Stratum
A curated library of free, public APIs. Stratum aggregates sources from governments, research labs and the open web, then exposes each one through an adaptive viewer that matches the shape of its data: JSON trees, tables, maps and charts.
Context
Discovering a good open API today means stitching together random lists, dead links and outdated docs. Stratum is a single place where every entry is verified, categorized and made browsable, with viewers that fit the data rather than a generic JSON dump.
Next.jsEngineering decisions
Next.js 16 with strict TypeScript, Tailwind v4 and Server Components by default. The registry of API sources is the single source of truth — every viewer reads from the same shape so the catalogue scales without bespoke pages.
