Choosing an Open-Source Map for E-commerce App with User-Defined Routes and Real-Time Traffic Data [closed]

Hello Stack Overflow community,

I am currently participating in a hackathon, and my project involves developing an e-commerce android app that addresses the challenge of high delivery costs for small buyers. To mitigate these costs, I am opting for an open-source approach, and I need your guidance on choosing the most suitable open-source map for my application.

I have narrowed down my options to Mapbox, Leaflet, and OpenStreetMap. However, I’m unsure which one would be the best fit for a unique feature I want to implement. The app aims to allow users to define the delivery route for drivers, providing a solution to the common problem of drivers receiving incorrect directions.

Here are my key considerations:

Map Options: Mapbox, Leaflet, OpenStreetMap – Which one would be most suitable for integrating user-defined routes effectively?

Real-Time Traffic Data: I also want to enhance the app by integrating real-time traffic data. Where can I access reliable real-time traffic data for this purpose?

I appreciate any insights or recommendations from your experiences. Thank you in advance!
