Sure, you can use third-party websites or applications to view Instagram stories anonymously. One popular tool for that is ‘storiesig.com’. Simply type the user’s name and you’ll be able to see their stories without them knowing. Please keep in mind, however, to respect the privacy and consent of others when using such tools for research. Remember also that sometimes these services may not work as Instagram updates its privacy policies. May I ask what type of research you’re conducting that involves viewing someone’s Instagram story?
