Browser API Atlas

An interactive graph-based explorer for every web platform API — the canonical surface of the modern browser, mapped, colored by your browser’s actual support status, and paired with live demos.

This site is a single-page application and needs JavaScript to render its graph, run feature detection, and execute the per-API demos. Please enable JavaScript or browse the source data instead:

MDN browser-compat-data — the canonical browser support data
web-features — the Baseline status data
web.dev/baseline — what “Baseline” classifications mean

A machine-readable sitemap is available at /sitemap.xml listing every API page.
