I love what F-Droid stands for and I like the freedom that it gives its users. As a FOSS app maintainer I also have nothing but good things to say about the people behind the project. Maybe they’re even a bit too nice, considering how many times repro has failed due to me forgetting to commit before building 😅.But my god is it hard to find human-written software now.Intro#The problem#Sometimes I open F-Droid just to browse. You know, maybe I’ll find an app that solves a problem I didn’t know I had, or maybe I’ll find a better alternative to something I already use.And one day, while browsing, I noticed an app with an obvious and ugly AI generated icon. It’s not on the list and I will not shame it, but it got me thinking. How much of F-Droid is AI?As someone who does programming for fun and is only a student, untarnished by honest work, I get my knowledge of what the coding world is like mostly from clickbaity YT videos and Reddit posts of CS professionals. They either describe LLMs as god reincarnate or as glorified autocomplete.Both are, obviously, wrong, but that’s not really helpful in determining what I want to know. What is the actual state of programming nowadays? Whenever I use FOSS software, how likely it is that it has been vibe-coded by a rando in an afternoon?How to know if an app is vibe-coded?#That’s the trick—you can’t. Text just doesn’t carry enough meta information for any kind of assessments to be even close to accurate. However, just as that em-dash I used in the first sentence probably triggered an alarm in your brain, there are signs.While that does make the task at hand sound fickle and dependent on happenstance, the signs, especially concerning LLM code repositories, are never too hard to find.You see, the main allure of LLMs is that they allow the developer to be more lazy. That’s kind of the whole point! You just prompt, sit back and relax. So it should not surprise you to hear that this attitude is then reflected in everything the vibe-coder touches.Why write a README from scratch? Lol, just let the LLM do it.Do code-review? Naw, just let the LLM review its own changes and then also give it access to the repo so you don’t even need to press the commit button.If a project was concerned with looking legitimate, it would be trivial to do such things by hand. But it’s low effort all the way down.My biases#This part can be skipped if you don’t care about my stance on LLMs, but I need to make my position clear to avoid contributing to the circlejerk too much.To begin with, I’d like to acknowledge that LLMs are incredibly useful and capable. As 2026 has progressed, this has become more and more visible, but people being able to one-shot medium scale games and software in half an hour is ridiculously impressive, even if the end product is usually not very good.I also am very much in favor of software getting faster and more secure. The story of the Linux kernel development has shown that LLMs are capable of finding and sometimes even solving many types of code issues.With the pleasantries out of the way though, I have to admit I really hate LLMs and what they have done to programming, related engineering fields, and society as a whole.Their mere existence makes educating yourself and going on fun side projects much less rewarding. Like yeah, I did something, but with an LLM I could have done this in a quarter of the time. And when you do take the black pill and vibe-code, it’s even worse. It’s not like you did anything. The machine did that.Then there’s the atrophying effects on human brains, their unfathomable capability for serving plausibly sounding misinformation and the climate disaster that we’re just kinda ignoring. All very fun things to think about.Criteria / The experiment#As mentioned before, there’s no way to effectively detect slop, so I propose a rough 3 tier system based on the aesthetics of the repo:Mostly AIThis is mostly for projects that have significant LLM smells and means I expect >50% of the code is LLM authored. Any kind of agentic infrastructure automatically lands an app in this tier as I do not believe it is possible to use AI responsibly from within a coding harness.Hard to say / Mostly human / OtherOccasional LLM commits either by maintainers or contributors, but mostly looks human. May have an LLM policy which permits certain uses. This tag means I expect <50% of the code is LLM authored.No signs of AICould not find anything suspicious/Has a strict LLM policy.Note that my rating will still be quite superficial and the tiers quite loose. I did not build a “slop detector” or anything like that, so my decisions are based on looking at recent commits and their content along with the project’s branding.Also note that since I have no way of knowing for sure, there may be errors. I still believe most of my findings to be accurate however.I will also not look at the history of the app. If it has existed since 2014 but recent commits are LLM authored it will be categorized as “mostly AI”The apps chosen were the batch of updates pushed to F-Droid on September 12, 2026. That amounted to 102 apps, which was quite a lot of work for me to go through.😅If you just want the results, feel free to skip to the resultsApps#Amber#Description: Nostr event signer for AndroidRepository: https://github.com/greenart7c3/AmberRating: Mostly AIJustification: All recent commits were done with LLM, PRs accepted from agents, Claude Code and Codex infrastructure present.Aria for Misskey#Description: Dive into the interplanetary microblogging platform 🚀Repository: https://github.com/poppingmoon/ariaRating: No signs of AIJustification: This is a hard one as commit naming and structure felt a bit suspicious, but I did not see anything else and decided to err on the side of cautionAtmo Engine#Description: Animated wallpapers with Atmosphere, Glass, Canvas Sketch and playlists.Repository: https://github.com/saad-khan-rind/nosatmosphereeffectRating: No signs of AIJustification: Heavy emoji usage in the README, but otherwise nothing looks suspicious.Aves Libre#Description: Gallery and metadata explorerRepository: https://github.com/deckerst/avesRating: No signs of AIJustification: Nothing looked suspiciousBalance#Description: Private offline bank balance dashboardRepository: https://github.com/AshkanRafiee/balanceRating: Mostly AIJustification: Code and commits exhibit various AI smells.Baly Groceries Tracker#Description: Track your groceries, without worrying about running out.Repository: https://github.com/rw-account/baly_groceries_trackerRating: Mostly AIJustification: Code and commits exhibit various AI smells.Bati: Fitness RPG#Description: Turn workouts into quests, boss fights and a village built by your training.Repository: https://github.com/Guiforge/batiRating: Mostly AIJustification: AI disclosure in README (Thanks for making it easy :D)BayesianBahn#Description: Empirical arrival-time distributions for Deutsche Bahn trainsRepository: https://github.com/DerWeh/BayesianBahnRating: Mostly AIJustification: All commits are Claude co-authored.

