SerenityOS is an open source Unix-like operating system project with its own custom kernel, graphical user interface, system libraries, and userland tools. It combines a nostalgic “90s UI aesthetic” with modern system capabilities: a preemptive, multi-threaded kernel, own browsers, network stack, file systems, IPC, security features, and a suite of graphical / developer applications. The project is both a hobbyist OS and a polished engineering sandbox.
Features
- Modern 64-bit kernel (with support initiatives for ARM / RISC-V) with preemptive multitasking
- Unix-like system services: window server, login server, audio server, web server, IPC, etc.
- POSIX compatibility: standard commands, shell, syscalls, signals, file paths, /proc, /dev, etc.
- Built-in browser (Ladybird) with support for JavaScript, WebAssembly, CSS, own engine (LibWeb / LibJS)
- Memory / security features: W^X memory policy, ASLR, OOM resistance, content isolation, “pledge” / “unveil”-style capabilities
- Rich standard libraries, development tools (IDE, debugger, profiling, editors), and support for graphics, audio, multiple file formats
