I use Aurora Postgres at work, where we pay approximately 9x more for equivalent resources to PlanetScale (according to their pricing page [1]). This is not an endorsement of PlanetScale as I've never used it, just pointing out that the premium for using Aurora Postgres is many multiples higher than virtually every other Postgres provider.

Please reach out to us we would love to talk to you about testing PlanetScale and seeing if we can drive your costs down and performance up.

I haven't used PlanetScale before, but AWS Aurora limits IOPS and network performance based on your instance size, so you end up in scenarios where you really wish you had more throughput, but sizing up your instance would be a very, very expensive solution
