What is the maximum number of active users registered simultaneously on your last project?

The maximum number of simultaneously active users depends on the project's specifics, infrastructure, and load. For example, for a mobile application, this could range from a few hundred to millions of users.

An active user is someone who interacts with the application during a certain period (for example, within an hour or a day). In a real project, this number is measured using analytics and monitoring.

Speaking from experience, in small projects, this could be a few hundred, while in large projects, it could be tens or hundreds of thousands of simultaneously active users.
