# Aiven vs Nile

Canonical: https://inetgeek.com/compare/aiven-vs-nile/

Every value below is read from Aiven's and Nile's own documentation. See https://inetgeek.com/methodology/ for how.

## At a glance

| Criterion | Aiven | Nile |
| --- | --- | --- |
| Entry paid plan | $5 a month for Developer — one VM, 1 CPU, 1 GB RAM, 8 GB storage, with no choice of cloud or region and no connection pooling. The first plan that behaves like a production service is Startup at $75 a month or $0.10 an hour, which is where the uptime SLA and multi-CPU sizing begin; Hobbyist sits between them at $12. | $15/month for Pro, which carries a production SLA. Scale is $350/month. |
| Pricing model | Fixed plans quoted both monthly and hourly, with the plan setting CPU, RAM and storage together rather than metering them separately. Aiven describes the pricing as all-inclusive: backups, monitoring and support come with the plan instead of appearing as line items. Higher tiers buy node count and backup history — Business adds a standby node, Premium a second. | 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. |
| Managed connection pooling | Supported — not on the Free or Developer tiers | Supported |
| Engine | PostgreSQL, alongside MySQL, ClickHouse, OpenSearch, Valkey, Kafka, Flink and Grafana. Aiven runs the upstream projects rather than a compatible reimplementation, which is why its own docs point at postgresql.org for per-release detail. | PostgreSQL, with tenant isolation as a first-class concept — databases, tenant databases and vector embeddings are all described as unlimited. |
| Connection limit | Set per plan, not by a formula: 100 on the entry paid plan (Startup-4), rising to 200, 400, 800 and 1000 as the plan grows, with 25 on Hobbyist, 20 on Free and 15 on Developer. Aiven states plainly that it does not apply a per-GiB formula, and that some of the allowance is used by Aiven itself to manage the service. | 10,000 connections on Pro, with connection pooling included. |

## Where they differ

### Entry paid plan

- Aiven: $5 a month for Developer — one VM, 1 CPU, 1 GB RAM, 8 GB storage, with no choice of cloud or region and no connection pooling. The first plan that behaves like a production service is Startup at $75 a month or $0.10 an hour, which is where the uptime SLA and multi-CPU sizing begin; Hobbyist sits between them at $12. ([source](https://aiven.io/pricing))
- Nile: $15/month for Pro, which carries a production SLA. Scale is $350/month. ([source](https://www.thenile.dev/pricing))

### Pricing model

- Aiven: Fixed plans quoted both monthly and hourly, with the plan setting CPU, RAM and storage together rather than metering them separately. Aiven describes the pricing as all-inclusive: backups, monitoring and support come with the plan instead of appearing as line items. Higher tiers buy node count and backup history — Business adds a standby node, Premium a second. ([source](https://aiven.io/pricing))
- Nile: 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. ([source](https://www.thenile.dev/pricing))

### Engine

- Aiven: PostgreSQL, alongside MySQL, ClickHouse, OpenSearch, Valkey, Kafka, Flink and Grafana. Aiven runs the upstream projects rather than a compatible reimplementation, which is why its own docs point at postgresql.org for per-release detail. ([source](https://aiven.io/docs/products/postgresql))
- Nile: PostgreSQL, with tenant isolation as a first-class concept — databases, tenant databases and vector embeddings are all described as unlimited. ([source](https://www.thenile.dev/pricing))

### Connection limit

- Aiven: Set per plan, not by a formula: 100 on the entry paid plan (Startup-4), rising to 200, 400, 800 and 1000 as the plan grows, with 25 on Hobbyist, 20 on Free and 15 on Developer.

## Which should you choose?

Pick Aiven if Teams who want more than one open-source data service from one vendor and one bill — Postgres beside Kafka, ClickHouse or OpenSearch — with the availability tier chosen per service rather than fixed.

Pick 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: Aiven — You want long recovery history on a cheap plan. Backup history is what the plan tiers buy here: two days on the entry paid plan against thirty at the top.

Consider something else: 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.

## Documented by only one

- Free tier: Aiven: Yes — indefinite, but idle services are powered off
- Startup credit program: Aiven: Aiven for Startups: $12,000–$100,000 in Aiven credits over 12 months. Requires founded ≤7 years ago and external funding from pre-seed to Series B.
- Storage (entry plan): Nile: 5 GB on Pro, then $1.00 per additional GB.
- Regions: Aiven: 153 regions across six clouds — AWS 25, Google 42, Azure 39, OVH 22, UpCloud 16, DigitalOcean 9 — counted from Aiven's own reference list, which publishes the regions and no total. No magnitude is recorded, because Aiven states on that same page that the list differs per project and that not all service types are available in every cloud and region: the number is the platform's reach, not PostgreSQL's, and a bar drawn from it would be compared against providers whose counts are engine-specific.
- When idle: Nile: No cold start on Pro — Nile lists it as a plan feature rather than a behaviour to configure.
- Database branching: Aiven: Limited — a full copy from the latest backup, not copy-on-write
- Point-in-time recovery: Aiven: Bounded by the plan's backup history, so 2 days on the entry paid plan and 30 at the top. Granularity is fine within that: full backups daily with write-ahead logs copied every 5 minutes or per new file, whichever comes first.
- Read replicas: Aiven: Supported
- Backup retention: Aiven: By plan: none on Hobbyist, 2 days on Startup, 14 on Business, 30 on Premium. The magnitude is Startup's 2 days, the entry paid plan. Aiven's high-availability page states 2 days for Hobbyist where the backups page states none — the backups page is the more specific of the two and is what is recorded here.
