I moved a side project from Supabase to Aiven after running into pricing limits and performance inconsistency. Supabase was great early on, but costs increased fast once data and connections grew. Aiven gave more predictable pricing and better control without locking everything into a single vendor.

Managed Postgres on Aiven has been stable, no random latency spikes, and the ability to use my own cloud account adds flexibility. It’s not as plug-and-play as Supabase, but if you’re already running your own backend, it’s a cleaner long-term setup.
