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
Yarn
- Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
- Smaller ecosystem and community compared to npm, though still substantial

Answered from the vendors’ own pages
Fabi: Is there a free plan?
Yes, a Starter tier with one builder, ten viewers, five Smartbooks and ten AI requests a day.
Yarn: What is Yarn's main advantage over npm?
Yarn downloads packages in parallel, significantly reducing installation time. It uses a yarn.lock file for deterministic installs, ensuring identical package versions across machines and preventing version conflicts common with npm.
SourceFabi: Do viewers cost money?
Viewers are bundled by tier rather than charged individually; builders are the priced seat.
Yarn: Can I use Yarn in offline environments?
Yes, Yarn supports secure offline environments. The yarn.lock file enables reproducible installs without requiring new downloads.
SourceFabi: Can I run arbitrary Python?
Yes, Smartbooks include Python cells alongside SQL and no-code steps.
Fabi: How many data connectors does the entry paid plan include?
One. Additional and premium connectors come with the Team tier.
