Jailarr is a completely open source inmate monitoring application that tracks jail rosters from one or more compatible agencies.

This application periodically checks for new bookings, releases, and updates to inmate records, storing all information in a local database.

Customizable notifications for new arrests and releases are also available and more than 80 notification services are supported.
