The score comes from our model.

• Show HN: Dolly – A Tribute to "The Birth and Death of JavaScript" · score 7.3

  Dolly is a browser-hosted operating environment that emulates a POSIX-like system with a package manager, compiler toolchain, X server, and numerous applications including coding agents and WebGPU-rendered games. It's a remarkable technical feat, bootstrapping complex software like LLVM, Emacs, and Neovim entirely within a web page, but the documentation is just a terse package list without installation or usage instructions.

• Show HN: Cactus Needle – Local tool calling and speech-to-text in JavaScript · score 6.8

  Cactus Needle is a JavaScript/TypeScript library that runs the Needle and Whistle models locally in the browser or Node.js via WebAssembly. It provides tool calling, structured extraction, text embeddings, and speech-to-text without API keys or servers, offering both a standalone API and an optional Vercel AI SDK provider.

• Show HN: Yavashark: I've Built a JavaScript Engine Every Day for 950 Days · score 5.8

  Yavashark is a from-scratch JavaScript engine written in Rust, currently passing ~82% of the test262 suite and supporting Temporal, Intl, TypeScript, and React. It is notable for its single-developer dedication (950 days), easy Rust-to-JS binding via macros, and plans for a reusable garbage collector.

• Show HN: Turn regular JavaScript into a neural net · score 5.7

  Handwired is a tool that transforms regular JavaScript code into a neural network, demonstrated by rendering a mini desktop OS entirely through a neural net to DOM. It explores a novel paradigm of compiling imperative code into learned weights, but lacks documentation and clear practical applications.
