What it is

Wintertrace documents winter service work, recording GPS tracks, weather data and photos and turning them into PDF service proofs. It is aimed at operators who need records of completed operations, not tools for order management, route optimisation or ERP. Drivers can send location data from the free OwnTracks app on iOS or Android directly to an installation over HTTPS, without an intermediate cloud. Weather is gathered automatically at the start and end of operations; Open-Meteo is the default provider, with Bright Sky and MET Norway also available. Clients can use a portal to view their operations and weather, optionally see GPS tracks, and download past proofs. Email alerts can cover starts, ends and exceptions, with a notification log. Data tools include driver-data anonymisation, configurable retention, and CSV and PDF export. The self-hosted open-source core is listed at free. Hosting requirements include PHP 8.4.1 or newer, MySQL 5.7+ or MariaDB 10.3+, and a cron job every minute. There are no artificial driver, customer or operation caps; hosting capacity sets the limit.
