MultiLogin Tabs

About

MultiLogin Tabs lets you run multiple accounts on the same website — in the same browser window, without incognito mode or separate profiles.

HOW IT WORKS
Open two (or more) tabs of the same site. Assign each tab to a named session (e.g. "Admin", "User1", "Tester"). Each session gets its own fully isolated environment. Log in with different accounts — they will never interfere with each other.

WHAT GETS ISOLATED
• Cookies — both HTTP (Set-Cookie) and JavaScript (document.cookie) are intercepted and stored per-session. Each tab sends only its own cookies.
• localStorage — transparently proxied with per-session key namespace. Apps see their own data only.
• IndexedDB — database names are prefixed per-session, so each session has its own databases.
• Cache Storage — cache names are isolated per-session. PWA caches and offline data stay separate.

USE CASES
• QA / Testing — test multi-role workflows (admin + user + guest) without switching profiles or browsers.
• Development — debug OAuth flows, SSO, or multi-tenant apps with multiple accounts side by side.
• Social media management — manage multiple accounts on the same platform simultaneously.
• Customer support — log in as different users to reproduce issues without logging out.

KEY FEATURES
• One-click session assignment via the popup
• Named sessions with color coding
• Works on any website — React, Angular, Vue, server-rendered, static pages, anything
• Sessions persist across page reloads (cleared when browser closes)
• No data collection, no analytics, no external requests — 100% local
• Optional automation API for Playwright / Puppeteer integration

PRIVACY
MultiLogin Tabs does not collect, transmit, or store any personal data. All session data stays in your browser. No analytics, no tracking, no accounts required.
