The sales-ready sandbox for healthcare

Your demo data says TEST CANCER. Sales has no place safe to show it live. Your customers hear "just trust us" instead of seeing the product. mock.health gives you thousands of synthetic patients with real clinical depth — ready now.

Coherent clinical data

Thousands of patient journeys with correlated conditions, medications, labs, imaging studies, and clinical notes. Clinical depth that survives a doctor's eyes — comorbidities that follow real patient patterns, not single-condition fixtures with no history.

US Core 6.1 out of the box

Validated US Core 6.1 profiles with full coding ontologies — LOINC, SNOMED, RxNorm, ICD-10. USCDI v3 data classes covered. SMART on FHIR authorization included, so you can test your app launch flows without waiting months for Epic sandbox access.

Patient portals included

EHR and payer portal clones bundled in. Your customers see what the real login experience looks like — not a blank FHIR endpoint. Test MyChart-style and UHC-style patient portal flows against realistic data.

API key in 60 seconds

A FHIR R4 compliant HAPI server underneath. No infrastructure to stand up, no test fixtures to maintain, no Synthea + HAPI + DevOps pipeline to babysit. Start querying patients before your next meeting.

Why mock.health beats rolling your own

Hand-rolled test data means broken references, missing imaging studies, radiology reports that read "FINDINGS: Normal. IMPRESSION: Normal.", lab values that are random numbers with no clinical correlation, and empty clinical notes. mock.health ships DICOM studies with modality-appropriate metadata, narrative radiology reports grounded in real clinical examples, lab panels with reference ranges and interpretation flags, discharge summaries that follow real documentation patterns, and a full OAuth2 + PKCE auth server ready for SMART on FHIR app launch testing.

Built on Synthea with a Markov progression module trained on 4.4 million real patient journeys. Conditions, encounters, medications, and procedures are data-driven rather than hand-authored — giving you the clinical diversity your demos need and your QA suite has been missing.
