OSM is a dataset. That's free and open. There are different tile servers (https://wiki.openstreetmap.org/wiki/Tile_servers https://wiki.openstreetmap.org/wiki/Tile_servers) but they each have a different policy (https://operations.osmfoundation.org/policies/tiles/ https://operations.osmfoundation.org/policies/tiles/) In a nutshell: you can't just use them in production for your app. Development shouldn't be a problem. What you're talking about is precisely the commercial service that Mapbox offers. OSM (+ some extra stuff). Alternatively, you're free to spin up your own tile server. That way you don't pay anyone else (but you pay your server).
