Vercel does come with a Supabase integration: https://vercel.com/integrations/supabase

And from my limited understanding, Supabase is psql with extras.

Supabase developer here. Supabase gives you full PostgreSQL access as well as a REST api interface (Postgrest) with integrated authentication (based on GoTrue), S3-based storage also integrated to authentication and integrated with your PostgreSQL instance, an easy dashboard interface and a bunch more. There’s a generous free tier and a hosted option that’s ready to scale immediately. Let us know if you have any more questions.

You guys should advertise the Postgres+Postgrest thing more prominently, I've been looking through your materials this morning and the Postgrest part wasn't clear. I would have been more apt to choose Supabase immediately since it seems like I wouldn't encounter vendor lock in, which was the main concern.

It's considered our "API", which is part of the "Firebase Alternative" marketing idea, but your point is duly noted and I'll pass it on to our devrel guys. Thanks.

I tried supabase and went with another solution because it didn't have a good dev/stage/prod system

Supabase developer here. We’d love your input on what you’d like to see for dev / staging / production. Please let us know what you’re looking for or the model you’re interested in.

I keep going back to your page. Very interested but lack the time and energy to build anything right now.
