Amazon Aurora vs Nile
SEPT 2026 auditA comparison of Amazon Aurora and Nile built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
Choose Amazon Aurora if…
Teams on AWS who want a Postgres or MySQL cluster that can throw off a copy-on-write clone of production in minutes, keep up to fifteen readers behind it, and pause to nothing between bursts in serverless mode.

Choose Nile if…
Multi-tenant SaaS where every customer wants isolation — Nile makes a database per tenant the default shape rather than something you build on top of Postgres.

Consider something else if…
- Amazon Aurora: You want the upstream database rather than a compatible one, or a branch workflow rather than a clone. AWS documents cloning as a way to build a test environment, not as something you do per pull request.
- Nile: Several of the features on its own pricing table are marked Coming soon, including branching, backups and provisioned compute, so what is bought today is narrower than the table suggests.
2 sourced criteria separate them — see where, with sources, below.

At a glance.
| Criterion | Amazon Aurora | Nile |
|---|---|---|
| Pricing | ||
| Pricing model | Pay per use with no plan fee: instances plus storage plus I/O, or ACU-hours in serverless mode. AWS's own worked example prices serverless compute at $0.12 per ACU-hour on Aurora Standard and $0.156 on Aurora I/O-Optimized in US East (N. Virginia) — the difference being whether I/O is metered separately or folded into a higher compute and storage rate. Provisioned instances also offer Reserved Instance pricing, and usage may qualify for Database Savings Plans against a committed hourly spend. | Priced on queries rather than instances, with a $15 base for Pro. Nile's own framing is "Pay for queries, not for instances", and additional tokens are $0.05 per million. |
| Data | ||
| Engine | MySQL- and PostgreSQL-compatible. Aurora is AWS's own engine rather than a hosted build of either, so compatibility is the claim being made — existing code, tools and applications are stated to work, which is not the same as being the upstream database. | PostgreSQL, with tenant isolation as a first-class concept — databases, tenant databases and vector embeddings are all described as unlimited. |
