About

A ledger, not a library.

In 1983 Apple gathered its developers at the Dunfey Hotel in San Mateo — the conference that became WWDC. This site keeps the modern record: every session Apple still publishes, indexed by category, duration, the code shown on screen, and how each session links to the others.

Everything links to the source. Videos, transcripts, sample code and documentation live at developer.apple.com; this site stores metadata and aggregates only, for research and education, non-commercially.

Counted honestly. Apple revises its catalog over time — sessions are removed, labs are pruned, history shifts. Counts here come from snapshot 4351 of Apple's public feed (updated 2026-06-10), and years before 2019 reflect what remains published, not the full conference that took place.

Built as an open dataset and static site. The pipeline and source are on GitHub; the data is fetched from Apple's CDN at build time and never committed.
