Open Epic Is Opening for Real: Why This Matters for Innovators in Healthcare IT

A couple of months ago, I attended the Open@Epic Conference 2025 in Madison—the inaugural event, first of its kind, where Epic brought developers, startups, healthcare vendors, and health-system CIOs under one roof to talk about interoperability, standards, and third-party innovation.

For those of us who have lived through the “Epic is a closed ecosystem” narrative for years, this conference felt different. Not because everything is suddenly open—far from it—but because Epic is now visibly moving in the right direction, with concrete tools, APIs, sandboxes, and processes that signal a more collaborative future.

And now, with the refreshed open.epic.com site, this direction is even clearer.

This blog is my take on what has genuinely changed, what it means for startups and established firms, and why I believe we’re entering a new era of vendor collaboration—one that is long overdue in U.S. healthcare.

A Shift in Posture: From Gatekeeper to Platform Enabler
Historically, Epic has been accused—fairly or unfairly—of information blocking. Even when Epic insisted otherwise, the day-to-day experience for vendors often felt tightly controlled, slow, and opaque.

But at Open@Epic 2025, there was an unmistakable acknowledgement: the market expects—and demands—more openness.

Epic’s response? A series of initiatives that lower barriers for developers, increase transparency, and introduce clearer paths to integration.

From my notes at the conference:

Epic now handles ~2 billion API calls per day, signaling real-scale adoption by external tools.
Hundreds of APIs are published openly, with more available through structured partner programs.
New sandbox environments and playbooks aim to accelerate app development and help vendors navigate compliance, security, and implementation.

This is not just a website refresh. It’s a strategic repositioning—from EHR monolith to a healthcare technology platform.

What’s New on open.epic.com—and Why It Matters
Epic has reorganized its developer ecosystem into a cleaner, more navigable structure. Several elements stood out to me:

1. Clearer API Catalogs
   The site now showcases:

Public FHIR APIs
Private, customer-enabled APIs
Specialty workflows such as patient identity, scheduling, and clinical data access

This is valuable for two audiences:

Startups: Faster experimentation, clearer expectations, transparent pathways to go live.

Established vendors: Better planning for integration roadmaps; ability to assess what’s native, what’s premium, and where collaboration is required.

Epic still maintains a paywall for certain APIs—vendors at the conference did grumble about how the cost of these APIs can add up quickly—but the transparency is significantly improved.

2. A Step-by-Step Integration Path (“Showroom Path”)
   A major improvement is the documented journey from idea → app → test → listing. This demystifies the approval process and sets expectations for both startups and enterprise vendors.

The addition of Data Sharing Playbook in the website is a great asset to developers. And the App Journey has now been clearly laid out from open.epic.com to -> Showroom to -> Connection hub to -> Technology Guidance Forum to -> Vendor services to -> Toolbox.

3. OAuth2 Guidance and Security Best Practices
   Epic’s updated guidance helps developers avoid common pitfalls in healthcare authorization flows—an evergreen pain point.
4. TEFCA, FHIR Roadmap & Regulatory Alignment
   Epic’s TEFCA sessions and the expanded FHIR roadmap matter because:

The industry is shifting toward standards-based exchange
Vendors want predictability
Health systems increasingly expect TEFCA-compliant capabilities

This alignment reduces friction when introducing new data-driven apps into Epic environments.

5. Tools for Patient-Centered Innovation
   Epic highlighted tools that allow:

Remote patient monitoring integrations
Bluetooth device connections
Patient-driven care plan workflows

This is a strong signal that the “patient app” ecosystem around Epic is about to expand meaningfully.

What I Learned from the Provider (CIO) Panel
The CIOs from Mass General Brigham, Mayo, OHSU, and Vanderbilt made one overriding point:

If your app is going to last inside a major health system, it must be safe, secure, reliable, and designed for clinical workflows—not just for demos. —Provider Panel, Open@Epic Conference
For vendors, the message is clear: Innovation is welcome, but trustworthiness is non-negotiable.

AI: Present, but Quietly
AI wasn’t the dominant theme of the conference—surprising, given the industry buzz. But the signals were there:

Epic openly discussed its challenges deploying AI safely at scale.
They referenced the open-sourced patient summarization model developed with Yale—an important benchmark for vendors.

For AI-centric startups, this means two things:

Epic intends to build some foundational models themselves.
That doesn’t eliminate opportunities—but the bar for safety and accuracy will keep rising.

Why This Matters for Startups
Startups often struggle with three Epic-related hurdles:

Getting access to the right API
Understanding the approval/onboarding process
Needing a customer sponsor to fully activate integration

Open.epic.com doesn’t magically remove these hurdles, but it reduces uncertainty—and uncertainty is the enemy of innovation.

With clearer pathways, documentation, and examples, a startup can now:

Build a prototype faster
Validate value propositions early
Approach Epic customers with more confidence
Know exactly what is and isn’t technically feasible

In fact, you can list your app in Epic Showroom even without a mutual customer using Epic. In short, the ecosystem is becoming healthier.

Why This Matters for Established Vendors
Established vendors—RCM companies, analytics platforms, AI tools, archival systems, medical device manufacturers—all shared the same pain point when I spoke with them:

“Everything depends on getting the right Epic data.”

Epic’s latest moves help by:

Making API capabilities more transparent
Clarifying security and compliance needs
Providing sandboxes to accelerate proof-of-concept
Aligning with TEFCA and FHIR (reducing future rework)

Predictability lowers cost, reduces risk, and accelerates product strategy.

My Overall Takeaway
Epic hasn’t magically become open overnight. But compared to prior years, the level of structure, communication, documentation, and willingness to engage is materially better.

This is a win for:

Developers
Innovators
Health systems
And ultimately, patients

Healthcare desperately needs interoperable, connected ecosystems. Epic’s steps—imperfect but meaningful—deserve recognition.

And if this trajectory continues, the industry will benefit from a richer, more vibrant innovation landscape.
