SerenityOS is a graphical Unix-like operating system for 64-bit x86, Arm, and RISC-V computers, built from scratch in C++ with a custom kernel, desktop environment, and applications. It combines a late-1990s productivity software aesthetic with modern power-user features including its own web browser, security hardening, and POSIX compatibility.
Use cases
- learn how an operating system kernel works
- run a self-contained desktop OS with its own web browser
- study a from-scratch C++ operating system codebase
- experiment with a POSIX-compatible hobby OS in a VM
- explore OS security features like W^X and pledge/unveil
- develop software with the bundled HackStudio IDE
When to choose
- you want to read or contribute to a complete, real operating system codebase
- you need a self-contained graphical Unix-like system for learning or experimentation
- you're interested in OS-level security research or kernel development
- you want a nostalgic desktop environment with modern internals
When to avoid
- you need a production OS for daily work or servers
- you require broad hardware driver support or mainstream software compatibility
- you need long-term support, enterprise tooling, or package ecosystems
- you want a lightweight Linux distribution rather than a full custom OS
