However, there are some public data analysis tools based on Instagram, which can view some public data, such as the number of fans and the number of posts, without logging in to the account. These tools use public data interfaces instead of directly accessing personal account data. You can search for "Instagram analysis tools" or "Instagram follower tracker" in the search engine to find a list of these tools. Note that these tools may have different functions and limitations, depending on the design and provider of each tool.
No matter which tool you use, please ensure that you abide by the terms and regulations of Instagram and respect the privacy rights of other users.
