Haiku, the open-source successor to BeOS, celebrated its 25th anniversary in August 2026. Shortly after, the project released R1/beta6. Despite its long development cycle, the system remains a fully functional OS with its own kernel, graphical environment, and support for modern browsers like Firefox.
The project maintains compatibility with legacy BeOS applications on 32-bit systems by supporting older GCC 2 compilers alongside modern versions. The x86_64 version, however, does not run legacy binaries. Development is primarily driven by volunteers, with the non-profit Haiku, Inc. funding server costs and a single paid developer.
The beta6 update includes over 530 fixes and improvements. Key technical updates include a 5-10x speed increase in MIME-type detection and improved memory management, with packagefs structures requiring 20% less RAM. The system now supports hardware virtualization via NVMM for QEMU on x86_64 systems.
Haiku now features an official port of Firefox, alongside other browsers like LibreWolf and Waterfox for x86_64. While the system is not intended to compete directly with Windows or macOS, it aims to provide a cohesive desktop environment where the kernel and services are developed under a unified design philosophy.
Hardware support continues to evolve, with improvements for modern x86 machines and expanded USB Wi-Fi/Ethernet support via ported BSD drivers. Experimental work is underway for ARM64 and Apple M1, though these remain in the early stages. The developers explicitly stated that no generative AI code was used in the system components.
