Free/Open Source Software tainted by LLM developers/developed by genAI boosters, along with alternatives.

The intention of this list is to raise awareness of AI/LLM usage in popular open-source software. Provided below is an informed set of AI-free alternatives for users and developers to consider should their ethical boundaries be crossed or tolerance for risk be exceeded. This list is not a resource to be used for the harassment of other open-source developers. If you wish to advocate for the cessation of use and/or removal of AI-generated code from another project, we ask that it be done respectfully and constructively.

For more information on why we think this list matters, please see Why not LLMs?.

To Contribute, checkout our CONTRIBUTING.md.

Note

This is a fork of a repo by the same name maintained by the @gen-ai-transparency org on Codeberg. If they make their repo available again, we will contribute back.

Definitions

Term Definition
LLM Large Language Model, a language model trained on vast amounts of text (often entire websites without the website owner's permission)
slop Anything generated by AI, typically code, books, articles, or images.
sloperator A person who uses AI prompts to generate anything, typically code or images.
slopshop Company, Organization, or Group of sloperators working together to use AI to generate content.

Sibling Repos

This is a section for repos that are similar to this one either because they are also forks of the original upstream, or because they align with our goal of idenitifying and avoiding AI/LLM usage OR identifying/elevating projects that do NOT use AI/LLMs. These repos are not all maintained by the same people, but we may share some contributors and generally be kind FOSS nieghbors.

  • llm-afflicted-software offers a similar list to ours here, however in YMAL file format for each category, making it more suitable to consumption via code (for instance writing a CLI, GUI, or TUI tool to consume it). They've also kindly reached out in the past and submitted Issues and PRs (e.g. #12, #22) to help us here.
  • forge.starlightnet.work/Team/No-AI/ which is the repo for this no-AI list that lists projects that have explicitly pledged not to use AI or have an explicit policy to not use AI.
  • slop-free-index is a list of software that has taken steps to reject AI in its development processes.

Note

On alternative languages:

Suggestions for alternative programming languages are necessarily more complex than many other categories considered here, as that's one of the core technical choices to be made when starting a new software development project.

Depending on your needs and technical concerns, you may find any number of different alternative languages useful. For example, when considering alternatives to .NET, Java may be an interesting candidate from the perspective of being a similar VM-based framework.

Editors

Name Alternative(s) Evidence Notes
Zed Lapce, Gram (removes AI integration, codebase may still contain AI code), other popular editors like emacs, etc They prominently advertise genAI features as a core part of their product. See their website. There's a killswitch to disable genAI features entirely, but it's likely the code itself is still heavily LLM-authored.
VS Code VS Codium* removes the AI features from VS Code It's literally their main advertising tagline, and they publicly use LLMs in their public repository. Most AI "features" are enabled by default, and some cannot be disabled. *VS Codium is still written with LLMs since Microsoft owns it
VIm emacs, EVi and other forks of VIm prior to March 20th 2024, build v9.1.0190 or commit 8950bf7f8b85c1287d4e696965d88091fcc60594. Thread on Hachyderm.io where screenshots show that the lead maintainer, chrisbra, uses Claude for VIm including commits featuring Claude in the VIm repo and other potential LLM code from a contributor as early as March 2024. This also affects neovim and many other forks.

Why not LLMs?

Could use some help writing this with concrete receipts on environmental, social, political, and economic/labor harms.

LLMs are often trained on, and thus prone to, regurgitate either completely, or in-part, chunks of code that are licensed under terms which have specific legal requirements that a sloperator may not understand or even be aware of when making a contribution. Regardless of this ignorance, it falls to the repo's owner to comply with the terms of any and all licensed code integrated into their project.

License Problems

Legal, copyright and ethic problems arise especially with copyleft licenses such as (A/L)GPL. With the "help" of AI the copyleft code may be "license-washed" very easily.

There are ongoing problems with AI "license-washing" in the FOSS world:

Stolen Training Data

AI companies use data from across the web for training their models, most often without the website owners' and users' consent. Big tech companies like Google and Meta are scraping data from the users of major FOSS projects, such as Mastodon, WordPress, and other AcitivityPub-powered and self-hosted software.

