Features
Kernel and Architecture
- Long Mode Architecture — Native x86_64 implementation utilizing 64-bit address space and registers
- Symmetric Multi-Processing — Scalable multi-core support with IPI-based scheduling and synchronization
- Advanced Memory Management — Custom slab allocator with object pooling and efficient physical/virtual page mapping
- Hybrid VFS Layer — Unified filesystem interface supporting FAT32, TAR, ProcFS, and SysFS
- Preemptive Multitasking — Prioritized process scheduling with full context isolation
- Hardware Abstraction — Comprehensive driver support for PCI, AHCI, PS/2, and ACPI
Graphical Desktop Environment
- BoredWM — High-performance window manager featuring window stacking, focus management, and drag-and-drop interactions
- Typography Engine — Integrated font manager with TrueType (TTF) support and efficient glyph caching
- Rich Media Subsystem — Native hardware-independent decoding for PNG, JPEG, GIF, BMP, and TGA formats
- LibWidget Toolkit — Native UI component library for rapid application development
Networking Stack
- TCP/IP Integration — Full lwIP-based network stack featuring DHCP, DNS, and Berkeley-style sockets
- Network Services — Integrated support for basic web browsing and real-time network telemetry

☕ Support the Journey
If you find BoredOS interesting or useful, consider fueling development with a coffee!
History
BoredOS is the successor to BrewKernel, a project started in 2023. BrewKernel served as the foundational learning ground but has since been officially deprecated and archived — it no longer receives updates, bug fixes, or pull request reviews.
BoredOS is a complete architectural reboot, applying years of lessons learned to build a cleaner, more modular, and more capable system.
Important
Please direct all issues, discussions, and contributions to this repository. Legacy BrewKernel code is preserved for historical purposes only and is not compatible with BoredOS.
