24 alternatives to Desktop Viewer for WebAssembly Modules
Hello there, I’m working on a desktop viewer application for WebAssembly modules for Windows, macOS, and Linux, and I’m looking to have some feedback from real-world use. The application is fairly small, requires no installation for now, and is limited to the minimum functionality, but I have more features in mind for the future. Testers would get a free license including future releases. If you’re interested, drop me a mail at [email protected] with the platform(s) you could test on. It would be helpful if you could tell me about in what capacity do you work with WebAssembly,…

Hey HN! I've been working on a book about WebAssembly over the last few months, and it's finally available at http://levelupwasm.com! Why a book on WebAssembly you ask? Well... WebAssembly is awesome (obviously ) but it's certainly not the easiest thing to learn. So I wrote this book as a practical intro to using WebAssembly in your web apps. I would appreciate any feedback!

Hi, I'm a developer and first time i shipped the real product after observing the startups and indie hackers community for years. I had made so many useless apps [you should check my website https://ansh.life], but this time I built a very useful product that has a number of super easy-to-use tools in one app for video, music, and photo files. Users can compress, convert, resize, and do so much more with easy-to-use tools. Background: I developed a frame-by-frame video cropper to upload cropped landscape videos to Instagram Reels. However, it required FFmpeg, and as a noob video…

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…

Hi HN! I’m Syrus, from the Wasmer team. We just released the new version of WAPM that is an order of magnitude better than the previous one (that we also announced here in HN two years ago! [0]), enabling an incredible experience for using and publishing WebAssembly packages. The tech stack that we are using includes: * Python and Django (for the backend) with Graphene (for the open GraphQL API [1]) and Django Channels with websockets over GraphQL [2] for subscriptions * Next.js [3] with React-Relay [4] and Tailwind.css [5] for the frontend * WebAssembly and Wasmer [6] (for the online shell)…

Show HN: TinyWasm - A tiny WebAssembly Runtime written in Rust Hi HN! I'm excited to share TinyWasm (https://github.com/explodingcamera/tinywasm), a WebAssembly Interpreter I developed for my final university project. The main goal of this project was to deepen my understanding of WebAssembly and interpreter design. TinyWasm successfully passes all the official WebAssembly 1.0 tests and also includes features from future proposals such as like bulk memory operations. Initially more of a research project, TinyWasm focuses on simplicity and portability. It has minimal…

I've been building open-source tools in the video/multimedia space for 10+ years. Finally shipped the commercial product I always wanted to exist — Video Commander, a desktop app that consolidates FFmpeg, ffprobe, MediaInfo, VMAF and more into a single workspace where you can inspect, encode and analyze video. Built with Tauri + Rust backend, React frontend. FFmpeg and VMAF. Not a cool AI/LLM project, just a tool I've been heads-down building over the last six months. Happy to answer any questions!

Hi HN, I just wanted to share what I have been working on for the past few months: A firmware analyzer for embedded Linux systems that helps uncovering security issues running entirely in the browser. This is a very early Alpha. It is going to be rough around the edges. But I think it provides quite a lot of value already. So please go ahead and drop a firmware (only .tar rootfs archives for now) and try to break it :)

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://luna-demo.vercel.app

Hello HN, I've always found Screen Studio recordings superb. Unfortunately I'm not on a Mac, so I've developed my own tool that works in the browser for all OS. I hope you'll find it useful, and I'd be delighted to hear your feedback.

Hello all, I've been working on research tools for Wasm for some time now, and just today we put up the pre-print for our newest paper "Flexible Non-intrusive Dynamic Instrumentation for WebAssembly" (https://arxiv.org/abs/2403.07973), which will appear in ASPLOS 2024. Two previous papers, one about Wizard's interpreter (https://dl.acm.org/doi/10.1145/3563311) and one about the JIT (https://arxiv.org/abs/2305.13241) have been discussed on HN before. This new paper explains what Wizard is really about: dynamic instrumentation of…

Just something I put together quickly: https://webcast.browserprotect.me/ I made this in one day, now I'm wondering if It's interesting enough to make it a real product (Add new features like setting the size, zoom, annotations, fix bugs, export, voice-over, etc..) Here is an example screencast I just did: https://webcast.browserprotect.me/view/2764aa94dcd855959819fd91881f0882baa61a0e-44646 Do you consider this a viable product? I'm thinking about offering it for free and then add some premium features.
