Video calling and virtual meetings have become our new normal during this pandemic, and everyone from Zoom, to Microsoft, to Google wants a piece. Today Facebook threw its hat into the ring by announcing Messenger Rooms, bringing massive improvements to its chat app‘s video capabilities — including the ability to support up to 50 participants at once.

Massive meetups aside, one of the key differences between Messenger Rooms and regular Messenger video calls is that you don’t have to download an app — or even have a Facebook account — to join. Just click on the link and you can join on the fly — though Zuckerberg did note that using the Messenger app provides “the best experience.”
