Deskreen vs Extron ShareLink Pro

Deskreen is a desktop app that mirrors a computer screen or one application window to a device’s browser over Wi-Fi. With a Virtual Display Adapter, a browser-equipped device can serve as a second screen. It can work off-grid over local Wi-Fi without internet access, and Flip Screen Mode horizontally flips the image in a tablet or smartphone browser for teleprompter use. During sharing, users can change picture quality, with automatic quality changes also supported. Community is free, open source under AGPLv3, and supports one connected device. Pro costs $24.99 a year and supports up to five connected devices; Teams costs $139.99 a year and supports unlimited devices, with three seats included for teams of up to 20 members. Extra Teams seats cost $10 each. Custom terms are available for enterprise, education, and large organizations. Deskreen says it uses end-to-end encryption; enhanced connection security and VPN support are listed for Pro, Teams, and Custom. Its listed desktop systems are Windows, Linux, and macOS.

Extron ShareLink Pro is an app for sharing images, video, and device screens wirelessly to a room display through an Extron ShareLink Pro presentation system. The system can show up to four pieces of content at once. Collaboration mode allows any user to share, while Moderator mode gives a designated moderator control over who presents. The app supports Apple and Android smartphones and tablets; the system also works with macOS and Windows computers. Android devices connect through the existing Wi-Fi network. Extron says content sent between devices and the system is encrypted, and a Welcome Screen Display ID Code helps direct content to the intended display. Extron GVE can centrally manage setup, configuration, and firmware updates across multiple units. The app is free, but requires an Extron ShareLink Pro presentation system. It is listed for iOS, Android, macOS, web, and Windows. Extron lists 24-hour technical support at its Anaheim worldwide headquarters and says product pricing information is available to Extron Insider customers.
