Products that do what Waputer – The WebAssembly Computer does
Waputer is an operating system that runs entirely in the browser. When you visit the website at https://waputer.app, a kernel written in JavaScript sets up a filesystem and launches a WebAssembly program, which in turn talks to the kernel to handle the display and input. A purely terminal-based version is at https://waputer.dev. My original intention was to create programs that run in the browser that have a lot more in common with the desktop. The traditional "hello world" program is not really suited for the web. Waputer changes that. The GitHub repo at…

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,…

Hi HN! We (pdubroy & marianoguerra) just launched an online book called WebAssembly from the Ground Up. It's an online book to learn Wasm by building a simple compiler in JavaScript. This is the book we wish we'd had 3 years ago. Unlike many WebAssembly resources that focus on use cases and tooling, we wanted a deep dive into how Wasm actually works. We focus on the core of WebAssembly: the module format and the instruction set. We think the low-level details — the "virtual ISA" — are the most interesting part, and we had the crazy idea that writing a compiler is the best way to learn it.…

I built a small demo showing a robotics runtime executing entirely inside the browser via WebAssembly. The example workload is a simple flight controller hooked up to a small world simulator. The runtime comes from copper-rs, an open-source robotics runtime written in Rust for deterministic workloads. While robotics stacks are often tightly coupled to specific OS distributions and environments, here, the same code runs on microcontrollers (for example this flight controller also compiles for STM32H7 and flies real drones) as well as on desktop OS targets like Linux, macOS, and Windows. The…
