MEET ALLIGATOR
Less counting pipes.
More understanding.
A viewer and editor for HL7 v2 messages, right inside IntelliJ IDEA. Read the structure, work with individual values and review what changed.
Marketplace release coming soonWork with the value.
Edit values in the Inspector or Segment Grid. Keep the message in view and use the IDE’s normal Undo when you need to go back.
Enter confirm Undo restore
See what changed.
Focus an HL7 comparison to see structured changes and previous values. Return to the file to continue editing.

Your message stays in your workflow. Message inspection and editing run locally in the IDE. Alligator is a developer tool with partial metadata guidance, not a complete conformance validator or a clinical decision system.
TWO PEOPLE. ONE SMALL LAB.
Built from
everyday work.
ChaJa Labz is a collaboration between Chantal Roth and Jan Taralczak.
We turn practical development needs into focused tools. Alligator is our first plugin, shaped by the everyday work of reading, editing and comparing HL7 messages.
Small in scope. Useful in practice. With room for whatever we build next.
Chantal & Jan ChaJa Labz
