Webview Kiosk is a free and open-source Android application for secure, kiosk-style web browsing.

It can function as digital signage, a kid-friendly restricted browser, an immersive web reader, an interactive sign-up form, a home assistant dashboard, or simply a wall clock.

Designed for small businesses and device owners who are looking for a simple and standalone Kiosk solution.

Key Features

Core / Standalone

- Lock Task Mode (Pin): prevent access to your device's home screen, apps and status bar
- Secure Settings: configurations are protected by biometrics, device credentials or custom password
- URL Filtering: use regular expressions to control web access through a URL blacklist and whitelist
- Export/Import: backup and restore user settings in Base64 or JSON format
- Local files: display images, audio, video, HTML or PDF (using Mozilla's PDF.js) in kiosk mode
- Default Launcher: use as the home app and launch other apps in lock task mode (kiosk)
- JS Scripts: supports NFC (Near Field Communication), Eruda console, Dark Reader and custom scripts

Remote Management / Enterprise

1. MQTT (Message Queuing Telemetry Transport)

- Monitor events, update settings, execute commands and build custom automations using the API
- Requires an MQTT broker (e.g. Mosquitto, EMQX, HiveMQ, or their HomeAssistant integrations)

2. UnifiedPush

- Send commands and update settings via a decentralised push notification system
- Requires a distributor application (e.g. sunup, ntfy, gCompat-UP)

3. Managed Configurations (App Restrictions)

- For fully-managed (company-owned) devices, settings can be remotely configured via an MDM/EMM provider
- Advanced users using a device policy controller (e.g. Test DPC or OwnDroid) can also enforce configurations locally
