Right now, I am doing a little market research for a school project, and I need to check out brands Instagram pages and their activity, but I do not want to log in with my own account or create a fake profile. I have heard there are services that let you browse Instagram without logging in which ones have you used?

When it comes to basic market research, there is really no need to bother with sign ups or fake accounts it will just take up a ton of time. The open instagram private account viewer is perfect for gathering analytics and monitoring brand activity. The main feature is that it works as a guest player directly through your browser. You can easily explore the content of dozens of companies in a row without logging in. For your school project, this is the simplest tool.
