In Development Platform

HeroOS

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

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.

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

Everything HeroOS does

5 features across 4 categories — all real, all working.

Custom Kernel

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

Boots today

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

Own GUI

Everything owned

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

Privacy by Design

No ads or telemetry

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

FAQ

Questions, answered

Is HeroOS a Minecraft mod?

No — it is a standalone operating system written in Rust.

Can I run it on my PC?

Not yet. It runs in an emulator today; real-hardware support is a v1.0 goal.

Will it really replace Windows?

That is the long-term vision — an honest, milestone-by-milestone path.

Can I download a build?

Not yet. There are no public builds until later milestones are reached.
