What Hacker News says

In Ask HN: What are some alternatives to Google maps?
It's different software. openstreetmap.org uses Nominatim: https://github.com/openstreetmap/Nominatim The photon link uses Photon: https://github.com/komoot/photon Nominatim processes OSM data, associating items of interest with features like town boundaries that enclose the item, or place markers that are nearby, and then is also a fairly pedantic search interface for that data. Photon takes the data that Nominatim generates and sticks a more flexible search on top of it. Checking for/creating an issue for Nominatim describing the address format that doesn't work well would be a useful thing to do, as global support is a goal there.
In How Facebook, Apple and Microsoft Are Contributing to OpenStreetMap
> I assume I'd be using at least a day to set things up You assume wrong. :) It takes an hour or so to get a tileserver up and running with the switch2osm instructions. I've done it countless times. (You do then need to wait for the Postgres database to populate, but that's just fire-and-forget.) They're written for Ubuntu LTS versions so the "newer versions" issue doesn't arise. Or if Docker's your bag, you can get a ready-to-go image from openmaptiles: https://openmaptiles.com/server/ > where anyone can spin it up for $5/mo Not gonna happen. Running a worldwide map server needs a lot of (SSD) storage and decent CPU. I have a £10/month Hetzner VM just to do geocoding (with Photon: https://github.com/komoot/photon) so you aren't going to get a tileserver for half that - and that's no surprise; OSM is ultimately competing with Google, and

you can't really expect to host your own Google for $5. But there are plenty of hosted options with tiered pricing.
In Why Use OpenStreetMap Instead of Google Maps?
There's (justifiably) a lot of love for Mapbox in this thread as an alternative, but as remarked, their pricing isn't particularly cheap (why should it be, they sell on the quality of the product). So the other option is to self-host tools using OpenStreetMap data. Some pointers: * Raster tiled maps: the canonical instructions are at switch2osm.org; put it on commodity hardware such as Hetzner/OVH. * Vector maps: a lot of development in this area at the moment and you could happily lose yourself for days among all the emerging solutions, but probably the easiest out-of-the-box solution is openmaptiles.org. * Geocoding: Photon (https://github.com/komoot/photon) is the easiest to set up because it comes with precompiled indexes - no need to generate your own. Based on ElasticSearch, needs SSD for reasonable performance. * Routing: OSRM (Map

box's routing engine) and Graphhopper are both self-hostable. OSRM is very RAM-hungry, but blazingly fast. This is just a start - there are many more options available, not least the whole stack developed by Mapzen before they shut down. The raw OSM data is downloadable from planet.openstreetmap.org (full dump) or http://download.geofabrik.de/ (regional extracts). Worth noting as well that there are a few well-established and competitively priced indie providers based on OSM: Thunderforest (http://thunderforest.com/), Geofabrik (http://geofabrik.de/), Graphhopper (https://www.graphhopper.com/).
