About Strata

Strata is a fast, SEO-friendly dashboard of live data heatmaps. Each heatmap is a reusable component fed by a public data source through a cached serverless backend, so pages load quickly and the underlying APIs are never overloaded or exposed.

The site is built with Astro and React, styled with Tailwind CSS, and deployed on Cloudflare Pages. Pages are server-rendered so search engines see real content — not a loading spinner.

• Air Quality (AQI) Heatmap: Open-Meteo Air Quality API
