The Google Chrome change looks like the most significant of the two factors that caused Portal to shut down, although it's a shame that they didn't continue running the service for users of other browsers. (Android file transfer apps that implement scoped storage have similar functionality as before if users grant them access to the entire "sdcard" directory.)<p>Here are some FOSS alternatives to Portal that don't depend on Chrome:<p>- ShareDrop (<a href="https://www.sharedrop.io" rel="nofollow">https://www.sharedrop.io</a>): WebRTC-based P2P file transfers through the browser<p>- Sharik (<a href="https://github.com/marchellodev/sharik" rel="nofollow">https://github.com/marchellodev/sharik</a>): File transfers via Wi-Fi or mobile hotspot for Android, iOS, Linux, and Windows<p>- KDE Connect (<a href="https://kdeconnect.kde.org" rel="nofollow">https://kdeconnect.kde.org</a>): File transfers, notification sync, and other integrations between Android, Linux, Windows, and SailfishOS.
