Protomaps

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.

Protomaps publishes 1 API on the APIs.io network: Hosted Tile API. Tagged areas include Maps, Tiles, Geospatial, PMTiles, and Vector Tiles.

The Protomaps catalog on APIs.io includes 1 JSON-LD context.

Protomaps’ developer surface includes documentation, engineering blog, pricing, and 8 more developer resources.
