Multi-Login — Per-Tab Session Isolation

Tired of logging out and back in just to switch accounts? Multi-Login gives each tab its own isolated session, so you can be logged into Gmail, Twitter, GitHub, or any site with multiple accounts — all at the same time, in the same browser window.

How It Works

Each isolated tab gets its own virtual cookie jar and storage namespace. Your sessions are completely separated — no cross-contamination between tabs.

Key Features

- Isolate any tab with one click from the popup
- Open a new pre-isolated tab instantly
- Right-click any link to open it in an isolated tab
- Isolated tabs show a green badge so you always know which ones are active
- Links opened from an isolated tab automatically inherit the parent session
- Sessions are ephemeral — close the tab and all traces are gone

What Gets Isolated

- Cookies (including HttpOnly)
- localStorage
- document.cookie
- IndexedDB

Privacy First

No data leaves your browser. No accounts, no servers, no tracking. Sessions live entirely in memory and are destroyed when you close the tab.

Use Cases

- Manage multiple email accounts side by side
- Test web apps with different user roles
- Keep work and personal accounts separate
- QA and development testing

Perfect for developers, social media managers, QA testers, or anyone juggling multiple accounts.
