Kosmi gives you a shared virtual browser everyone can see and click in — plus video chat, screen sharing and games in the same room. Free, nothing to install, and guests join from a link.
Both give you a browser that a group can share. The difference is what surrounds it.

The virtual browser is one thing in the room, not the whole product.
Open a shared browser in the room and everyone sees it, clicks in it and types in it. Streaming sites, YouTube, a shopping cart, a map — whatever you'd browse alone, browsed together.
Video and voice chat are in the same room as the browser, free. Co-browsing without seeing each other is a screen share with extra steps.
Share your actual desktop or a window, with system audio, when the thing you want to show isn't on the web.
Poker, Cards Against Humanity, drawing games and NES, SNES and PlayStation emulators, for when the browsing is done.
Kosmi. It gives you the same shared virtual browser — a browser window everyone in the room can see, click and type in — and adds video chat, screen sharing and multiplayer games around it. Rooms are free and guests join from a link without an account.
Yes. Open the browser in a Kosmi room and everyone in the room sees the same page and can interact with it. It streams as video, so people on phones and slower machines see the same thing as everyone else.
Hyperbeam is built mainly as an embeddable virtual browser for developers to put inside their own apps. Kosmi is the app: the browser is one feature in a room that already has video chat, screen sharing, watch parties and games in it.
Yes. Rooms, the shared browser, video chat and the games are free. Kosmi Premium covers extras like 1080p screen sharing, not the basics.
No. The room runs in the browser and guests join straight from the link with no account and no extension, on desktop or phone.
Yes. Open a streaming site or YouTube in the room's browser and everyone watches the same thing in sync, with video chat running alongside it.
