Unix Timeline

Research Unix, BSD, Linux, macOS, Solaris, and their branching relationships—preserved at full detail and extended through 2026.

From 1969 to 2026

Zoom and scroll to inspect the preserved drawing. Release labels are a snapshot of the drawing, not a live version feed.

Maintained geometry
 
The generator preserves the original detailed arrows and labels, extends active system bars and the time axis, and normalizes fonts for stable local rendering.

Refreshable versions
 
Release labels live separately from chart geometry. FreeBSD, NetBSD, OpenBSD, Darwin, macOS, GNU/Hurd, Minix, Linux, and Solaris can be refreshed without redrawing the lineage.
