MLLP TCP Anonymizer Routing Rules Compare View Batch Sending

HL7Forge application window showing the raw HL7 editor, sidebar, and activity log

Everything you need to test an HL7 interface

Send & receive

Send messages over MLLP or raw TCP to any endpoint, with full ACK/NACK capture and round-trip timing. Built-in listener catches inbound messages for testing your own integrations.

Edit your way

Raw HL7 editing, a structured field editor, and a fully parsed segment view. Query view for structured lookups, and a side-by-side compare view to diff two messages.

Batch mode

Load a whole file of messages, step through them, insert, delete, or append, and send the entire batch in one go.

Built-in message library

Ready-made templates across ADT, ORU, ORM, SIU, MDM, MFN, REF, and ACK, so you can generate a realistic message in one click.

Anonymizer

Strip or scramble identifying fields (name, MRN, DOB, and more) before sharing a message with a colleague or vendor, with save-able presets.

Routing & automation

Define conditional routing rules by MSH, PID, PV1 fields and more, to forward, log, or drop messages. Useful for simulating interface engines.
