It’s worth mentioning that portability is one of our core Principles at Supabase too:

This is why we don’t run a fork of Postgres, and we lean heavily into extensions rather than customizations. As the docs mention: this forces us compete on experience.

(Speaking here to your point about supabase, not to detract from Nile, which looks very cool)
