HeroOS

A from-scratch operating system built as a genuine alternative to Windows.

Not yet available Documentation Roadmap
In Development · Phase 1 complete — kernel core with paging, heap, GDT/TSS, IDT, PIC/PIT and 10 passing self-tests. Phase 2 (keyboard, mouse, RTC, user mode) is next. HeroOS is a standalone OS, not a Minecraft mod.

See it in action

HeroOS v— — the real thing, not a mockup

No demo video — run it yourself

We do not publish mockups as proof of working software. This page describes build —: launch it, follow the tutorial step by step, or read the docs — every claim links to something you can execute today. Recorded walkthroughs are tracked on the roadmap.

Why it exists

Purpose

Windows ships ads, forced updates, and telemetry. HeroOS is a custom operating system built from scratch — own kernel, drivers, GUI, shell, and filesystem — designed to be fast, private, predictable, and owned end-to-end.

Who it's for

Developers, privacy-focused users, and anyone who wants a predictable OS without ads or telemetry.

Key capabilities

Own everything

Own kernel, drivers, GUI, shell, filesystem, and package manager.

Rust, no_std

A memory-safe kernel in Rust with minimal x86-64 assembly.

Bootable today

Boots to a boot banner and kernel logs; real hardware is a v1.0 goal.

Features

HeroOS — feature registry

5 features across 4 categories — 4 live, 1 planned. Every feature carries its real lifecycle.

Custom Kernel 2 features

Rust no_std kernel

A memory-safe kernel in Rust with minimal x86-64 assembly.

Phase 1 core

Paging, heap, GDT/TSS, IDT, and PIC/PIT with 10 passing self-tests, booting to a framebuffer boot banner.

UEFI Boot 1 feature

Boots today

Boots to a boot banner and kernel logs in an emulator; real-hardware boot is a v1.0 goal.

Own GUI 1 feature

Everything owned planned

Own kernel, drivers, GUI, shell, filesystem, and package manager — with a v1.0 desktop on the roadmap.

Privacy by Design 1 feature

No ads or telemetry

Built to be fast, private, and predictable — without ads, forced updates, or telemetry.

Quick start

Get started with HeroOS in minutes

Follow these steps — most installs take under five minutes.

1

Step 1

HeroOS is in development — there is no public build to install yet, and nothing runs on real hardware today.

2

Step 2

Understand where it is: Phase 1 is complete — kernel core (paging, heap, GDT/TSS, IDT, PIC/PIT) with 10 self-tests passing, booting to a framebuffer boot banner in an emulator.

3

Step 3

Follow the roadmap to track Phase 2 progress: keyboard, mouse, RTC and user mode — the next milestone.

4

Step 4

Plan around the later phases: driver framework (loadable kernel modules), then the v1.0 desktop (GUI, shell, filesystem, real-hardware boot).

5

Step 5

Join the community to get early milestones as they open up — Discord and the support portal are the channels.

6

Step 6

If you want to run a from-scratch OS today, experiment with hobby OS emulators — HeroOS will publish emulator images when milestones allow.

FAQ

Questions, answered

Is HeroOS a Minecraft mod?
No — it is a standalone operating system written in Rust, separate from the Minecraft software line.
Can I run it on my PC?
Not yet. It runs in an emulator today — Phase 1 boots to a framebuffer boot banner and kernel logs — and real-hardware support is a v1.0 goal.
Will it really replace Windows?
That is the long-term vision, reached milestone by milestone — an honest path, not a promise. Phase 1 is done; Phase 2 (input, timers, user mode) is next.
Can I download a build?
Not yet. There are no public builds until later milestones are reached; Phase 1 is a kernel milestone, not a downloadable OS.
What is actually working today?
Phase 1 complete: paging, heap, GDT/TSS, IDT and PIC/PIT in a memory-safe Rust no_std kernel with minimal x86-64 assembly — 10 self-tests passing, booting to a framebuffer boot banner and kernel logs in an emulator.
What comes after Phase 1?
Phase 2 — keyboard, mouse, RTC and user mode — then a driver framework with loadable kernel modules, and finally the v1.0 desktop (GUI, shell, filesystem, real-hardware boot).
How is it built?
A memory-safe Rust no_std kernel with minimal x86-64 assembly, booted via UEFI. Everything — kernel, drivers, GUI, shell, filesystem, package manager — is owned end to end.
How can I follow or contribute?
Follow the roadmap on this site, and join the Discord for early milestones. Privacy by design: no ads, no forced updates, no telemetry.
