I've also been curious about this and from what I've found, Instagram doesn't officially allow you to see who views your profile, it's just not a feature they offer. There are some third-party apps that claim to show you this information, but I'd be wary of using them as they often require access to your account and may not be secure. Some of these apps might also be against Instagram's terms of service, so it's not worth the risk. I think it's best to just focus on creating engaging content and interacting with your followers, rather than trying to track who's viewing your profile.
