# Aiven vs Crunchy Bridge

Canonical: https://inetgeek.com/compare/aiven-vs-crunchy-bridge/

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

## At a glance

| Criterion | Aiven | Crunchy Bridge |
| --- | --- | --- |
| 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. | $9 a month for Hobby-0 — 2 cores, 512 MB, AWS only. Crunchy says the Hobby tier runs on lower-quality infrastructure, has no PgBouncer and is not intended for production; the first production tier is Standard-4 at $70 a month for 1 core and 4 GB. There is no free plan. |
| 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. | Billed for the time a cluster is provisioned, prorated to the second, with the monthly figures on the plans page being what a full month costs. Price varies by instance size, region and storage. Three tiers — Hobby, Standard and Memory-optimized — where the tier decides IOPS, whether PgBouncer is included and what support you get, not just the size. |
| Managed connection pooling | Supported — not on the Free or Developer tiers | Supported |
| Regions | 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. | 37 regions across three clouds — 16 on AWS, 14 on Google Cloud, 7 on Azure — counted from the region tables on Crunchy's own plans page, which lists them and publishes no total. |
| 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 only. Crunchy Bridge is a single-engine service — there is no MySQL or analytics product beside it in the same offering — and it runs on all three major clouds so the database can sit next to whatever else you already run. |
| Database branching | Limited — a full copy from the latest backup, not copy-on-write | Limited — a new cluster restored from backup, to any minute in 10 days |
| Point-in-time recovery | 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. | Any minute inside the 10 days of retained backups. The WAL is streamed every 60 seconds or 16 MB, whichever comes first, and a restore produces a fork of the cluster rather than replacing it. |
| Read replicas | Supported | Supported |
| Backup retention | 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. | 10 days, included in the cluster price rather than sold as a tier, and extendable by configuring additional daily, weekly, monthly and yearly backups to keep. |

### 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. ([source](https://aiven.io/docs/products/postgresql/concepts/pg-backups))

## 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 Crunchy Bridge if Anyone who wants Postgres and nothing else, from people who work on Postgres. Ten days of per-minute recovery is included in the price of every cluster rather than sold as a tier, and replicas can sit in another region or another cloud.

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: Crunchy Bridge — You need a free plan to start on, or a second database engine later. This is a single-engine paid service.

## Documented by only one

- Free tier: Aiven: Yes — indefinite, but idle services are powered off
- 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. 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.
