Hosting
The platform is run on servers at Hetzner in Germany. Uploaded images and audio files are saved in the Object Storage at Scaleway in Paris and delivered directly from there. Hetzner and Scaleway both use 100% renewable energy for their data centers.
Server-side software
The application uses the Play Framework 2.8 and is written in the programming language Scala. We use the database mongoDB.

For the frontend, we use CoffeeScript for some legacy components and
Typescripe with Preact for newer components.
The following JavaScript libraries are used:
- jQuery (plus some jQuery plugins)
- Lodash
- jPlayer for playback of audio tracks
- FileUploader for AJAX file uploads
- some other small libraries
For the styling of web pages, we employ SASS and BULMA.
For the displaying maps, we use the Google Maps JavaScript API and MapBox.
Android App
The Android app is developed with Android Studio in the programming language Kotlin. For displaying maps, we use MapBox.
iPhone App
The iPhone-App is a completely native app, written in Objective C and Swift with XCode.
As a map service, we use MapBox.
