That depends entirely on the hardware you are running on, and how large
your webinars will be. On a beefy dedicated server BBB can handle 400+
users in a single meeting. You won't reach those numbers on a cheap
cloud VM though.

Thanks Marcel,

I m using on dedicated machine only which has 32 gb of ram and 8 cpu. So i think it can work.

Note, I've updated the release notes of BBB 3.0.19 to include

"contains a security fix https://github.com/bigbluebutton/bigbluebutton/security/advisories/GHSA-8vv7-vj94-q2pv will be made public not earlier than Feb 2, 2026" for one of the items.

I'd encourage administrators to update BBB to 3.0.19.
