walkerOS: sovereignty score and 8 European alternatives

walkerOS is an open-source toolkit for first-party event tracking. It collects events from websites and servers, validates and enriches them, applies consent rules, and routes them to analytics tools, advertising platforms and data warehouses. The code is published on GitHub under the MIT licence. It can be bundled into a script for static sites, run in Docker or used in a CI/CD pipeline, so an organisation can operate it on its own infrastructure.

The project is developed by elbwalker GmbH, based in Hamburg, so the maintainer is subject to EU law and German data protection rules. The MIT licence allows a European organisation to inspect, modify and run the software without relying on a vendor cloud. The vendor's website does not state where its software or any hosted service runs. Teams that use a hosted service built on walkerOS should check where it stores data.
