Multi-Session

Log into multiple accounts on one site using separate, cookie-isolated browser tabs.

Multi-Session lets you open multiple logged-in sessions of the same website in one browser. Click the icon and a new tab opens with its own empty, isolated cookie jar — log into a different account there and it stays separate from your other tabs, even on the same site. Each tab gets a small numbered badge so you always know which session it is. Handy for managing multiple accounts on one platform, juggling client logins as a freelancer or agency, testing different user roles as a developer, or checking a customer's view without losing your own session. Cookies never cross between tabs, and closing a tab clears that session completely. No account needed, no data collected — everything runs locally in your browser.
