Where each one falls short

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

Fabi

  • Fabi is an early-stage company with a small team, so the durability risk is real and there is no obvious migration path for Smartbooks if it stops trading
  • There is no meaningful governance layer: no data catalogue, no certified metric definitions and limited lineage, so it does not scale to an organisation that needs a single agreed number
  • The free and Builder tiers cap AI requests, and the daily cap on Starter is reached quickly during genuine exploratory work
  • Connector counts are limited by tier, so the Builder plan at 39 dollars connects to exactly one data source, which is rarely enough in practice
  • It overlaps heavily with what Snowflake, Databricks and Hex now ship natively, so a company already paying for one of those is buying a fourth notebook interface

Harness

  • Essentials and Enterprise pricing requires sales contact; no published rates
  • DevOps Essentials has no on-premises deployment option
  • Internal Developer Portal requires minimum 20 developer licenses
  • Pipeline execution history retention 6 months (Essentials) vs 25 months as add-on (Enterprise)
