As of now, nothing. There is no strong restriction on the number of concurrent users in a room. This might of course change in the future.

But please do not try to organize a meeting with thousands of users on the free tier as this might simply put too much strain on the free-tier architecture.

We are of course monitoring the room sizes, and we will ask you to choose a pro plan if you are often going above the threshold.

Finally, if you are often using WorkAdventure, please consider subscribing to a pro plan. WorkAdventure requires a lot of work and your financial support will help us build more awesome features!
