Exactly. I don't think Tesla would have anywhere near the sales they've had without Superchargers. The other EV manufacturers need to figure out how to offer something similar if they want any chance of competing.

Superchargers only work with Teslas due to some signaling and they aren't free for all Teslas. You can get an adapter that goes from a Tesla connector to J1772 but it won't work at a Supercharger, just home or destination chargers.

Tesla's aren't locked into using Tesla chargers. They do have a proprietary connector on the vehicles but they come with several adapters including J1772. Superchargers are a phenomenal perk, not a lock in.

I haven't put anything into production yet but I've been playing with PostGraphQL (https://github.com/postgraphql/postgraphql). It automatically creates a GraphQL endpoint based on your schema using Node. You define your application logic as functions in your schema. It also can handle authentication for you. I'd definitely recommend checking it out.
