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.

• Complete Component but hard to use - file export are 1 by 1 (cant bulk)
Okay. It's nowhere near being an alternative to Microsoft Visio, but it was my initial go to when I started off consulting and wanted to quickly produce flowcharts and mock ups.
The interface was not that enticing but it's served it's purpose as a stepping stone.
Unfortunately, the Windows side has suffered for a long time. So, I have been happily using draw.io/diagramming.net. But, if you want open source then look at LibreOffice - Draw.
Light, free, simple and many features. Grid snapping can be upgraded thought.
Like that software. It's a bit unhandy sometimes but in the end maybe the best libre software there is for that purpose.
Dia has somewhat stagnated in recent years. For a long time it was the only real open source option other than turning to Inkscape and doing everything from scratch. These days I'd recommend you try Pencil instead because it has a much nicer UI and arguably better features.
I successfully made some diagrams with Dia but, as another user said, its interface is really clunky. Now I'm trying yED.
Dia on Linux - shines.
I was able to use it to create all sorts of logic diagrams - for programming and for organization. It is also capable to unite any elements and group and supports layering. Perfect software!
