Pidgeon ships five Windows desktop apps: Post, Flock, Loft, Migrate, and the Pidgeon launcher. Each is a separate installer. Install only what you need; the launcher can detect and open the others later. Current beta release: 0.2.0-beta.1.

​
Requirements

  • Windows 10 or Windows 11, 64-bit
  • No admin rights required for a per-user install
  • AI features (optional) run on-device and recommend 16 GB RAM; everything else runs comfortably below that

​
Download and install

1

Download from the catalog

Get installers from the downloads catalog at downloads.pidgeon.health. The catalog lists every app, its current version, and a SHA-256 checksum per file.Download the .exe installer for each app you want.
2

Verify the checksum (optional but recommended)

Compare the output against the checksum shown in the catalog. If they differ, do not run the installer: re-download, and contact [email protected] if it still differs.
3

Run the installer

Each installer is Authenticode-signed under the verified publisher Pattern Engine LLC (SHA-256, timestamped). When Windows shows a publisher, it should read Pattern Engine LLC, never “Unknown publisher”.If Microsoft Defender SmartScreen shows a “Windows protected your PC” prompt, see What to expect from SmartScreen below. Click More info, confirm the publisher reads Pattern Engine LLC, then Run anyway.
4

First launch

Each app starts its local Bridge sidecar (the engine process) on a loopback port: Loft on localhost:5100, Post on localhost:5101, Flock on localhost:5102. The Bridge binds to loopback only; nothing listens on your network.Post works without an account. Flock, Loft, Migrate, and the launcher ask you to sign in with your Pidgeon account.

​
What to expect from SmartScreen

SmartScreen reputation is earned from download volume across a wide audience, and Pidgeon is a focused tool for healthcare integration teams. So early in the beta you may see the SmartScreen prompt even though every installer is signed by a verified publisher. That prompt is not a signature problem; it fades as installs accrue under the Pattern Engine LLC identity. As of August 2024 no certificate type clears SmartScreen instantly (Microsoft removed the instant-reputation advantage EV certificates once had). To check a signature yourself before running anything:
  1. Right-click the .exe, open Properties, then the Digital Signatures tab.
  2. Select the signature, click Details, and confirm the publisher name is Pattern Engine LLC and the signature is valid.
  3. Confirm a timestamp is present.
If the Digital Signatures tab is missing or the publisher name is wrong, do not install. Contact [email protected].

​
Deploying to a managed fleet

If you are rolling Pidgeon out across a Windows fleet, you can skip the interactive SmartScreen prompt entirely:
  • Intune / SCCM / GPO: push the signed installers through your existing management tooling. Apps deployed by an administrator do not trigger the interactive prompt.
  • Trusted source: host installers on an internal share or portal mapped to the Local intranet or Trusted sites zone, so downloads carry no Mark-of-the-Web.
  • SmartScreen policy: on managed devices, configure Defender SmartScreen enforcement via Intune settings catalog or Group Policy to match your risk posture.
