Wintertrace
Wintertrace records winter service operations using GPS tracks, weather data, and photos, then creates PDF service proofs.
What Wintertrace is
Wintertrace records winter service operations using GPS tracks, weather data, and photos, then creates PDF service proofs. Its focus is documenting completed work; it is not an order management system, route planner, or ERP. Drivers can send location data from the free OwnTracks app for iOS or Android directly to a Wintertrace installation over HTTPS, without an intermediate cloud. Weather is collected automatically at the start and end of an operation, using Open-Meteo by default, with Bright Sky and MET Norway also available. A customer portal lets clients view their operations and weather, optionally see GPS tracks, and download earlier proofs. Email notifications can cover starts, ends, and exceptions. The free, open-source core has no artificial driver, customer, or operation caps, though hosting capacity limits use. Self-hosting requires PHP 8.4.1 or newer, MySQL 5.7+ or MariaDB 10.3+, a cron job every minute, and disk space for the application and photos. A demo installation is available for 48 hours.

Who it suits
Wintertrace suits winter service operators who need records and proof of completed operations. It is for teams prepared to host and maintain the system rather than seeking route planning or ERP functions.
Verdict
Wintertrace concentrates on recording service work and sharing proof with clients, rather than managing the wider operation. Its free core may suit operators able to meet the hosting requirements and accept email support without an SLA.
