Neon vs MongoDB Atlas Pricing (2026)

Which one is cheaper?

One or both use custom pricing, so it depends on your specific needs.

Can I use either one for free?

Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.

How do they charge?

Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.

Which one is a better deal?

Depends on what you need. Neon: Neon positions itself as the developer-first alternative to RDS or traditional managed Postgres, betting that serverless scaling and instant branching justify a usage-based model over predictable flat pricing. It's not competing on being the cheapest — it's competing on infrastructure elegance for teams building on Postgres who are tired of provisioning fixed instances. MongoDB Atlas: MongoDB sits mid-to-premium in the database-as-a-service space — pricier than raw self-hosted Postgres or DynamoDB's pay-per-request model, but justified by the managed ops layer and document-model flexibility. They're clearly hunting teams who've outgrown free-tier NoSQL options and need something that won't fall over at scale.
