Problem

• Developer wants to test different users on different URLs
• Developer is working on a web app (or a website) that supports multiple users
• Different pages looks completely different for an admin user, a regular user, or a logged out user
  • Developer wants to log in with “admin@gmail.com” and browse the localhost:3000/admin page
  • Developer wants to log in with “user1@gmail.com” and browse the localhost:3000/purchases page
  • Developer wants to browse the localhost:3000 page (home page) with no logged in user
• Developer wants to make changes to their code and compare the differences between the pages

In other browsers

• It takes way more time to do this
• Developer has to either:
  • Open an incognito window, put the windows side by side, open different URLs
    • Downsides
      • this limits the user to 2 user sessions: regular and incognito
      • Next time they close the incognito window their session and credentials will be lost, they have to log in again
  • Open a guest or another profile in their browser
    • Downsides
      • If user is working on multiple projects their list of profiles is going to be huge and messy
      • A profile is always opened in a separate window, so a mess of window occurs

In Sizzy

• Disable navigation sync between devices
• Open 2-3 devices in Responsive Mode (horizontal layout is ideal)
• Click on the URL bar of an individual device in order to change the URL
• Change sessions of each device to Guest, Admin, No User, etc.
