Interactive phylogenetic tree and comparative intelligence engine mapping 816 operating systems across seven decades of computer science history (1950–Present).
OS-Graph models the complete genealogical lineages, structural bifurcations, and architectural mutations of operating systems from early mainframes to modern microkernels.
Spanning 816 curated individual systems and 696 directed evolutionary relationships, the platform reconstructs Unix, BSD, Linux distributions, Windows/DOS, macOS/Darwin, and independent academic research platforms. It calculates Lowest Common Ancestors (LCA) across disparate trees, analyzes instruction set architecture (ISA) overlaps, and aggregates multi-regional historical dossiers with zero external backend dependencies.

The operating system phylogenetic graph is synthesized from encyclopedic archives (Wikidata, Wikipedia), academic retrospectives, UNIX genealogy charts, and open distribution records spanning over seven decades of computer science history (1950–Present).
Due to the decentralized, multifaceted, and evolving nature of software engineering history:
- Historical Approximations: Inception years, kernel architectural classifications, and primary progenitor assignments represent established historiographical consensus. Individual academic or corporate sources may occasionally record divergent dates (e.g. project inception vs. initial public announcement vs. commercial availability).
- Multi-Parent & Hybrid Influences: Many modern operating systems synthesize components from disparate lineages (such as GNU userland tools, BSD network stacks, Mach microkernels, or hybrid abstraction layers). The primary displayed links model direct architectural or distribution parentage to preserve a legible phylogenetic tree.
- Reporting Inaccuracies & Community Corrections: If you encounter an imprecise date, a disputed classification, or an overlooked historical milestone, community corrections are warmly welcomed! Please open an issue or submit a pull request with authoritative historical citations on GitHub.
