   Firefox in WebAssembly▲273

   This is the entire Firefox browser rendering to a element. Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly. Here are a few things you might find interesting: - This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets. - There is a novel WASM->JS JIT for experimental site speedup - This port cost over 25k in opus/fable tokens for debugging and JIT research This was just a fun experiment to push the boundaries of WebAssembly. For a more usable "browser in browser" experience, we also built…

   Dropbase – Build internal web apps with just Python▲207

   Hey HN, I’m Jimmy, co-founder of Dropbase (https://www.dropbase.io). We are an internal tools builder for Python developers. All you have to do is import any Python scripts/libraries, declare UI components, and layer app permissions so you can share them with others. We’re a middle ground between Airplane and Retool—simpler UI creation than Airplane, more code-centered than Retool. UI building is declarative and you can bind Python scripts/functions to UI components. You can write Python scripts/functions using our App Studio with support from a Python Language…

   W++ – A Python-style scripting language for .NET with NuGet support▲98

   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…

    I built a small browser engine from scratch in C++▲146

    Hi HN! Korean high school senior here, about to start CS in college. I built a browser engine from scratch in C++ to understand how browsers work. First time using C++, 8 weeks of development, lots of debugging—but it works! Features: - HTML parsing with error correction - CSS cascade and inheritance - Block/inline layout engine - Async image loading + caching - Link navigation + history Hardest parts: - String parsing(html, css) - Rendering - Image Caching & Layout Reflowing What I learned (beyond code): - Systematic debugging is crucial - Ship with known bugs rather than chase…

    CodeLink: create links to blocks of code in your IDE▲89

    Small team down here in South New Zealand just launched CodeLink. In short its an IDE (VSCode&#x2F;JetBrains) plugin that lets you share blocks of code that link directly to the code inside your IDE or repo. We use it all the time and think its pretty nifty tech that lets you understand someone’s code in context very quickly. we’re hoping to keep refining it to make it better and more useful.

    Wrote a tiny WebAssembly (wat2wasm) compiler in Go▲75

    As a personal project I wrote a really tiny Wat 2 Wasm compiler in Go. Mainly for demonstrative and educational purposes. It was tough: I didn't know anything about WebAssembly internals and I'm a newbie with Go... so I tried to document it as much as I could for anyone that would like to approach the quest in the future! It misses a lot of features (that will be gradually implemented). Any feedback is welcomed!! Demo: https:&#x2F;&#x2F;luna-demo.vercel.app

    A C/C++ IDE written in C from scratch with zero dependencies▲10

    I’ve spent the last ~2 years building a C&#x2F;C++ IDE for Windows entirely in C99. My goal was to eliminate the bloat of the modern Visual Studio environment keeping its core features. Key Technical Highlights: Zero Dependencies: Just the Windows API Performance: Starts in 0.1ms on a twelve year old machine. It handles projects with 500k+ lines without UI lag or indexing stutters. Integrated Tools: Includes a custom-built debugger, profiler, and Intellisense engine designed for speed. Portability: It’s a single executable. No installer required. I built this because I was tired of waiting…
