01
Missing proof when a claim arises
When someone slips on an icy walkway, the operator bears the burden of showing that service was performed. Paper logs often fall short of what is required.
Open source · Self-hosted
Document winter service operations.
Automatically.
Wintertrace captures every snow removal and de-icing operation with GPS track, weather data, and photos. Generates a PDF service proof. Runs on standard web hosting. Open source. No subscription.

Wintertrace is open-source software that documents winter service operations digitally. It runs on standard web hosting with PHP and MySQL — no cloud, no subscription, no vendor lock-in. The source code is public on GitHub.
Three problems that keep operators awake
Real operational pain points — collected from small and mid-sized winter service businesses.
02
Spreadsheets and texts become unmanageable
Three drivers, twelve customers, four shifts a week. By the time anyone asks a question weeks later, the information is gone.
03
Cloud software ties you to the vendor
When your data sits with the provider, the provider sets the terms — price, availability, export options.
Wintertrace flips this: documentation runs automatically, data stays with the operator, the software belongs to the business.
Core features

Frequently asked
A short selection. The full FAQ covers installation, GPS, weather, data protection, liability, features, updates, and open source.
What does Wintertrace cost?
The core software is free and open source under GNU AGPLv3. Additional costs are limited to the web hosting most businesses already have.
Do I need my own server?
Standard web hosting with PHP 8.2 or higher and MySQL is sufficient. No root access, no Docker, no special hardware.
How does GPS tracking work without a cloud?
The free OwnTracks app on the driver phone sends location data directly to your installation. There is no third-party cloud in between.
Is Wintertrace GDPR-friendly?
Wintertrace includes data protection tools — anonymisation, retention policies, data export. The actual compliance is established through correct usage in your organisation. Wintertrace is not a substitute for legal advice.
