OpenPWA Demo

OpenPWA Demo is a free, installable web app for checking PWA capabilities on the browser and device you use. Inspect installation and display-mode status, try offline behaviour, and explore browser API demos with their support and permission requirements explained. It accompanies the OpenPWA reference, which publishes compatibility notes and reproducible device studies with source links, raw data and screenshots. No account is required. Checks run in your current browser; it is not a remote device grid or a third-party website scanner. Results depend on the browser, operating system, installation state and permissions.
