Could anyone recommend any devtools to calculate Monthly Active Users?
Feel free to comment. Preferably, I would like solutions that are easy to integrate, like a simple copy & paste JavaScript code, etc.
Are the users registered in any way (e.g. have accounts)? You could check the login logs.
If not, you could also use something like UXWizz[0] to tag each individual session based on their user ID and then run a MySQL query to get the distinct ones within the last 30 days.
