  Flexible tool to build planet-scale vector tilesets from OpenStreetMap data fast

  

Looks like a nice offering. For those interested in an even more self-service style option -- check out https://github.com/onthegomap/planetiler. Spin up a high-memory spot instance on your favorite cloud provider, run a command, let it run a few hours, and now you've got a complete tileset for the planet at the cost of a couple of bucks. I'm not affiliated but I've been using it for my own project (http://www.lumathon.com/map) and I've been very happy.

  Pelias is a modular open-source geocoder using Elasticsearch.

  

The stack I describe in the post is only for map tiles - Map tiles are a good fit for CDNs because the input space is small (just Z/X/Y coordinates on a square grid) and thus very cacheable.

Geocoding is a very different problem because the input space - human language - is much, much larger, and answering queries quickly to support features like autocomplete really requires a server with hot data in memory.

One of my favorite projects in this space is Pelias https://pelias.io which is an open source auto-completing geocoder based on OSM plus other open data. It's backed by a great team that also runs a business: Geocode Earth https://geocode.earth

  Cloud-optimized + compressed single-file tile archives for vector and raster maps

  

* It is designed for remote HTTP range reads. If your application can instead directly access a filesytem, like on a mobile phone, MBTiles, which uses SQLite, is a more established solution.

The specification is open source on GitHub https://github.com/protomaps/PMTiles and is still evolving in response to user needs. I've created direct client support for Leaflet and MapLibre, and plan to work on OpenLayers next.
