- Can I migrate from Neon?
- Yes. Start with the workflows or data you actually use, then cut over. The CloudNativePG / PostgreSQL stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Neon links until they expire.
- How do I deploy it?
- Open the CloudNativePG / PostgreSQL stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: PostgreSQL as a Railway database, or CloudNativePG on a cluster you already run. Bind the app to the private Postgres URL. No one-click CloudNativePG template in this repo yet — Start on Railway. Hosted SKUs stay on /compare/managed-postgres.
