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.

Comments and Reviews
This ultra-minimalist server reminds me of an old Web 1.0 guestbook (minus the garish backgrounds and colors). And yet it not only lets you post text and images and follow people on other servers...it interacts just fine with Mastodon, PixelFed, GoToSocial etc. while using hardly any RAM or processing power. Very low admin tax, especially compared to Mastodon. A great choice for a small group or single-person Fediverse presence.
Best lite ActivityPub solution for personal use or small community!
