AltDisplay

AltDisplay is a browser-based screen sharing application that requires no downloads or installations. Hosts can share an entire screen, a specific window, or a browser tab, and invite viewers by email, SMS, or direct link. Sessions include microphone support for voice communication and a built-in whiteboard for drawing and annotation. Screen recording is also listed. The service is available on web and iOS, but mobile browsers can join sessions rather than host them, and mobile screen sharing is not supported. Listed desktop browser requirements are Edge 79 or later, Chrome 56 or later, Firefox 44 or later, and Safari 12 or later. The Basic plan costs $9.99 a month and includes unlimited meetings, up to five participants, a 30-minute meeting limit, and standard VGA quality. Premium costs $14.99 a month and Professional costs $19.99 a month, with higher participant and meeting-time limits. The site says there are no contracts and customers may cancel, upgrade, or downgrade at any time; it also invites customers to ask about custom plans.

AltDisplay offers browser-based hosting with voice communication, annotation, and session recording. Check the mobile hosting limit and the participant and duration caps in the selected plan.

AltDisplay suits people who want browser-based screen sharing for meetings with up to five participants on the Basic plan. It may also fit users who need voice chat, a whiteboard, or session recording, provided they do not need to host from a mobile browser.
