The short version

  • Aiven is a fully managed cloud data platform.
  • Bubble is free; Aiven starts at $19/mo.
  • Only Aiven lists multi-cloud Support; only Bubble lists visual app editor.
  • Where Aiven falls short: the free plan gives 1 VM with 1 CPU, 1 GB RAM and 1 GB storage, and cannot pick a specific cloud or region.
  • Where Bubble falls short: apps are tied to Bubble's proprietary runtime, making migration to another stack difficult if the platform is later outgrown.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aiven

  • The free plan gives 1 VM with 1 CPU, 1 GB RAM and 1 GB storage, and cannot pick a specific cloud or region
  • Free and Developer tiers have no integrations and no connection pooling
  • Connection pooling, database forks and dynamic disk sizing need the Business or Premium plan
  • A 99.99 percent uptime SLA starts at the Startup plan from $75 a month
  • High availability with automatic failover starts at Business from $180 a month

Bubble

  • Apps are tied to Bubble's proprietary runtime, making migration to another stack difficult if the platform is later outgrown
  • Complex apps can hit performance limits compared to hand-coded applications as data and workflow complexity grows
  • The visual workflow editor has a steep learning curve for genuinely complex business logic
  • Free tier cannot host apps on a custom domain, limiting it to prototyping rather than production launches
