Aidbox FHIR Server

Aidbox is a FHIR-first platform combining an enterprise FHIR server and a purpose-built FHIR database in one system. Built on PostgreSQL with custom extensions, this FHIR server delivers:

• High-throughput ingestion (up to 20,000+ resources/second)
• Low-latency search across millions of FHIR records in a high-performance FHIR server
• Fast FHIR data export for analytics, migrations, or external system integrations
• Full control over indexing and data structure, letting you tailor performance optimizations and workflows to your exact needs

Unlike many solutions that abstract away the backend, Aidbox lets you access and manipulate your data directly — you can build custom business logic, implement advanced FHIR workflows, or tie into existing systems on your terms.

Health Samurai has implemented and supported dozens of high-load systems in production — spanning hospitals, labs, startups, healthcare software solution providers, and major payers — confirming the platform's performance and reliability.

1. FHIR-Native Database for a FHIR Server

Aidbox doesn't just provide a FHIR API; it includes a FHIR-optimized database built on PostgreSQL with custom extensions. By combining the API and database in one FHIR server platform, Aidbox ensures low latency, fewer moving parts, and less overhead than multi-service architectures.

2. High-Performance FHIR Data Processing

Aidbox easily handles thousands of operations per second, even when working with millions of FHIR resources. This includes fast reads and writes, so you can load patient data, run analytics, or power clinical apps without delay.

3. Flexible FHIR Server Infrastructure

Because Aidbox FHIR server is distributed as a lightweight Docker container that only needs PostgreSQL, this FHIR server avoids the hassle of complex multi-service setups. It's deployable on-premises, in the cloud, or in hybrid environments while reducing maintenance and potential points of failure.

4. Customizable Indexing for FHIR Data

Aidbox's PostgreSQL foundation means you can define your own indexing strategies, modify FHIR search behavior, and shape the data model to match your specific project needs instead of working around a one-size-fits-all approach.

1. High-volume FHIR data ingestion

We tested Aidbox FHIR server with 23 million and then 100 million resources via the /fhir/$import endpoint.

• Single FHIR Import (23M Resources): ~4.3 GB zipped (~17.9 GB unzipped), completed in ~65 minutes, ~6,000 resources/second
• Concurrent FHIR Import (100M Resources): 4 concurrent requests, 10 parallel workers each, ~180 GB in the database post-import, ~20,000+ resources/second peak throughput

2. Fast bulk FHIR export

When exporting 100 million FHIR resources via /fhir/$export: 202.8 GB of data, 1 hour 47 minutes total time, 15,500 resources/second (32.3 MB/s).

3. High-concurrency FHIR CRUD operations

Even under 300 parallel threads, Aidbox FHIR server achieves: Create up to 2,800 RPS (Observations), Read up to 3,500 RPS (Patients), Update ~1,900 RPS (Encounters), Delete over 3,900 RPS (ExplanationOfBenefit).

4. Optimized FHIR search with indexing at scale

FHIR search performance was validated across resources like Patient, Encounter, Claim, and Observation, with up to 5 million records: Patient Search ~2,081 RPS, Encounter Search ~3,125 RPS, Observation Search ~2,042 RPS.

Aidbox FHIR server offers speed, control, and reliability in one streamlined package. The result is a FHIR server platform that can scale from tens of millions to billions of FHIR resources, delivering:

Outstanding FHIR server performance on minimal hardware — Even an 8 vCPU, 8 GB RAM setup can yield results 10x faster than popular open-source FHIR servers.

Streamlined FHIR server operations — Aidbox's containerized distribution requires only PostgreSQL, minimizing deployment and maintenance.

Reliability under heavy FHIR load — High concurrency and large transaction bundles don't hamper Aidbox's responsiveness or stability.

Scalable Bulk FHIR Import & Export — Process large FHIR datasets—from millions to billions—end-to-end, quickly and without added complexity.

If you're looking for a powerful FHIR server platform that simplifies infrastructure, accelerates performance, and keeps data fully accessible, Aidbox is ready to meet your needs.
