Haiku R1/Alpha 1 Ships as the Project's First Public Release
On September 14, 2009, eight years after OpenBeOS began, Haiku shipped its first version the public could actually download and boot — as a live CD, something BeOS itself never offered.
Haiku R1/Alpha 1 was released on September 14, 2009 — the project’s first version made available to the general public as a working, downloadable, bootable image, roughly eight years after the OpenBeOS project began in the wake of Be Inc.’s acquisition by Palm.
A live CD — a genuine improvement over the original
Alpha 1 could be booted and run directly from a CD without installation, letting anyone try the system without committing disk space or going through an install process first — notably, this was something the original BeOS itself never offered, making Alpha 1 in this one specific respect a practical improvement over the platform it was continuing rather than merely a replica of it.
Still explicitly an alpha
The “alpha” label was accurate, not just cautious naming — Haiku at this stage had known gaps and rough edges, and the release was explicitly framed as a demonstrably working, usable system rather than a finished, general-purpose replacement for a daily-driver OS. That framing mattered for setting expectations correctly: Alpha 1’s significance was proving the project had produced something real and usable after years of below-the-radar development, not that it had reached feature parity with BeOS or any contemporary mainstream OS.
What followed
Three more alpha releases shipped over the next several years — Alpha 2 in May 2010, Alpha 3 in June 2011, and Alpha 4 in November 2012 — each incrementally improving hardware support and stability, ahead of the considerably longer stretch of work that eventually led to Haiku’s first beta release in 2018.
Why a public alpha mattered for a volunteer-driven project
Shipping something the public could actually run, rather than continuing purely internal development indefinitely, gave the Haiku project a much wider pool of people who could test the system on real, varied hardware and report back — feedback a small, mostly-volunteer contributor base couldn’t generate on its own no matter how much internal testing it did. Alpha 1’s release is, in that sense, as much a milestone in how the project sustained itself long-term as it is a technical one.
