Protomaps is an open-source map system that delivers an interactive map of the world as a single PMTiles file hosted on cloud storage. It provides a hosted vector tile API powered by Cloudflare CDN, plus tools for converting, serving, and delivering map tiles without servers using HTTP range requests. The PMTiles format enables self-hosting on S3, Cloudflare R2, Azure Blob, and Google Cloud Storage at a fraction of the cost of commercial map APIs.
