While there is no limit on event registrations, the number of attendees for free webinars is capped.
For all free registrations on webinars, series and events, there isn't a limit on the number of people who can register for your webinar. However, there is a limit on the number of people who can attend your webinar. Additionally, if you charge people to register for your content, then there will always be a registration capacity that is enforced.
By default, that number of attendees and how many paid registrations you can sell for your event is based on the BigMarker plan you choose.

Custom capacity
For any webinar or series, you can set a custom registration or attendance capacity. Visit the edit settings and go to the Webinar Size section to configure this.
