This list contains slop-free (without LLM generated code; supposedly) open source software. It is a positive counterpart of Open-Source Slopware. Check out and give thumbs up also to AI Slopfree Software Catalog which contains software dedicated against LLMs!
Applications in this list are deemed slop-free by a quick eye test, so it does not necessarily mean that they indeed are not tainted with machine generated code.
So, why is it important to avoid LLM generated code?
- Ethical reasons — such as illegally retrieved training material, underpaid workers that prepare 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 neighborhoods near AI data centers, air pollution from diesel- or gas-powered turbines (also overlaps with the above), drastically increasing 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). 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.
I will try to add links at some time to the statements above to back them up.
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 outweighs gains.

From Contributing — AI-Generated Code:
Please do not submit AI-generated code. My views might be somewhat old-fashioned in this regard, but I think coding is for fun and so is the whole of this project. Therefore, I expect contributions to be "hand-written". Letting some LLM run over the code base and then blindly submitting its output is not the point of open source in my opinion. I'd rather want contributors to spend time familiarizing themselves with the code base, try to wrap their heads around how things work under the hood and then start coding.
Nevertheless in contributors page it can be seen that one commit by claude has somehow managed to slip through.
