A free desktop OS reviving BeOS-style speed and simplicity.

Haiku is an open-source operating system for personal computers, built as a modern continuation of ideas from BeOS. The project site provides install downloads, user guides, release notes, nightly test images, development updates, and links into its community channels.

Why it stands out

  • A full independent desktop OS project, not just a Linux distribution or desktop theme.
  • Carries forward BeOS-inspired design goals with a clear focus on personal computing.
  • Publishes frequent development activity, contract reports, and release notes for project transparency.
  • Offers nightly images for users who want to test current development work.
  • Maintains visible community pathways through forums, IRC, mailing lists, and Google Summer of Code participation.

Good to know

  • The current public release line is still in beta rather than a final R1 release.
  • Nightly images are explicitly for testing and may be unstable.
  • Some packages included with official releases may need separate installation when using nightly builds.
  • The project is aimed at personal computing, not server, mobile, or enterprise deployment scenarios.
