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?.

Terminal Emulators

Name Alternative(s) Evidence Notes
Warp Advertised as an "agentic development environment."

Developer Tools

Name Alternative(s) Evidence
cargo-nextest Just use cargo test CLAUDE.md and AGENTS.md in repository

Programming Languages

Name Alternative(s) Evidence Notes
.NET See below .NET Runtime PRs, .NET SDK PRs
Julia Python (w/ appropriate scientific libraries) AGENTS.md in main repository, PRs "written by Claude"

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 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 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

Accessibility Tools

Name Alternative(s) Evidence Notes
espeak-ng flite Dev uses copilot for review and is setting up copilot instructions espeak still exists, but is heavily outdated and very bad from a modern standpoint, so it cannot be considered as an alternative. flite users may also wish to install speech-dispatcher-flite.

Service Monitoring

Name Alternative(s) Evidence
Uptime Kuma Gatus Dev uses copilot for review

Libraries

Rust

Name Alternative(s) Evidence Notes
facet Use more specific deserialization libraries and avoid macros that slow things down anyway. serde itself is tainted by its Palantir-defending author. nanoserde could be suitable for certain use cases. Core developer openly uses LLMs for library dev
ratatui iocraft and cursive. console and its family of libraries may also be enough for some use cases. Core developer has stated their use of AI for rust code

Also, there is an advistory database of Rust slopware crates, which you can use in tools like cargo-deny: https://codeberg.org/erin/rust-slopdb.

Why not LLMs?

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

  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.
