A custom Epic FHIR integration costs your team 4–9 months and $150K–$300K. Epic CLI is $199/yr and works in 5 minutes. Here's the full breakdown.
These aren't worst-case numbers. They're what teams actually spend.
Every week your integration isn't live is a week you can't ship.
| Milestone | Custom Build | Epic CLI |
|---|---|---|
| First FHIR query running | 4–8 weeks | 5 minutes |
| Epic sandbox approval | 2–6 weeks (review queue) | Included — pre-approved |
| SMART on FHIR OAuth wired | 2–4 weeks | Built in |
| Production-ready | 4–9 months | Same day |
| First patient data retrieved | 3–6 months | Under 1 hour |
| Team onboarding | Weeks of documentation | npm install, 1 command |
Custom builds give you full control — of every bug, upgrade, and Epic API change.
Real questions we hear from engineering teams.
Epic CLI is API-first and TypeScript-native. You call it from your own code, control the data flow, and own the business logic. You're not locked into a black box — you're replacing the boilerplate plumbing, not the architecture.
Epic CLI runs in your own environment, on your infrastructure. No data leaves your stack. It's a library and CLI — not a cloud service with access to your patient data. SOC 2 documentation available on request.
You do. The question is whether you want them spending 4–6 months on FHIR plumbing or on your actual product. Epic CLI handles the OAuth handshakes, rate limiting, FHIR resource parsing, and Epic-specific quirks so your team doesn't have to.
That's exactly why you don't want to own this. When Epic updates, we update Epic CLI. Your integration keeps working. If you built it yourself, your team owns every breaking change.
