Aiven vs Supabase Pricing (2026)

Which one is cheaper?

Aiven starts lower at $5/mo, compared to $25/mo for Supabase.

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. Aiven: Aiven sits in the mid-to-premium range for managed open-source data services — they're not trying to undercut bare-metal DIY, they're competing with managed offerings from AWS, GCP, and Render by offering multi-cloud flexibility and a broader service catalog (Kafka, OpenSearch, etc.). The BYOC option signals they're actively courting enterprise buyers who can't send data to a third-party cloud. Supabase: Supabase is the scrappy, open-source alternative to Firebase — cheaper entry point, more transparent pricing, and no Google lock-in anxiety. They're targeting developers who want AWS-level infrastructure control without the AWS-level complexity or cost, competing directly with Firebase and PlanetScale in the mid-market.
