Supabase

They should really add a way to send a query, it seems that we can only do the most basics things right now

did u figure out a way to send a query from the supabase client?

i know they have an sql editor which sends arbitrary queries to your host

but to make the call you need to have an encrypted connection string. so thats out of the question for doing client side queries
