Woxi - Open-source Mathematica / Wolfram Language reimplementation
Woxi is an interpreter for the Wolfram Language written in Rust. It comes with Woxi Studio, a Mathematica-like GUI built with iced, but you can also use Woxi through a CLI, Jupyter kernel, Python package, npm package, or WASM module. Compared with wolframscript / Mathematica, the main differences are: - Free and open source - Very fast startup - Typically milliseconds rather than seconds for the Wolfram kernel, making Woxi practical for shell scripts, one-liners, and other short-lived processes - Embeddable - It can run in a browser via WASM or be embedded into another application as a…
In plain words
Woxi is an open-source Wolfram Language interpreter written in Rust. It provides multiple interfaces including Woxi Studio (a Mathematica-like notebook editor), command-line tools, Jupyter kernel, and browser-based playground, all running locally. Unlike Mathematica, Woxi starts in milliseconds rather than seconds, making it practical for scripts and short-lived processes, and can be embedded in browsers via WASM or other applications.

From the sources
Woxi is a Wolfram Language interpreter implemented in Rust. Run code in the browser playground, on the CLI, in Jupyter, or in the Woxi Studio notebook editor.
Everything runs locally in your browser. No data is sent anywhere. The playground above is one of several Woxi front-ends — the same interpreter powers a full-screen playground, a command-line tool, a Jupyter kernel (also runnable in the browser via JupyterLite), and a native notebook editor. Side-by-side editor and output pane with more room to explore. Great for multi-line expressions and experimenting with graphics. Evaluate expressions with woxi eval , run .wls scripts directly, or use Woxi as a shebang interpreter. Faster to start than wolframscript . Woxi ships as a Jupyter kernel. Install it locally with woxi install-kernel , or run the full notebook experience in your browser…from woxi.ad-si.com
In the maker’s words, at launch
Woxi is an interpreter for the Wolfram Language written in Rust. It comes with Woxi Studio, a Mathematica-like GUI built with iced, but you can also use Woxi through a CLI, Jupyter kernel, Python package, npm package, or WASM module. Compared with wolframscript / Mathematica, the main differences are: - Free and open source - Very fast startup - Typically milliseconds rather than seconds for the Wolfram kernel, making Woxi practical for shell scripts, one-liners, and other short-lived processes - Embeddable - It can run in a browser via WASM or be embedded into another application as a scripting language A more detailed comparison with Mathematica is available here: https://woxi.ad-si.com/docs/comparison/mathematica/. Conformance is ensured with ~26'000 unit tests and ~900 .wls script snapshot tests. The current focus is on fixing remaining edge cases, improving performance, and growing the community. If you use the Wolfram Language, I'd be particularly interested in feedback on compatibility and missing functionality. Contributions and bug reports are also very welcome: https://github.com/ad-si/Woxi

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
