Where each one falls short

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

Budibase

  • Cloud plans are metered on automation actions, from 5,000 a month on Pro to 250,000 on Business
  • Creator seats are limited and cost $50 each beyond the included count
  • End users are $5 per user per month on top of the plan
  • Custom branding needs Premium, SSO enforcement and environment variables need Business, and audit logs are Enterprise only
  • Log retention is tiered from 1 day on Pro to 365 days on Enterprise

H2O.ai

  • Java is always required to run H2O-3 even when working from R or Python, and only a 64-bit JRE or JDK is supported
  • Supported Java versions stop at Java SE 17; newer versions only run by forcing an unsupported version flag and are guaranteed for experiments rather than production
  • H2O-3 only supports numpy below version 2, so a numpy 2 environment must be downgraded
  • Supported Python versions are limited to 3.7 through 3.11
  • The Flow web UI requires an internet browser and is the only graphical interface
