[Disclaimer: I work for Xata]

As it happens, we've just launched our new Xata platform (https://xata.io/) which has some of the key Neon features: instant copy-on-write branching and separation of storage and compute. As an extra twist, we also can do anonymization (PII masking) between your production database and developer branches.

The way we do copy-on-write branches is a bit different. We haven't done any modifications to Postgres but do it completely at the storage layer, which is a distributed system in itself. This also brings some I/O performance opportunities.

While Xata has been around for a while, we're just launching this new platform, and it is in Private Beta. But we are happy to work with you if you are interested.

Btw, congrats to the Neon team!

I’ve had good experiences with Supabase.

If all you care about is the forking aspect we use DBLab Engine pretty effectively: https://postgres.ai/products/dblab_engine. Gets deployed within your own infrastructure.

Give Prisma Postgres a shot? https://prisma.io/postgres (I work for Prisma)

Supabase is your best bet.
