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.

Serverless maps at 1/700 the cost of Google Maps API
Hi, the value add in the commercial offering is described here:
https://protomaps.com/docs/faq#openstreetmap
I also maintain open source tooling for anyone to replicate and consume all of OSM, as well as a free download portal:

Why OSM doesn't use PostgreSQL for replication?
I work a lot with OSM data, and never loaded into PostgreSql… On one project I keep data in https://github.com/protomaps/OSMExpress, another I keep it in .pbf and just handle minutely changes in memory, then even for PostgreSql there are multiple schema tables each optimized for different work, render server schema is very different from API server…

Best practice for PBF filtering?
You did not specify what kind of filtering you want to do, but if you are after area extracts like whole cities or similar, best thing is OSMExpress unfortunatly it takes long time to initialize it for whole planet, but after that extracts are done in seconds.

Protomaps - a new way to make maps with Openstreetpap
The major open source component that runs on the server (https://github.com/protomaps/OSMExpress) is tricky to package because it depends on S2 Geometry, which itself has some tough dependencies; the users I know out there are compiling it themselves, or using the community-contributed Dockerfile. I would prefer a .deb, do you think a PPA is the right approach?

Is it possible to use C++ libs on Flutter desktop apps?
This is the library here: https://github.com/mapbox/mapbox-gl-native
-
Max zoom levels?
Yes, I'm using the Flutter MapBox GL project (that uses the native implementation, which is mostly written in C++). I'm using vector tiles, and it's getting down to 1.35cm/pixel for iOS and .12cm/pixel for Android at my latitude; I believe this is level 22 for iOS and 25.5 for Android.

Interactive maps in C++ applications
Mapbox has a c++ sdk as well as a GL renderer

Maps Offline?
But vector tiles is indeed the way to go, but it's also much more complicated. Everyone that has worked on Maps so far has done it either as a SoC / Outreachy student or on weekends and evenings. Look at https://github.com/mapbox/mapbox-gl-native if you want to get a feel for the complexity of a client side implementation of rendering vector tiles.
