Open Source Rust System Software

RebornOS is an Arch Linux based distribution whose goal is to make Arch Linux more approachable to beginners. We stick close to Arch Linux, offer choices without much bloat, and we provide quite a bit more support and handholding than typical distributions so that beginners don't feel overwhelmed.

Velox — Segmented Download Manager Velox is a fast, modern, open-source download manager for desktop (macOS / Windows / Linux). Built with Tauri 2 + Rust and a React/Tailwind UI, it downloads files dramatically faster than a browser by splitting each file into parallel byte-range segments and fetching them simultaneously — the same technique used by IDM. Features - Segmented downloading — splits files into up to 32 parallel connections and assembles them byte-perfectly. Tune the connection count per download or globally. - Pause / resume— pause any download and pick it back up exactly where it left off, byte-for-byte (works on any server that supports HTTP byte ranges). - Crash-safe resume— Velox writes your progress to disk every few seconds with atomic writes, so an app crash, power loss, or reboot never costs you your progress. In-progress downloads are auto-resumed on launch. - Download history — every download is recorded in a local SQLite database

v86 is an open-source x86 PC emulator that runs entirely in the browser using WebAssembly for near-native performance. It translates x86 machine code into WebAssembly at runtime, enabling users to boot and run full operating systems without installing anything locally. The emulator supports a wide range of legacy systems, including Linux, Windows 95/98/2000, FreeDOS, and various experimental OSes. It simulates essential hardware components such as CPU, memory, VGA graphics, sound cards, network adapters, and storage controllers. Designed for both experimentation and embedding, v86 can be integrated into web apps or used as a standalone virtual machine environment. Overall, it provides a powerful way to explore operating systems, retro computing, and low-level system behavior directly from a web browser.

MangoDisk is a free, open-source disk cleaner for Windows, macOS and Linux. Find caches, large files, exact duplicates and app leftovers without digging through hidden folders. Explore disk usage with nested treemaps or a sunburst chart to see which folders take up the most space. Privacy Cleanup lets you review supported browser, app and system activity by time range. Clearing cookies can sign you out of websites. Also included: app uninstall, startup management, system optimization, common repair tools and an operation history. The resource panel shows CPU, memory, network and disk activity. Scans run locally and don't delete files. Choose what to remove and confirm before cleanup. No signup or login is required. Unsure about a file or an app? Optional online AI explanations cover cleanup items, startup entries, large files, duplicates and app uninstall. They explain purpose, impact and cautions; they don't delete files or replace your judgment.

NebiOS is an Ubuntu LTS-based Linux distribution with a custom desktop environment (NebiDE), built by one person. It combines a unique visual identity (Flat-Skeuomorphism), a widget-first desktop, and its own app format (.napp) into a cohesive platform — not just another reskin. Official mirror — use if the main site has download issues. Main site: https://nebios.org 📌 This mirror page is updated less frequently than the main site.

Most hypervisors (VirtualBox, VMware, GNOME Boxes) will show degraded performance. QEMU with 3D acceleration enabled gives the best VM experience. See FAQ for details.

LocalDomain is a desktop application that simplifies local development by letting you create and manage custom local domains. It handles hosts file entries, generates trusted SSL certificates via a local CA, manages a reverse proxy (Caddy) daemon, and provides access/audit logging — all through an intuitive GUI. Built with Tauri, React, and Rust.

IsuDeck by rootcf is a free, high-performance, and open-source desktop studio that repurposes any spare secondary USB keyboard, wireless numpad, or macro keypad into a fully isolated control console. While commercial macro consoles cost hundreds of dollars with limited physical keys, IsuDeck unlocks 104+ macro keys from hardware you already own with ZERO additional hardware cost. Standard Windows behavior merges all attached keyboards into one input stream. IsuDeck uses a low-level Interception kernel filter driver to isolate your secondary keyboard by its unique Hardware ID (HID). Keystrokes are swallowed at the OS level before reaching games, documents, or active windows—leaving your main keyboard and gameplay 100% uninterrupted.

High-throughput serial capture without dropped data. Real-time plotting and visual inspection of incoming data. Combined ASCII / HEX views suitable for low-level debugging. Multi-window workflows for parallel monitoring. Cross-platform support (Windows, Linux).
