Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
Protomaps – A free and open source map of the world

Worth mentioning this project (https://github.com/onthegomap/planetiler) that lets you create osm mbtiles and pmtiles pretty easy!12 projects | news.ycombinator.com | 23 Oct 2023
Radar Maps: $0.50 per 1K map loads

For a self-hosted vector tile stack you can have a look into https://github.com/onthegomap/planetiler I found it very easy to get started and when you know the other stacks it is also very fast to create these vector tiles even for planet-scale.
(note, that I'm not affiliated with them, but they use some source code from us for the efficient import and also contributed to GraphHopper, but this did not influence my experience ;) )
> I wonder why so many seem to be moving away from raster tiles to vector data.
The flexibility of styling. And you can easily serve customers that need different default languages. This makes maps also more accessible for countries without Latin alphabet.

SQLite performance tuning: concurrent reads, multiple GBs and 100k SELECTs/s
5 projects | news.ycombinator.com | 12 Apr 2023
I spent a while optimizing sqlite inserts for planetiler, this is what I came up with:
It batches inserts into bulk statements and is able to do writes in the 500k+ per second range, and reads are 300-400k/s using those settings.
How The Post is replacing Mapbox with open source solutions

Super easy way to generate a MBTiles, which you can then serve directly, or further convert to PMTiles, which can be used to host vector tiles for client-side rendering using MapLibre (or other renderers).
Raster tiles are a lot harder because you have to generate them on the server, and that's a lot more resource intensive.
Self-Hosted Vector Tiles
4 projects | news.ycombinator.com | 26 Jan 2023
I built planetiler (https://github.com/onthegomap/planetiler) for this purpose. The output up to z14 is ~80gb and depending on how big of a machine you have it takes from 30 minutes up to a few hours - no DB required, just java or docker. If you are only going to z11-12, it should be quite a bit faster/smaller.
Brandon from Protomaps is also helping add pmtiles output natively to planetiler, so you won't need a conversion step afterwards!4 projects | news.ycombinator.com | 26 Jan 2023
Does anyone know where to find the global raster set of buildings??

It's not raster directly, but you could use planetiler ( https://github.com/onthegomap/planetiler ) to build a full planet vector map . Then you could use something like TileServer-GL to server the vector map with a style. TileServer-gl ( https://github.com/maptiler/tileserver-gl) would provide a raster source that displays in the style you set on your vector map.
