Screenleap vs ViewSonic AirSync

Screenleap lets people share a screen or camera with viewers who can join in a browser without installing software. Screen sharing is available through Windows and Mac apps, desktop browsers, and native iOS and Android apps. Meetings can use computer audio through the sharer’s microphone and speakers. Users can share computer control and let viewers point things out on screen, though those features require add-on software. Premium account users can record screen shares for later download, viewing, and sharing. Website integration adds screen sharing, video, audio, chat, and other live interaction to a site; the API can start live sessions without participant software. Integration requires HTTPS and a modern browser, and mobile or tablet visitors can view but not share through it. The Free plan costs nothing, runs 40 minutes per day, and allows up to 8 viewers. Basic costs $15 a month; Pro costs $31 a month; Company costs $1,539 a month. Screenleap says data is encrypted in transit and cleared from memory two minutes after a share ends.

ViewSonic AirSync mirrors a device screen wirelessly to ViewSonic displays through a sender app or web browser. It supports AirPlay, Google Cast, Miracast, and AirSync Sender screen sharing. Hosts can moderate requests, while multiple presenters can share screens at once; capacity varies by IFP model from four to six. Display Grouping can broadcast one display to as many as 10 ViewSonic screens on the same local network segment. AirSync supports LAN and internet connections, but Web Sender is limited to internet connections and lacks touch feedback, incoming IFP screens, pen strokes, and high-quality sharing. The Sender app offers touchback from compatible ViewBoard displays on Windows, macOS, Android, and iPad. ViewSonic describes end-to-end encryption and centralized control through ViewSonic Manager. AirSync is intended for ViewSonic displays; specified older CDE and IFP models continue with myViewBoard Display and vCast. Sessions last 180 minutes by default and can be extended twice, up to nine hours. Pricing starts at $62, and a free plan is listed.
