Aiven vs Convex Pricing (2026)

Which one is cheaper?

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

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?

Different approach here. Aiven uses usage-based pricing, while Convex goes with hybrid. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Aiven: Aiven undercuts AWS RDS and GCP Cloud SQL at the entry point (free tier, $5 plans) to hook indie developers, but the Startup-to-Premium range ($75-$270+) puts them in line with — sometimes above — dedicated DBaaS competitors like Crunchy Data or Timescale Cloud. They're clearly playing multi-cloud flexibility as the wedge to win teams who don't want to be locked into a single hyperscaler's database service. Convex: Convex undercuts most backend-as-a-service and database platforms at the entry point — $25/seat is cheap for what's essentially a full reactive backend — but the $2,500/mo Enterprise floor signals they're not chasing bargain-hunting startups at scale. They're positioned to win indie devs and small teams early, then convert the ones that stick into higher-value accounts rather than nickel-and-diming growing teams seat by seat.
