Where each one falls short

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

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

Swagger UI

  • Only as good as the specification: a thin OpenAPI file produces thin documentation
  • Default presentation is dated compared with modern documentation tools
  • Large specifications render slowly and become hard to navigate
  • Try it out against production needs care with authentication and CORS, and is often disabled as a result

Swagger UI: Is Swagger UI free?

Yes, open source under the Apache 2.0 licence. SmartBear sells commercial SwaggerHub separately.
