What should I use: Amazon RDS for PostgreSQL or Neon?

It depends on what you value most:

Choose Amazon RDS for PostgreSQL if you want:

• Full AWS integration: easiest choice if your app already lives in AWS
• More traditional database control: VPC networking, parameter groups, read replicas, backups, maintenance windows
• Predictable production setup: especially for steady traffic and established systems
• Enterprise/compliance needs: often preferred when you need tighter operational control

Choose Neon if you want:

• Serverless/Postgres with fast developer experience
• Branching and preview environments: great for testing, CI/CD, and per-feature databases
• Automatic scaling and low-ops: less database administration
• Cost efficiency for spiky or intermittent workloads
• Modern app workflows: especially for startups, prototypes, and developer-heavy teams

Quick rule of thumb

• If you’re building on AWS and want a managed, conventional PostgreSQL setup: RDS
• If you want serverless Postgres, branching, and better dev workflow: Neon

My practical recommendation

• Production, steady workload, AWS-native app → RDS
• Startup, greenfield app, lots of preview environments, variable traffic → Neon

If you tell me:

1. your cloud/provider setup,
2. expected traffic, and
3. whether you need branching/preview DBs,

I can give you a much more specific recommendation.
