Hello, I was looking for some information about the pricing and requests limit in MapKit, but I couldn't find anything in the documentation. Are there any limitations like in google maps?
If you are using MapKit for native app development, there is no cost beyond your Apple Developer Program membership. There are rate limits per device for some of the APIs, such as geocoding, but you'll only encounter them if you're sending off requests at more than the speed a normal user could reasonably use your app.
If you are doing web app development with MapKit JS, you get a daily limit of 250,000 map views and 25,000 service calls per Apple Developer Program membership. This is documented at the bottom of this page, as part of the MapKit JS Dashboard section.
