5 Best Redox Alternatives to Integrate with EHRs in 2026

Redox solved a real problem. It has 7,000+ integrations across 90+ EHRs. But it is not the right fit for every team. Cost, control, speed and the kind of data you need all push teams to look elsewhere. Here are five alternatives and who each one fits best.

• Many EHRs and payer portals, at any scale: Pick Tross. It reads and writes into EHRs and payer portals through pre-built APIs, so you skip months of custom work for each new system.

• Analytics-heavy payer: Pick 1upHealth. Its FHIR-first, bulk data design suits quality measures and risk adjustment.

• Clinical data network or provider group: Pick Health Gorilla. It pulls patient history from many sources into one view.

• Team with deep HL7 skills: Pick Mirth Connect. You build and run your own channels.

• Hospital system with legacy IT: Pick Rhapsody. It routes high-volume messages across dozens of protocols.

Comparison Table

1. Tross: Pre-Built APIs for Many EHRs and Payer Portals

Tross gets a team from zero to live EHR read and write without hiring HL7 engineers. Pre-built APIs plug into your platform right away, and you can add more EHRs and payer portals as you grow. It also reaches portal-level detail, like claim and denial line items, that standard feeds may not carry.

It writes back too: schedule appointments and upload notes straight into the EHR. It is built for low-latency uses like voice agents, and new platforms are typically integrated within a week. Supported today: Athena, Availity, Elation, eClinicalWorks, EyeMed, EZDerm, Glace, Netsmart, Pear, TherapyNotes, UnitedHealthcare and Zedmed.

2. 1upHealth: Bulk Data and Analytics

1upHealth is FHIR-first and built for bulk data. If you run quality measures, risk adjustment or large-scale analytics across many endpoints, it is purpose-built for that. Redox moves messages. 1upHealth moves datasets.

It supports bulk FHIR export and the CMS interoperability rules, and it has held HITRUST i1 certification. Plan for FHIR mapping and pipeline setup, which pays off at scale.

3. Health Gorilla: A Clinical Data Network

Health Gorilla runs a national clinical data network. It returns treatment history, lab results and medication records through one FHIR R4 interface, and handles identity matching, consent and data agreements for you.

It suits clinical decision support, care gap analysis and provider network management. It is HITRUST r2 certified.

4. Mirth Connect: A Self-Hosted Engine

Mirth Connect, now part of NextGen Healthcare, is an HL7 and FHIR interface engine you host yourself. You build channels: a source connector, your transformation logic and a destination.

It has no pre-built EHR integrations, so you need engineers who know HL7. Recent versions moved to a commercial license, so check current terms and cost with NextGen.

5. Rhapsody: Enterprise Legacy Integration

Rhapsody (formerly Lyniate) is an integration engine for hospital systems with mainframe-era interfaces, DICOM imaging and X12 billing. It supports dozens of protocols and offers mature monitoring and failover.

Large health systems use it to connect Epic, Cerner, radiology and billing platforms. It is owned by the investment firm Hg.

Pick by fit. Tross suits teams that need many EHRs and payer portals, from a first launch to a large rollout. 1upHealth fits payer analytics, Health Gorilla fits clinical data networks, Mirth Connect fits teams with deep HL7 skills, and Rhapsody fits hospital systems with legacy IT.

Frequently Asked Questions

What is the best Redox alternative for teams needing fast, production-ready EHR integrations?

Tross is built for teams of any size that need to read from and write to many EHRs and payer portals quickly. It offers pre-built APIs that go live within a week and writeback that includes scheduling and note uploads.

How does Tross compare to Redox in terms of security and compliance for healthcare data?

Both handle protected health information, so judge them on the same checklist: a signed BAA, current third-party security certifications, audit logging, and how data is stored and accessed. Ask each vendor for its current reports instead of relying on a comparison article. Among the other options here, 1upHealth holds HITRUST i1 certification and Health Gorilla holds HITRUST r2 certification.

How quickly can a new EHR integration be set up with a Redox alternative, and which is fastest?

Tross reports that new platforms are typically integrated within a week. 1upHealth and Health Gorilla need provisioning and data mapping, which adds setup time. Mirth Connect and Rhapsody need engineering work, and projects can run for months.

Are there Redox alternatives that can both read and write data into EHRs, including scheduling and note uploads?

Yes. Tross supports scheduling appointments and uploading notes directly into EHRs. Redox offers EHR writeback, and Rhapsody can route writeback messages across legacy protocols. Write support varies by vendor and resource, so confirm what you need with each.
