It is not possible to see who has viewed your Facebook profile. Facebook does not provide such a feature, and any third-party apps or websites claiming to do so are likely scams or phishing attempts.
While you can see the number of people who have viewed your Facebook profile, you cannot see the identities of those individuals. Facebook only allows you to see who has interacted with your profile, such as who has liked or commented on your posts.
It’s important to be cautious of any websites or apps that claim to provide this feature as they may be attempting to steal your personal information or login credentials. It’s always best to stick with official Facebook features and avoid giving out your personal information to untrusted sources.
