist.
Supported Patreon and, somewhat unreliably, Fantia.
