Aurora OS Hero Light

​
Welcome to AURORA OS

A production-grade operating system with a hybrid kernel (monolithic core + modular services) that runs both natively on bare metal and in your browser via WebAssembly.

What Makes Aurora Special

Aurora runs everywhere:
  • Native: Boots on x86_64 and ARM hardware via UEFI/BIOS
  • Browser: Full OS experience via WebAssembly/WASI runtime
  • Same kernel, same apps, seamless experience
The browser runtime uses a BPE/U Engine (Browser Processing Engine/Unit) that emulates a complete virtual CPU.
Best of both worlds:
  • Monolithic core for performance (scheduler, memory, VFS)
  • Modular services for security and flexibility
  • Signed loadable modules for drivers
  • Capability-based IPC for process isolation
Hot paths stay in-kernel for speed, while drivers can be updated independently.
  • 4-level paging with higher-half kernel mapping
  • KASLR + ASLR for security
  • CFS-inspired preemptive scheduler
  • TCP/UDP/IP network stack
  • VFS with tmpfs, ext2, FAT support
  • Signal delivery with user-handler support
  • COW (Copy-on-Write) page fault handler
  • 60fps animations with GPU acceleration
  • Glass morphism and translucent surfaces
  • Material Design ripple effects on all interactions
  • Comprehensive keyboard shortcuts (press Shift + ?)
  • Persistent auth with OPFS + WebCrypto
  • Real boot sequence: BIOS POST → Bootloader → Kernel → Login

​
Design Philosophy

Performance First

Every animation runs at 60fps. Window open: 380ms. Button response: 120ms. Boot to desktop: < 2 seconds.

Security by Design

KASLR, ASLR, stack canaries, signed modules, capability-based IPC, and sandboxed agent execution.

Developer Friendly

Clean C/Assembly/Rust codebase. Comprehensive syscall API. Modular architecture. Full documentation.

​
Applications

Aurora includes a complete userland with modern applications:
  • Terminal — Full-featured shell with command history and xterm support
  • Files — Modern file manager with grid/list views and drag-drop
  • Browser — Web browser with tab support and real rendering
  • Text Editor — Code editor with syntax highlighting (CodeMirror)
  • System Monitor — Real-time CPU, memory, network metrics with charts
  • Settings — System configuration and preferences
