24 alternatives to Crazierl – An Erlang Operating System
Crazierl is an experimental/hobby operating system based around BEAM. I've linked the browser based demo; I don’t recommend using a phone; it does work, slowly, on the phones I tested, but it’s very awkward to use. You can share a link with a hashtag with your friends and click the consent checkbox, and it (should) link up into dist and I’ve also included a chat application you can start with chat:start(). (quit chat with /quit, or use the shell menu with ctrl-g to switch between shells etc). The browser demo relies on the v86 javascript x86 virtual machine. You can also run…
Crazierl is an experimental hobby operating system built on BEAM, the Erlang runtime. It runs in a browser-based demo powered by a JavaScript x86 virtual machine, or on real 32-bit x86 hardware with BIOS boot.

Hey HN, this is a small project myself and closer friends have been building on our free time (https://github.com/Dr-Nekoma/lyceum), it finally reached 0.1.0, we are open to feedback! The original idea was to experiment with Zig + Raylib, eventually we wrote a small server in Erlang as well. We started by first interacting with Erlang via its C bindings, but this eventually led to some of us to prototyping our own tooling to better integrate Zig types with Erlang, we called such tool "zerl" as its avaliable here…

Using threaded emscripten to speed up the generation and offload the main loop. No SIMD or other optimizations. Might work faster with #enable-experimental-webassembly-features enabled.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…

I spent the last few days building out a nicer ChatGPT-like interface to use Mistral 7B and Llama 3 fully within a browser (no deps and installs). I’ve used the WebLLM project by MLC AI for a while to interact with LLMs in the browser when handling sensitive data but I found their UI quite lacking for serious use so I built a much better interface around WebLLM. I’ve been using it as a therapist and coach. And it’s wonderful knowing that my personal information never leaves my local computer. Should work on Desktop with Chrome or Edge. Other browsers are adding WebGPU support as well - see…

Hi There, Erlang-RED has been my project for the last couple of months and I would love to get some feedback from the HN community. The idea is to take advantage of Erlangs message passing and low overhead processes to have true concurrency in Node-RED flows. Plus also to bring low-code visual flow-based programming to Erlang.

QuickBEAM is a JavaScript runtime embedded inside the Erlang/OTP VM. If you’re building a full-stack app, JavaScript tends to leak in anyway — frontend, SSR, or third-party code. QuickBEAM runs that JavaScript inside OTP supervision trees. Each runtime is a process with a `Beam` global that can: - call Elixir code - send/receive messages - spawn and monitor processes - inspect runtime/system state It also provides browser-style APIs backed by OTP/native primitives (fetch, WebSocket, Worker, BroadcastChannel, localStorage, native DOM, etc.). This makes it usable for: - SSR…

Run `ssh devzat.hackclub.com` to try it out! The repo is here: https://github.com/quackduck/devzat (golang). It has markdown and emoji support, DMs, channels, and it can show images too. You can send code, and it gets syntax highlighted (you can change the theme). You can ping people like so: @user and it sends them a \a, which should play an audible sound if the terminal allows it. There's inbuilt games and rainbow names and a lot of other small things I don't remember right now. You might find the auth system interesting: it's based on a hash of ssh pubkey (bans use…

I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

Earlier this year, we released our open-source game engine [0] built with Rust, WebAssembly, and WebGPU. Today, we’re happy to announce the Ambient platform, which brings web deployment, server hosting, and more to the runtime. With Ambient, you can make a game, deploy it to the browser in one command, share your URL and instantly play with others, no downloads or installs needed. Our WASM use is innovative; it is being used as both a sandboxed runtime for user code, and as a way to run the entire Ambient runtime in the browser. This, paired with our ECS data model, enables a highly modular…

Hello! This is the most useless thing I did in quite some time, but it was fun. Compile erlang (actually BEAM) to wasm, statically link with a small http wrapper and run as a request handler under wasmtime. This is not very practical as of now and you better just compile atomvm and statically link it with erlang payload if you really need to run erlang on the edge node (you don't). When (if) typed continuations become a thing, this should also allow for erlang actor model.

Hi HN, I'm working on an Erlang inspired WebAssembly runtime for the backend[0]. Recently I added TCP support and was looking for apps I could build with it. I ended up building a telnet line chat app. It was a great dogfooding experience and has a nice retro feel to it. You can access the US server with > telnet lunatic.chat or the EU one with: > telnet eu.lunatic.chat You should pick the one closer to you as all the rendering is done on the backend and lower latency will mean better UX. The server is open source[1] and written in Rust. The Rust code is then compiled to WebAssembly and runs…
