Reflections on
Web Mapping.

Self-Hosted Vector Tiles with PMTiles and MapLibre GL JS

Serve a fully interactive web map from a single static file — no tile server, no backend, no infrastructure

Vector tiles have become the standard for interactive web mapping, but running a tile server has always been the barrier to entry. PMTiles changes this: it is a single-file archive format that lets browsers fetch individual tiles via HTTP range requests, turning any static host — S3, GitHub Pages, a CDN — into a tile server.
