PMTiles

PMTiles is a single-file archive format for tiled data. A PMTiles archive can be hosted on a commodity storage platform such as S3, and enables low-cost, zero-maintenance map applications that are "serverless" - free of a custom tile backend or third party provider.

For those familiar with Cloud Optimized GeoTIFFs - PMTiles uses similar techniques, but is specific to Z/X/Y tiles and can store vector data.

Compatible Storage Providers

PMTiles files require servers to support HTTP byte serving as well as CORS. It's been tested with:
