24 alternatives to 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…

Mathematica is an incredible piece of software, and the Wolfram Language is actually quite pleasant to use once you get used to the syntax. Unfortunately, the high licensing costs of Mathematica make it inaccessible to many people, and therefore (in my opinion) worse solutions like Python, R, and Jupyter have become the default. Due to the sheer size of Mathematica (over 6000 functions!), it is impossible for me to rebuild it from scratch alone. Please join me in rebuilding it one PR at a time so we can finally make it accessible to everyone!

Hey HN I’ve been building *W++*, a scripting language that looks like Python but runs on the .NET runtime. It started as a fun side project, but it evolved into something surprisingly powerful — and potentially useful: Key Features: - Python-style syntax with semicolon-based simplicity - Compiles to .NET IL with experimental JIT support - Can run interpreted or compiled - Built-in CLI for managing projects, running, and building - Supports importing NuGet packages and converts them to .ingot modules automatically - MIT licensed and fully open-source You can even do things like: wpp import…

WOZCODE▲194For the last year we've been building an AI mobile app builder. Last week we decided to generalize our agent harness and benchmark it against vanilla Claude Code. Turns out the tools we built for app building were significantly more efficient than the native Claude Code tools. When we ran benchmarks we beat Claude code on speed (~40% faster) , cost (25-55% cheaper) and performance (+17% on Terminal Bench 2.0). Today we're making our agent harness publicly available as a Claude Code plugin. Use code WOZCODE1 to try it for $1 at wozcode.com

Hi HN! I've been working on a code editor and I think that it's mature enough to catch some interest. It's using a custom GPU accelerated GUI written in C++. Currently implements some interesting features: LSP, terminal, auto-completion, linters, formatters, custom keybindings, plugins and more. It's a hobby project but still intends to be an alternative to other popular code editors like Sublime, Kate, Lapce, Lite XL (and takes inspiration from them). The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but…

I usually build web games in C++, but using Emscripten always felt like overkill for what I was doing. I don't need full POSIX emulation or a massive standard library just to render some stuff to a canvas and handle basic UI. The main thing I wanted to solve was the JS/WASM interop bottleneck. Instead of using the standard glue code for every call, I moved everything to a Shared Memory architecture using Command and Event buffers. The way it works is that I batch all the instructions in WASM and then just send a single "flush" signal to JS. The JS side then reads everything directly out…

Hi HN! Langfuse is OSS observability and analytics for LLM applications (repo: https://github.com/langfuse/langfuse, 2 min demo: https://langfuse.com/video, try it yourself: https://langfuse.com/demo) Langfuse makes capturing and viewing LLM calls (execution traces) a breeze. On top of this data, you can analyze the quality, cost and latency of LLM apps. When GPT-4 dropped, we started building LLM apps – a lot of them! [1, 2] But they all suffered from the same issue: it’s hard to assure quality in 100% of cases and even to have a clear view…

We needed a JS-first WYSIWYG DOCX editor and couldn't find a solid OSS option, most were either commercial or abandoned. As an experiment, we gave Claude Code the OOXML spec, a concrete editor architecture, and a Playwright-based test suite. The agent iterated in a (Ralph) loop over a few nights and produced a working editor from scratch. Core text editing works today. Tables and images are functional but still incomplete. MIT licensed.

I've built many interpreters over the years, and Bolt represents my attempt at building the scripting language I always wanted. This is the first public release, 0.1.0! I've felt like most embedded languages have been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world. Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance. I intend to be…

Hi! I’m Nathan: an ML Engineer at Mozilla.ai: I built agent-of-empires (aoe): a CLI application to help you manage all of your running Claude Code/Opencode sessions and know when they are waiting for you. - Written in rust and relies on tmux for security and reliability - Monitors state of cli sessions to tell you when an agent is running vs idle vs waiting for your input - Manage sessions by naming them, grouping them, configuring profiles for various settings I'm passionate about getting self-hosted open-weight LLMs to be valid options to compete with proprietary closed models. One…

Hey HN, I made Browser-Use, an open-source tool that lets (all Langchain supported) LLMs execute tasks directly in the browser just with function calling. It allows you to build agents that interact with web elements using natural language prompts. We created a layer that simplifies website interaction for LLMs by extracting xPaths and interactive elements like buttons and input fields (and other fancy things). This enables you to design custom web automation and scraping functions without manual inspection through DevTools. Hasn't this been done a lot of times? Good question, as a general…

Hi everyone, we’re a small team, supported by Mozilla, who are working on re-imagining a UI for training, tuning and testing local LLMs. Everything is open source. If you’ve been training your own LLMs or have always wanted to, we’d love for you to play with the tool and give feedback on what the future development experience for LLM engineering could look like.
