If you work with HL7, FHIR, or NCPDP, you’ve probably spent hours creating test messages by hand, copied production data you shouldn’t have, or discovered an interface was down because a nurse called. Pidgeon replaces all of that.

​
Four Products, One Engine

Post

Testing & Validation — Generate HL7 v2.3–v2.8, FHIR R4, and NCPDP SCRIPT messages in seconds, validate against the published spec or real vendor patterns, de-identify on-device. Includes Conform, the FHIR implementation-guide conformance checker.Free generation and validation, no account required. Pro unlocks the Workflow Wizard, Diff, AI Triage, and full datasets.

Flock

Synthetic Population Engine — Seed test databases with schema-aware, FK-safe patient populations. Compliance signs off in minutes because there’s no PHI to review.Output as SQL, CSV, HL7 streams, or FHIR Bundles.

Loft

Interface Observability — Loft watches your configured sources, flags suspect interface messages for human review, and alerts your team. Every catch lands in a review queue with a suggested fix.Built for teams running Mirth, Rhapsody, and similar engines.

Migrate

FHIR Bulk Data Migration — Move healthcare data between systems via FHIR R4 Bulk Data Access (NDJSON per the HL7 IG), with preflight checks, de-identification, reconciliation, and resume.Built for migration projects, not synthetic test data.
Post, Flock, Loft, and Migrate are desktop apps, opened directly or through Pidgeon — the launcher app that shows every product’s install and entitlement status in one grid. See Get started with Pidgeon (the launcher).

​
How the Products Connect

All four products share a core engine — configure it once, use it everywhere:
  • Shared parsing and validation — The same HL7/FHIR/NCPDP parsers power Post’s validation, Flock’s output, Loft’s message analysis, and Migrate’s conversion
  • Shared de-identification — On-device PHI removal available across every product
  • Shared vendor profiles — Learn your vendor’s patterns once, apply them across generation, validation, and monitoring
  • Cross-product workflows — Generate a population with Flock, test the messages with Post, monitor the feed with Loft
Each product has its own buyer and budget — this is a shared engine with a retention story, not a purchasing pipeline you walk end to end.

Who Is Pidgeon For?

Integration Engineers

Stop hand-crafting test messages. Generate realistic data on demand, validate against your vendor’s actual patterns, and go into go-lives prepared.

Consultants

Carry your testing toolkit from client to client. Vendor profiles are portable across engagements — no more starting from scratch at every new site.

IT Directors & Compliance

Eliminate PHI from test environments without a 4-month approval process. Monitor interface health from a single dashboard instead of waiting for incident reports.

QA & Testing Teams

Seed test databases that look like production in minutes. New developers are productive on day one instead of spending their first week building test data.

Free CLI, desktop apps for everyone else

  • CLI — Always free. Install the Pidgeon.CLI tool with dotnet tool install --global Pidgeon.CLI --version 0.1.0-beta.1 and you’re generating messages in under a minute.
  • Desktop apps — Post, Flock, Loft, and Migrate for the majority who’d rather point and click. Post’s core loop (generate, validate, conform) works with no account; Post Pro starts at $29/mo, and Flock, Loft, and Migrate require a Pidgeon account sign-in.
