# Open Slopware

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 this technology's usage in popular software, as well as give people informed alternatives that they can reach for when they want to make decisions for themselves. This is not a list created so you can go and give these projects trouble for their decision. If you want to file a complaint about it with them, we consider that acceptable but ask that it be done respectfully and constructively.

For more information on why we think this list matters, please see [Why not LLMs?](#why-not-llms).

To Contribute, checkout our [`CONTRIBUTING.md`](./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.

#### 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 or Scala may be interesting candidates from the perspective of being similar VM-based frameworks, while Python or Rust may be interesting alternatives in other ways.

### Editors

| Name | Alternative(s) | Evidence | Notes |
|---|---|---|---|
| [Zed](https://zed.dev) | [Lapce](https://lap.dev/lapce/), other popular editors like neovim, 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](https://code.visualstudio.com/) | [VS Codium](https://vscodium.com/)* removes the AI _features_ from VS Code | [It's literally their main advertising tagline](./img/vscode.png), and they publicly use LLMs in [their public repository](https://github.com/microsoft/vscode/pulls). Most AI "features" are enabled by default, and some cannot be disabled. | *VS Codium is still written with LLMs since Microsoft owns it |

### Accessibility Tools

| Name | Alternative(s) | Evidence | Notes |

## Why not LLMs?

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

### Legal Ramifications

1. 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.

### Environmental Impact

To start learning a bit more, you can checkout the wikipedia page on [Environmental impact of artificial intelligence](https://en.wikipedia.org/wiki/Environmental_impact_of_artificial_intelligence#Individual_level). We're very open to people contributing other explanations, links, and resources to learn more about this.

### Poor Code Quality

Vibe coding results in poorer code quality and is compounded by having addition LLMs do the reviews of both bugs and pull requests in repos.

#### Healthy and Safety

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

- [AI Toy Exposed 50,000 Logs of Its Chats With Kids to Anyone With a Gmail Account](https://archive.ph/dX5xd)

- <details>
      <summary>Content Warning: Suicide</summary>

  - [Wikipedia: Deaths linked to chatbots](https://en.wikipedia.org/wiki/Deaths_linked_to_chatbots)
  - [AI chatbot pushed a teen to kill himself, a lawsuit against its creator alleges](https://apnews.com/article/chatbot-ai-lawsuit-suicide-teen-artificial-intelligence-9d48adc572100822fdbc3c90d1456bd0)

  </details>

#### 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:

- [Overrun with AI slop, cURL scraps bug bounties to ensure “intact mental health”](https://arstechnica.com/security/2026/01/overrun-with-ai-slop-curl-scraps-bug-bounties-to-ensure-intact-mental-health/)
