Thanks for your interest!
Kailona is especially for the end users who would like to keep their health data with full control in a private single place from different platforms and healthcare providers. It provides the integration capabilities of any hospital systems on a well known standard in healthcare, HL7 FHIR®, so that is why it uses a FHIR® server as data store.
It is easy to setup an open source FHIR® server and configure it with Kailona if you are a Nextcloud Admin and familiar with its deployment. You can find the instructions here:
We will also launch our public live site with a centralized FHIR server for the end users who are not comfortable with such deployment / installation or who would like to register and use Kailona quickly. That site will be live soon here: https://app.kailona.org
Please stay tuned, and we appreciate your feedback!
