What is complete and what is experimental
| Feature | Status | Notes |
|---|---|---|
| HL7 Inspector | Available | Structural parsing. Not a conformance validator. |
| Message Diff, occurrence pairing, segment/field/component/subcomponent diff, counts, order | Available | Textual comparison; never claims equivalence. |
| Message Diff, ignore rules | Available | Pro plan. |
| Message Diff, aligned pairing | Experimental | Heuristic; falls back to occurrence pairing for very large groups. |
| HL7-to-JSON (full and compact styles, copy, download) | Available | Lossless structure; no field names or type conversion. |
| Mirth helper | Experimental | Illustrative output; depends on your Mirth version and channel settings. |
| Plan limits and usage metering | Available | Server-side. Checkout is not connected. |
