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

|---|---|---|---|
| VS Code opens in a new tab | VS Codium opens in a new tab * removes the AI features from VS Code | It’s literally their main advertising tagline , and they publicly use LLMs in their public repository opens in a new tab . Most AI “features” are enabled by default, and some cannot be disabled. | *VS Codium is still written with LLMs since Microsoft owns it |
| Zed opens in a new tab | Lapce opens in a new tab , 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. |
