Facebook Messenger’s source code reveals hidden Rooms feature

Facebook Messenger has built an unreleased feature called Rooms that lets groups publicly chat about different subjects and events. Buried in Messenger’s iOS app’s source code are multiple references to the feature, with some explanation of how it works.

The code shows: “Introducing rooms”, “Rooms are for public conversations about topics and interests. Each room has a link that can be shared so anyone on Messenger can join the conversation”. You can apparently start your own Rooms as well. The blue circle image above is listed as a Rooms logo in the code (the darker background and illustration of a home is ours).

When asked if Facebook was building a Messenger Rooms feature, the company told me “We don’t have any comment on this speculation.” However, here are screenshots of the excavated Messenger code about Rooms:

“Introducing rooms”

“Rooms are for public conversations about topics and interests. Each room has a link that can be shared so anyone on Messenger can join the conversation”

“View room”

“Start your first room about a topic or event that you’re interested in.”

“This will remove you as the host and other members will be able to manage the room. You will no longer receive new messages.”

The Messenger Rooms feature is reminiscent of the standalone Rooms app that Facebook launched in 2014 but shut down in 2015. It let people be pseudonymous and join interest-based discussion groups. It didn’t receive much widespread traction, though, and was removed from the app store.

Rooms might not be available to any users or could be in very limited testing. It might never roll out more widely depending on user reactions. But the feature could help Facebook fill in the middle-ground between broad News Feed sharing to your whole social graph, and private messaging to your closest friends. Rooms could become the Messenger counterpart to Facebook’s popular Groups feature that’s grown to see over 1 billion monthly active users.

Rooms could unlock more engagement on Facebook about niche topics that most of your friends might not care about, but someone out there does. While Groups is great for threaded posts about a topic, those don’t quite feel alive. Rooms could capture the fast-moving, fun conversations that once lived in the chat rooms of web 1.0.