10 were hard to categorize one way or another (9.8%)
18 showed little to no signs of AI involvement (17.6%)
Really not sure how to cope with these numbers though.On one hand, some seem to have quite a few users. And if people are having their lives improved by using said software, who am I to say “no”?On the other hand, I’m really concerned about what the data means for the FOSS community as a whole.I explicitly did not do any code quality analysis as that would have taken much more time and would have probably been out of my skill level anyway, but I am curious about the robustness and maintainability of the 72%.Just for fun I also checked a few of the FOSS apps I actually use and quite a few showed signs of heavy LLM usage.I’ll still use them, as I find them useful, but this whole experiment has left me feeling quite conflicted.I know how to fix this though:Hey Claude, make a load-bearing time machine set to 2016 – a time when I was a happy kid, nothing bad ever happened and all was good in FOSS-land.Make no mistakesOpen Source© 2026 tintotint's site ·

PaperMod

The provided text details an investigation into the extent to which applications on the F-Droid platform are generated using Large Language Models (LLMs), framed around the question of whether software development is being "vibe-coded." The author, acting as a FOSS application maintainer, explores the philosophical and practical implications of LLM use in open-source software creation, acknowledging both the utility and the broader societal concerns.

The investigation begins by establishing the difficulty in accurately detecting AI-generated code, noting that text alone lacks sufficient metadata for reliable assessment. However, the author posits that visual and repository-level cues, particularly in LLM-related code repositories, provide observable signs of AI involvement. This observation stems from the general appeal of LLMs—the ability to reduce the cognitive load on developers, allowing them to automate tasks like writing READMEs, code reviews, and generating code, which the author views with deep ambivalence, ultimately feeling that LLMs diminish the rewarding aspects of personal development.

To address the ambiguity, the author proposes a heuristic, three-tier classification system based on the aesthetics of repository commits and branding rather than attempting to build a rigorous automated detection system. The tiers are Mostly AI, Hard to say/Mostly human/Other, and No signs of AI. The categorization is informed by examining recent commits and repository branding, noting that recent commits are a particularly strong indicator of AI authorship.

The experiment was conducted on a batch of one hundred and two applications pushed to F-Droid on September 12, 2026. The results showed that a significant majority were influenced by AI, with seventy-four applications (seventy-two point five percent) exhibiting heavy LLM involvement. The remaining items showed little to no discernible AI presence (seventeen point six percent), and a minority were categorized as difficult to assess (nine point eight percent). The author notes remaining cautious about the robustness and maintainability of the observed AI-generated code, though they maintain that most findings are accurate.

Many of the applications analyzed displayed specific patterns indicative of LLM use. For instance, several projects, including Amber, Balance, Baly Groceries Tracker, BayesianBahn, BlockDrop, Braincup - Brain Training, and many others, were classified as Mostly AI due to code and commit artifacts suggesting LLM involvement, such as the use of Claude Code or Codex infrastructure in their contributions. Other applications, such as Aria for Misskey and Aves Libre, were rated as having No signs of AI, although the author admits this is a difficult assessment.

Specific attention was given to repositories where the presence of LLM infrastructure was explicitly noted, such as DeltaSync, evcc - solar charging, and PingOff, where commits were co-authored by Claude. Conversely, some projects, like Mako and ReadBear, were rated as Mostly Human, suggesting a more mixed contribution style within the FOSS community. The findings also highlighted some peculiar developments, such as the presence of apps branded with “Don’t tread on me,” and the bizarre development practices of some maintainers who utilized the GitHub web file editor instead of standard git workflows.

In conclusion, the experiment, while lacking a formal code quality analysis, provides a metric for the influence of LLMs on the FOSS landscape. The author expresses a conflicted sentiment, recognizing the utility of the software while simultaneously voicing concern about the potential negative effects of widespread AI-driven development on the open-source community and the integrity of human-driven engineering.
