It is mandatory to have an account to search and explore on Instagram. You can see videos, posts your content, or see others' account through an account. But if you don’t have an account and want to see someone’s Instagram without an accountthen there are some tools available too.
1. Use the Imginn website to search for someone’s profile. Go to the website and enter the username of the person in the search bar.
2. Next one is Dumpor, type the username in the search bar and hit the enter button.
You can see only public profiles by using these websites. Private accounts will be not visible on the account.
