FHIR servers store and serve healthcare data organized as FHIR resources. The resources can be accessed programmatically via the FHIR RESTful API using the HTTP GET, POST, PUT, DELETE, etc. methods.
I've created this tool to simplify the interaction with a FHIR server by providing a simple UI for connecting to the server and browsing the FHIR resources. You can drill down into specific resource types, view individual resources, and navigate to the referenced resources by following the blue links.
