HL7 FHIR® Based Secure Health Data Repository
onFHIR.io is a scalable, high performance, secure FHIR server to manage HL7 FHIR® compliant healthcare data within health ecosystems.
Key Features
Comprehensive, version-agnostic, and customizable FHIR support
onFHIR.io implements the full range of FHIR capabilities—regardless of which version you choose—so you can adopt new releases or stick with legacy profiles without missing a beat. You can easily customize server behavior and discoverability using native FHIR constructs like CapabilityStatement and SearchParameter, ensuring your implementation matches exactly what your workflows demand.
Scalable, high-performance architecture
Built on MongoDB with configurable sharding and indexing, onFHIR.io effortlessly scales for massive datasets from small clinics to national repositories—supporting billions of Observation and other resources at a few millisecond response times.
Blazing-fast validation engine
onFHIR.io validates resources in real time against all types of FHIR constraints given in base standard, profiles or capability statement while maintaining compliance and data integrity—without sacrificing performance.
Fine grained security & auditing
onFHIR.io supports OpenID Connect and SMART on FHIR for authentication, plus RBAC/ABAC policy engines for precise access control. It provides configurable audit trail mechanisms to meet regulatory requirements (HIPAA, GDPR, etc.).
Developer-friendly extensibility
onFHIR.io allows you to extend core functionality with custom FHIR operations, integrate bespoke authorization or auditing logic with our Java/Scala SDK, and embed higher-level business logic directly into your FHIR resource management layer.
Flexible deployment models
onFHIR.io supports deployment on-premises or in your choice of AWS, Google Cloud, or Azure. Complementary load-balancing and monitoring toolkits help you achieve 24 × 7 uptime and operational visibility.
Mustafa Yuksel
Technical Project Lead
When we launched the HYP programme in Türkiye to standardize chronic disease care for 80 million citizens, we needed a FHIR server that could scale with our ambitions. onFhir.io wasn't just a backend—it became the backbone of our nationwide preventive care and chronic disease monitoring ecosystem.
With 38 billion FHIR resources and 220 million daily interactions, its MongoDB sharding and patient-centric indexing let us maintain a few millisecond response times, even during peak patient follow-ups. The ability to enforce fine-grained ABAC policies ensured 35,000+ practitioners only accessed data for their assigned patients, aligning with strict national privacy laws.
Use Cases
Explore how other initiatives/organizations use onFHIR.io.
National Health Data Repository
onFHIR.io serves as the secure backbone of HYP - Türkiye's national chronic disease management platform operational since 2020. This mission-critical system:
- digitalizes clinical guidelines for chronic disease screening, risk assessment, and personalized care planning,
- supports all registered family practitioners nationwide in performing standardized screenings and monitoring,
- integrates with Türkiye's national PHR system (eNabiz), unifying hospital/clinic records,
- grows continuously as the foundation of Türkiye's preventive care ecosystem.
onFHIR.io's sharding, indexing and high-speed validation ensure compliance and sub-second performance even under this national-scale load.

Integrated Care
C3-CLOUD is a European Commission sponsored project that develops an integrated care platform for the management of multi morbidity and polypharmacy.
onFHIR.io is used as the data platform of the C3-CLOUD ecosystem in the clinical studies realized in 3 pilot sites for the validation of the solution. It provides data interoperability among C3-CLOUD applications and existing EHR systems and clinical event/alert management based on FHIR subscription mechanism.
Clinical Decision Support
POWER2DM is a European Commission sponsored project that develops a personalized diabetes management platform consisting of mobile and web applications for patients and practitioners for shared decision making and care management with the support of a range of prediction and risk assessment tools. The solution is validated through a clinical study in two pilot sites in the Netherlands and Spain.
onFHIR.io is used as the data platform in POWER2DM solution and provides data interoperability among applications and decisions support services.
Patient Empowerment
CAREPATH is a Horizon 2020's project that proposes an ICT based solution for the optimization of clinical practice in the treatment and management of multimorbid patients with Mild Cognitive Impairment or Mild Dementia.
onFHIR.io is used as the data platform of the solution which manages health records of patients integrated from external systems and collected via the solution itself. The solution is validated in the clinical study realized in four different pilot sites in Germany, UK, Spain and Romania.
Clinical Research
AICCELERATE is a European Commission sponsored project that develops a set of tools for hospitals to leverage the data in Hospitals for realizing AI based solutions. The solution is validated in 5 hospitals across Europe in 3 different clinical studies.
onFHIR.io is used as a part of data integration suite for all pilot sites to store the transformed EHR data in a FHIR based common data model where AI ready datasets are extracted with further ETLs.
As a Test FHIR Server
HL7 Europe used onFHIR.io as dedicated public FHIR test server for their affiliates and members between 2021 – 2022.
Tuncay Namli
Principal Solutions Architect
What truly sets onFhir.io apart is its configurability. We tailored FHIR profiles to unify data from hospitals (via eNabiz) and community clinics, while SMART on FHIR integration streamlined practitioner workflows. When new chronic disease guidelines emerged, we updated StructureDefinitions and CapabilityStatements in hours—not months.
For any organization building a high-trust, high-scale FHIR platform: this is the solution that turns regulatory challenges into clinical impact.
