Can anyone comment on PlanetScale vs Supabase? I'm not their target, because I'm just a random individual that wants a free database for personal projects. I could try both but would be nice to hear about someone's experience.
From my understanding Supabase is more of "all-in-one backend" whereas PlanetScale is "just" a DB (MySQL vs the Postgres it looks like you get on Supabase). PlanetScale also has some pretty awesome tools for moving DB schema changes between environments (zero downtime) and I don't know what Supabase provides for something like this. If all you want is a DB then give PS a try, I'm loving it so far, if you want a full backend "no code/low code"-firebase-like thing then Supabase might be for you. Personally I don't like going "all in" on something as important as "my whole backend", I'm much happier just getting a DB from PS and then using AWS Lambda as my "backend".
This is true, we do offer some extra functionality - but also I want to point out that the database we provide is "just" Postgres. You can use it as a standalone database without any of the other functionality. We give "postgres level access", so you can use it just like RDS or any other DBaaS
for example, we commonly see Prisma developers using our databases (because we also provide pgbouncer, a connection pooler).
