MultiLogin Tabs

Run multiple accounts on the same site in one window. Isolates cookies, localStorage, IndexedDB per tab.

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. Created by Lesnyak
