24 alternatives to Munal OS: a graphical experimental OS with WASM sandboxing
Hello HN! Showing off the first version of Munal OS, an experimental operating system I have been writing in Rust on and off for the past few years. https://github.com/Askannz/munal-os It's an unikernel design that is compiled as a single EFI binary and does not use virtual address spaces for process isolation. Instead, applications are compiled to WASM and run inside of an embedded WASM engine. Other features: * Fully graphical interface in HD resolution with mouse and keyboard support * Desktop shell with window manager and contextual radial menus * PCI and VirtIO…
Munal OS is an experimental operating system written in Rust that uses a unikernel architecture compiled as a single EFI binary. Instead of traditional virtual address spaces, it isolates applications by running them… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

To try it out, simply build the project yourself from source, or use attached bootable ISO image of the system (in Releases on Github) and run it in QEMU. https://blog.vxn.dev/rou2exos-rusted-edition

I'm excited to introduce Zerobox, a cross-platform, single binary process sandboxing CLI written in Rust. It uses the sandboxing crates from the OpenAI Codex repo and adds additional functionalities like secret injection, SDK, etc. Watch the demo: https://www.youtube.com/watch?v=wZiPm9BOPCg Zerobox follows the same sandboxing policy as Deno which is deny by default. The only operation that the command can run is reading files, all writes and network I/O are blocked by default. No VMs, no Docker, no remote servers. Want to block reads to /etc? zerobox…

I wanted to see how fast an isolated code sandbox could start if I never had to boot a fresh VM. So instead of launching a new microVM per execution, I boot Firecracker once with Python and numpy already loaded, then snapshot the full VM state. Every execution after that creates a new KVM VM backed by a `MAP_PRIVATE` mapping of the snapshot memory, so Linux gives me copy-on-write pages automatically. That means each sandbox starts from an already-running Python process inside a real VM, runs the code, and exits. These are real KVM VMs, not containers: separate guest kernel, separate guest…

This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality. At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root…

Shuru is a lightweight sandbox that spins up Linux VMs on macOS using Apple's Virtualization.framework. Boots in about a second on Apple Silicon, and everything is ephemeral by default. There's a checkpoint system for when you do want to persist state, and sandboxes run without network access unless you explicitly allow it. Single Rust binary, no dependencies. Built it for sandboxing AI agent code execution, but it works well for anything where you need a disposable Linux environment.

VEKOS(Verified Experimental Kernel OS) is a Rust-based experimental kernel that focuses on runtime verification and security. Every filesystem operation and memory allocation generates cryptographic proofs that can be verified in real-time, ensuring system integrity. Think of it like a blockchain for OS operations rather than just storage verification. Key features: - Merkle tree-backed filesystem with operation verification - Memory manager with CoW and proof generation - Buddy allocator with zone-based memory management - Shell with VT100 support - Verified boot sequence with stage…

Hi HN! I'm 13 and I built Aurion OS as a solo learning project over 14 days (~12 hours/day). It's a 32-bit x86 operating system written entirely in C and x86 Assembly with no external libraries. What it has: Custom bootloader and kernel VESA framebuffer graphics (1920x1080, double-buffered) Window manager with draggable, overlapping windows macOS-inspired dock with transparency PS/2 keyboard and mouse drivers ATA hard drive driver with filesystem PCI bus enumeration RTL8139 network driver (WIP) Real-time clock Runs on just 16MB RAM (up to 10 windows simultaneously) Built-in apps:…

Hi HN, I’m Dvir, a young developer. Last year, I got rejected after a job interview because I lacked some CPU knowledge. After that, I decided to deepen my understanding in the low level world and learn how things work under the hood. I decided to try and create an OS in C and ASM as a way to broaden my knowledge in this area. This took me on the most interesting ride, where I’ve learned about OS theory and low level programming on a whole new level. I’ve spent hours upon hours, blood and tears, reading different OS theory blogs, learning low level concepts, debugging, testing and working on…

"Game" is a stretch, but I put together this repo containing a pure Rust app which uses SDL2 and compiles to WASM (and can be run in a browser). Older resources were a bit out of date and a bit too verbose for my purposes, so here's a minimal working example.

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…

I built GRSH because I wanted a modern, memory-safe shell that feels native to FreeBSD but works seamlessly on macOS. While there are many shells out there, GRSH is my take on a minimal, fast, and secure command interpreter written entirely in Rust. It's designed for users who want the safety guarantees of Rust without the overhead of more bloated alternatives. I'm currently working on the official FreeBSD port. I’d love to get feedback on the shell's behavior and performance from the community. Github: https://github.com/antoniomalara301289/grsh

I built this because I was always creating machines on GH actions to test builds on different OS, and I wanted a tight CLI that could do it. I always saw Actions as this great resources and ephemeral machines you could do dev work in just were a natural way for me to work, so this grew out of that workflow. I didn't expect it to blow up, so it wasn't 100% finished when I posted it. But it should stabilize pretty quickly. Happy to know what you think and talk about it.
