Comparative Analysis of
Leading EHR Platforms
With a new dimension: Coding Agent Readiness.
An update to the 2025 Cara EHR Comparative Analysis. 21 EHRs evaluated across eight dimensions — including the first published framework for evaluating EHRs as platforms for AI coding agents. Separate evaluation of the interoperability layer. 70+ primary sources cited.
Executive summary
A year is a long time in healthcare technology. Since we published the first edition, four forces have reshaped the EHR landscape: generative AI has moved from pilot programs into production clinical workflows; ambient-scribe and agentic billing features have become baseline expectations; venture capital has crowned a new wave of AI-native and developer-first EHRs; and, most consequentially, large-language-model coding agents have become the primary way many healthcare technology teams extend their EHRs.
The 2026 edition keeps the seven original evaluation dimensions and adds an eighth that reflects how healthcare software is increasingly built: Coding Agent Readiness. This new dimension measures how well a platform supports being integrated and extended by an AI coding agent such as Claude Code, Cursor, Copilot, or Devin — a deliberately practical axis.
The headline finding: the gap between AI-marketing EHRs and AI-native EHRs widened sharply in 2025–26. Legacy systems now ship capable ambient scribes, but the platforms that have genuinely built for autonomous-agent development — Canvas Medical, Healthie, Oystehr, and Medplum — are meaningfully ahead for the teams most likely to shape the next decade of care delivery.
The eight dimensions
What we measure — and why.
API Readiness
The shape of the developer surface — FHIR, REST, SDKs, rate limits.
Virtual Care Readiness
Native support for telehealth, async workflows, and modern visit types.
Scalability
Proven capacity at the level of health system or large digital-health operator.
Maturity
Operating history, customer base, and regulatory posture.
AI Readiness
Native AI features shipped by the vendor — ambient documentation, chart summarization, agentic workflows.
Customizability
Ability to modify platform behavior — plugins, SDKs, open source.
Security
HIPAA, SOC 2 Type II, HITRUST, BAA posture, audit-trail quality.
Coding Agent Readiness
New · Cara-pioneeredHow navigable the platform is for an AI coding agent acting with limited human-in-the-loop. New in the 2026 edition.
The tier list
Coding Agent Readiness — April 2026.
A snapshot. MCP adoption in particular is fluid; we expect multiple vendors currently in Difficult to announce first-party MCP servers by late 2026.
Excellent
Score 80–100
Platforms that treat their API as a developer product first and an EHR second. First-party MCP servers, typed SDKs, self-serve sandboxes.
- Healthie90
- Canvas Medical88
- Medplum85
- Oystehr82
Good
Score 60–79
Platforms with meaningful agent-friendliness within their scope — clean REST surfaces, documented webhooks, functional documentation.
- Hint Health75
- Akute Health62
Workable
Score 45–59
Platforms an agent can integrate with, but with real friction — partial FHIR, sales-gated sandboxes, fragmented documentation.
- Elation Health55
- Epic48
- DrChrono46
Difficult
Score 25–44
Platforms with real integration gates — partner certification, HITRUST self-assessment windows, IP-locked sandboxes, PDF-only docs.
- Oracle Cerner42
- Cerbo40
- Athenahealth38
- NextGen34
- ModMed32
- MEDITECH Expanse28
Avoid for agents
Score ≤24
Platforms with no practical self-serve path for an AI coding agent today — approval-based access, no sandbox, or no public API surface.

- AdvancedMD20
- Tebra18

Disclosures
This paper is produced by Cara, a company building AI-native healthcare applications. Several of the dimensions we score — most directly Coding Agent Readiness — map to capabilities that matter to our own engineering. Readers should read this as editorial analysis from a commercially-positioned author, not a neutral analyst report.
We have no paid relationship with any vendor covered and accept no payment for inclusion, ranking placement, or removal; but we do not claim to have independently audited vendor claims, and several of our favored platforms are ones we have built or would build on ourselves.
Dollar amounts and pilot-program metrics are vendor-reported unless otherwise cited and should be confirmed directly with the vendor or regulator before any procurement decision.
