AI Slopfree Software Catalog

A more optimistic homage to the slopware catalog https://alternativeto.net/lists/44427/slopware/, this list is designed to showcase projects, both FOSS and proprietary, which reject contributions from Generative AI LLM slop machines. The most pessimistic thing about this list is how short it is and how so many commonly used software solutions and websites are not included. I have to give it up to the following sites for providing references: https://codeberg.org/brib/slopfree-software-index https://github.com/melissawm/open-source-ai-contribution-policies There are a lot more projects on this list which I didn't include because they aren't on AlternativeTo (yet). I'll be adding more entries to this site (and removing those who fold to the AI overlords) on a regular basis. I'm including references, which are all first-hand declarations from the development teams for each entry to ensure items aren't included based on hearsay or conjecture. Updated 10-2-2026

What is Decker?

»Decker is a multimedia platform for creating and sharing interactive documents, with sound, images, hypertext, and scripted behavior.

Decker builds on the legacy of HyperCard and the visual aesthetic of classic MacOS. It retains the simplicity and ease of learning that HyperCard provided, while adding many subtle and overt quality-of-life improvements, like deep undo history, support for scroll wheels and touchscreens, more modern keyboard navigation, and bulk editing operations.«
