FreeKiosk Cloud is a companion service that manages a fleet from a web dashboard: live status, configuration pushed to devices or groups, remote commands and screenshots. A tablet can be enrolled by scanning a QR code, and a factory-reset tablet can be provisioned end to end from the Android setup wizard.
The cloud is in open beta, with self-service sign-up at cloud.freekiosk.app: the first device is free, then it is priced per device (see freekiosk.app/cloud and the cloud guide). The free device has the whole service except APK distribution, remote screenshots, the scheduler, renaming the organization and additional team members, which come with the first paid licence. The app itself, v2.0.0, is stable. Some cloud paths (over-the-air app updates, QR provisioning, Lock Mode behaviour on every model) have not been proven across enough real hardware for us to call the cloud finished.
Digital signage is in beta on both sides: build a playlist of videos, images, web pages and YouTube videos in the dashboard and a screen plays it, with schedules and from an offline cache (web pages and YouTube need the network). It needs the app v2.1.0-beta.1, a GitHub pre-release (Google Play still has 2.0.0), and also runs on Android TV, Google TV and Fire TV, tested on emulators only so far. Details and limits: Digital signage.
The app itself is unaffected. FreeKiosk stays free and MIT licensed, and the cloud is entirely opt-in: nothing leaves the device until you enroll it. Every kiosk feature, the REST API and the MQTT integration work exactly as before without a cloud account, and always will.
Note
The management server will be released as open source in 2027, so you can self-host it. That is the intended end state, not an afterthought: a kiosk platform you cannot host yourself is only half free. We are holding it back until it is stable and feature-complete rather than publishing something that would be painful to run.