  • In 2023, the Washington Post published a list of sources in Google's C4 data set. A multitude of fediverse instances and personal sites were included. The fediverse is known for its userbase being major proponents of privacy and opt-in consent, making this especially jarring for those who have chosen to use decentralized social media for control over their data.
  • In 2025, a similar leak of Meta's sources was published. Meta's list demonstrates how their integration of ActivityPub into their Threads software has enhanced their ability to mine content without authorization. Threads is widely blocked in some parts of the fediverse, but their scraping of server CDNs has allowed them to get around that. Notably, both the CDN domains of the managed hosting services masto.host and fedi.monster are included in the list; large servers like mastodon.art, which is hosted by the former and has many artists who've left sites like DeviantArt and others due to their AI scraping of user content, had media unknowingly scraped.

FOSS projects listed in this repo are using tooling that blatantly disregard licensing and violate of Codes of Conduct, making said tools antithetical to FOSS' purpose.

Environmental Impact

To start learning a bit more, you can checkout the wikipedia page on Environmental impact of artificial intelligence. We're very open to people contributing other explanations, links, and resources to learn more about this. Here's what we've gathered so far:

Labor

AI usage and normalization contributes to labor violations in many ways that are obvious and some you may not be aware of.

On one hand, many things that you think are "AI" are actually humans in another country pretending to be an AI chatbot for you for either extremely low wages or in some cases, no wages e.g. prison labor. This is particularly common for "friend"/"sex" bots, but it is also extremely common in the image/video identification. You can find a bit more info at the following links:

Poor Code Quality

Vibe coding / agentic workflows result in poorer code quality, and relaxed oversight practices. These effects may be compounded by the common practice of using additional LLM-based tooling to provide code-reviews.

Deskilling

There is increasing evidence to show that LLMs negatively impact developers' coding abilities:

Infosec risks

This also often results in massive security holes.

Healthy and Safety

There's been a number of high profile incidents that have resulted in endangerment or death. Here's some examples:

LLM use has also been linked to new-onset psychosis.

Ties to the War Industrial Complex

A lot of AI companies also work directly with nation states for use in their Departments of War (sometimes called Defense) which in turn leads to futher AI usage during war and invasions. This is coupled with NYT: Palantir, Anthropic and small start-ups are generating rewards from their investments in defense tech.

As another example NPR: OpenAI announced Pentagon deal after Trump banned Anthropic which was due to the USA Department of War launching an AI acceleration strategy.

Due to the nature of LLMs being only kind of as good as the data they are trained on, this can lead to additional civilian deaths and housing/infrastructure damage either intensionally or not. Examples:

Content Warning: War details, death

All of this to remind you that if you use AI, you're helping to support these companies and the additional activities they participate in, outside of generative code or images.

Effects on Policing

Police have quickly embraced AI, which has already directly led to people being jailed for things they've never done. As examples:

This is, in part, due to companies such as Amazon Aggressively pushing police to use AI which they do through both facial recognition and offering compute for predictive policing. With regards to facial recognition, here's an example of how it too can lead to false arrests: Face Recognition on Flawed Data.

There have been warnings about AI in policing, particularly around racial bias, such as:

Maintainer Fatigue

Having to deal with the onslaught of many LLM written pull requests and issues, causes real maintainer burnout that stagnates projects as maintainers become overwhelmed with half baked, poorly written, insecure code. Here's some examples:

Effect on Hardware Prices

The demand for construction and outfitting of new data-centers to host AI/LLM compute capacity has overwhelmed global supply and production of multiple hardware components. Memory, Storage, and GPUs have seen massive increases in price for both consumer and enterprise models upward of 400% in some cases.

The lack of supply has led large system-builders to purchase production capacity from OEMs well in-advance of delivery leading some manufacturers to end consumer-oriented product lines in favor of enterprise capacity.

The down-stream effects for consumers is that near all electronic devices which contain memory and storage will see their prices rise and availability decline. Those who already own existing electronics and computer hardware components may also find themselves unable to have their devices repaired or replaced under warranty.
