A list of open-source software containing slop (LLM generated) code or endorses the usage of LLMs in other ways. This list contains software that obviously accepts irresponsible coding practices or promotes LLM usage. I found these applications while searching for alternatives to previously used software that turned out to contain code generated by slop-machines. Each of added applications have at least one link that points to the verifiable proof. This list by no means is meant to cover all the software that contains code by not-so-intelligent tools and people using them but to serve as a reminder to myself about what I have already checked. Why having LLM generated code (and using generative tools in general) is bad? Ethical reasons — such as illegally retrieved training material, underpaid workers that prepare the training data. Impact on environment — increased fossil fuel usage to supply the needed electricity power, water usage in water scarce regions. This somewhat overlaps with the above. Social impact – noise pollution in neighbourhoods near AI data centres, air pollution from diesel- or gas-powered turbines (also overlaps with the above), resource consumption by data centres drastically increases utility prices. Impact on brain and thinking, reasoning — by offloading thinking and decision making to machines people are shooting in their foot (more like in their head) as this leads to brain rot. Less intelligent people are easier to control. Even legal issues (especially in open-source software as it cannot be guaranteed that the “generated” code is not really just re-used, thus unknowingly violating the source license). Inevitable enshittification — every software product from big technology eventually gets enshittified to maximize revenue. For users this could mean hidden or plain ads, biased opinions/information, privacy violations, increased prices for LLM based tools. Burden on open-source software maintenance — LLM tools provide easier access to code contributions which often shifts the responsibility of checking code quality from developers to maintainers and reviewers. Digging through walls of merge request text and code generated by slop-machines takes valuable time that otherwise could be spent more meaningfully by fixing bugs and working on new features. I will try to add links that back up the claims above, but it may take a while. Of course, I see how and where generative tools could be helpful and sometimes I feel tempted to find an acceptable way to use them, but for now the direct and indirect costs far too much outweigh gains. This list has its positive counterpart: Slop-Free (Supposedly) Open-Source Software (not quite complete yet). Also take a look at and give thumbs up to AI Slopfree Software Catalog which contains software dedicated against usage of LLMs. Also, here is a list of some labels that can be added / voted for so they would eventually appear on application pages: Slopware; Slop (LLM) Code; Slop-Source Software; Open-Source Slopware; Contains Slop (LLM Generated) Code.

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 9-27-2026

Just a curated list of stuff I use often.
