Become a sponsor to Chelsea Kelly-Reif

I'm Chelsea Kelly-Reif, an engineering leader in public-interest technology. In my own time I build open-source tools that make public data easier to trust and use:

  • GTFS Scorecard scores public transit feeds every day and publishes the results free for every agency.
  • FHIR Scorecard checks the public FHIR endpoints of payers, EHR vendors and health systems.
  • Validators for OSCAL, TODS and CTDL that catch problems before they ship.
  • Free web tools, such as a California trout-stocking schedule and plant-care guides.

What sponsorship pays for: hosting and bandwidth, the scheduled daily data refresh, and validator compute. These tools stay free for the people they score.

What it never buys: influence over grades, methodology, or which agencies are listed.

Thank you for reading, and for anything you choose to give.

Sponsorship never buys influence over findings, methodology, or which projects are covered. Being listed by name and link is available on request; anonymous is the default.

$25 a month

Past keeping the lights on and into doing more of the work: more frequent data refreshes, more validator compute, longer retention of the evidence that makes a published check reproducible.

Sponsorship never buys influence over findings, methodology, or which projects are covered. Being listed by name and link is available on request; anonymous is the default.

$100 a month

Select

Most of the way to the stated capacity envelope of 75 to 200 dollars a month, which is what it would take to widen coverage while keeping hard spending caps in place.
