Webview Kiosk

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

Is Webview Kiosk free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Webview Kiosk require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Webview Kiosk safe to install?
We link to the exact APK published by Khiet Tam Nguyen. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Webview Kiosk?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded uk.nktnet.webviewkiosk.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «Webview Kiosk» by Khiet Tam Nguyen and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
