Download PrefixHarbor ↗

Download the official PrefixHarbor build for Windows. The standard setup is about 34 MB. A portable single .exe is about 25 MB.

  1. Click the download button to start the installer file.
  2. Compare the SHA-256 checksum with the published manifest.
  3. Run the setup file only after the checksum matches; if SmartScreen warns, select More info, then Run anyway.
  4. Open the app and connect a model to your folder.
Before you begin

No account is needed to run the agent. A cloud model needs an API endpoint and key from your provider.

System requirements

PrefixHarbor runs on Windows 10 or Windows 11 x64. The interface supports 13 languages. A local model runs on your PC and needs enough hardware, and cloud and built-in options exist.

Check for updates

The app shows an Update button when a new version is ready. Click it to install the latest build.

Verify the download

Windows
certutil -hashfile "C:\Users\you\Downloads\<downloaded file>.exe" SHA256

Compare the output with the published manifest. Only proceed if the hash matches the expected value exactly.
