Aiven vs Turso
SEPT 2026 auditA comparison of Aiven and Turso built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
Choose 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.
Editorial · Palash Bagchi · approved
Choose Turso if…
Applications that want a database per tenant or per user — 100 databases on the free plan and unlimited above it make that a shape you can actually build.

Consider something else if…
- 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.
- Turso: It is SQLite, not Postgres: the metered units are rows read and written rather than compute, and the extension ecosystem you may be relying on is not there.

At a glance.
| Criterion | Aiven | Turso |
|---|---|---|
| Pricing | ||
| Free tier | Yes — indefinite, but idle services are powered off | Yes |
| 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. | $4.99/month for Developer, the cheapest paid plan. Scaler is $24.92 and Pro $416.58. |
| 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. | Per database, metered on rows rather than compute time: 500 million rows read and 10 million written a month on the free plan, 2.5 billion and 25 million on Developer, with overage at $1 per billion rows read and $1 per million written. |
| Data | ||
| 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. | SQLite, via libSQL — Turso's own fork. Not Postgres or MySQL, so the query surface and the client libraries differ from every other database on this site. |
| Database branching | Limited — a full copy from the latest backup, not copy-on-write | Supported |
| 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. | 10 days on Developer. 1 day on the free plan, 30 days on Scaler and 90 days on Pro. |
