Digitransit is an open-source journey planner for public transport in Finland, covering routing, maps and geocoding. It is developed jointly by HSL (Helsinki Region Transport), the Finnish company Waltti Solutions Oy and Fintraffic, and forms the basis of Finland's main route and timetable service. Its components include a user interface, map tiles, geocoding and data conversion tools, and route planning runs on OpenTripPlanner. The components are published as open source on GitHub.
The source code is dual-licensed under the EUPL-1.2 and the AGPL-3.0, both open-source licences, so an organisation can run the components on its own infrastructure. The platform is an alternative to commercial journey planners with public-transport routing, such as Citymapper. The developing organisations are Finnish, and no foreign owner is named. The developers' pages do not state where the service's data is hosted, so for a European organisation the relevant facts are the development within the EU and the open licences.
