Protomaps: Pricing, Features & Alternatives

Protomaps is the 'build it' answer in this category, and unusually it is a realistic one. Its PMTiles format puts an entire basemap into one archive you drop on S3, R2 or any static host; the client fetches byte ranges directly, so there is no tile server to run and no per-request meter at all. You trade the places database, geocoding and support for a hosting bill measured in single-digit dollars.
