If you want to view someone’s Snapchat story without them knowing, you’d be bummed to learn that Snapchat doesn’t provide you with any such feature. However, you can follow the listed methods below to view Snapchat story online without the user knowing:
Using the Snapchat apps Discover feature
Turning off your mobile data or wifi before checking the Snapchat user’s story
Creating another Snapchat account (they won’t be able to know it’s you checking their snaps)
Using Snap Map
Utilizing Snapchat story viewers such as Snapchat Phantom or Snapchat ++
Using a spy app (mSpy)
By choosing any of the mentioned options for Snapchat viewers, you can watch Snapchat stories anonymously.
