The short version

  • Only MotherDuck has a free tier, so it costs nothing to try first.
  • Each has a real cost: MotherDuck the free Lite plan caps compute at 10 hours per month, which limits it to light or hobbyist workloads.; Rill Data the seat price of 20 dollars is misleading as a budget figure: Rill’s own calculator puts a small two-seat project at around 256 dollars a month, with compute making up the great majority.
  • They diverge on capability: MotherDuck covers Serverless DuckDB instances, Rill Data covers Local development.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

MotherDuck

  • The free Lite plan caps compute at 10 hours per month, which limits it to light or hobbyist workloads.
  • Business plan usage charges on top of the $250/month base can make costs less predictable than flat-rate competitors.
  • There are no academic or non-profit discounts, unlike some competing data platforms.
  • Annual billing requires going through a sales conversation rather than a self-serve toggle.

Rill Data

  • The seat price of 20 dollars is misleading as a budget figure: Rill’s own calculator puts a small two-seat project at around 256 dollars a month, with compute making up the great majority.
  • Dashboards are defined in YAML and SQL, so business users cannot create or change one without a developer and a Git workflow, which stalls self-service adoption.
  • It is built for the explore-a-metric pattern and does not produce pixel-perfect financial or operational reports, so most organisations still need a second reporting tool.
  • AI tokens and API calls are quota-limited per seat, with API overage at a cent per call, so programmatic consumers can create an unbudgeted line item.
  • As a smaller vendor competing against Looker, Tableau and Power BI, the ecosystem of consultants, templates and trained analysts is thin, which raises the cost of hiring for it.
