Hello Supabase team, Is there any way to show our domain in the API URL? Instead of the long URL of Supabase. Thank you!

At the moment, no

The only option that supports this would be to self-host the Supabase stack, and then point a DNS 'A' record towards it

For security reasons I had to implement a "Middleware" as the interceptor of this calls. In this case, my SSR of the project is the only one accessing the database. You can achieve this with nextJs, nuxtJs or sveltekit by only adding the supabase sdk in the server side api endpoints. But you will have to manage JWT by yourself. Edit: I am speaking in the case that you are referring to domains visible by the end users. Not dashboards or anything like that
