COVID-19 Resources

Helping people navigate the confusing healthcare landscape is the reason Castlight was founded. As we come together to tackle the challenges of life in a global pandemic, we’re more committed than ever to keeping you and your people safe, healthy, and informed.

Find COVID-19 vaccines

We’ve partnered with the Centers for Disease Control and Prevention and Boston Children’s Hospital to power, a free resource for Americans to locate COVID-19 vaccines. The Castlight team built the technology infrastructure to support up-to-date information on vaccine inventory, provider locations, hours, scheduling links, and more. Today, VaccineFinder powers, the federal government’s official resource for the public to locate vaccines.


Supporting public access to testing

At the onset of the pandemic in early 2020, we developed the first comprehensive nationwide COVID-19 Test Site Finder. The free, public directory feeds Apple and Google Maps searches for local testing resources and has been employed by state governments, Fortune 500 companies, and health plans.
