JarFlip – Cookie Editor & Multi-Account Switcher

JarFlip lets you switch between test accounts in one click and edit browser cookies without leaving the page. Sign in once as each user, save the login as a "jar", and flip between Admin, Free and Paid accounts without logging out. If a flip fails halfway, everything is rolled back so you are never left half signed in, and Undo stays available for 10 seconds. SWITCH ACCOUNTS • Save a site's sign-in as a named, colored profile • Flip to any saved profile in one click; the tab reloads as that user • See at a glance which profiles are fresh, about to expire or already expired • Get a warning when a site ties sessions to the device and may ask you to sign in again EDIT COOKIES • Add, edit and delete entries: value, domain, path, expiry, Secure, HttpOnly and SameSite • Partitioned (CHIPS) data is shown and saved with its top-level site • Plain-language errors when the browser would reject a change, such as __Host- and __Secure- prefix rules • Search by name, value or domain, and decode JWT values to read their claims • Use it from the popup, the browser side panel or a DevTools tab SHARE AND REUSE • Bring in files exported from other tools; the format is detected automatically and previewed before anything is written • Export for scripts, command-line tools and test suites, or copy a ready-made header • Hand a teammate an encrypted file protected by a passphrase, with no server involved COMPARE AND CHECK • Diff your browser against any saved profile before you flip • Audit a site for missing HttpOnly or Secure flags, loose SameSite settings and oversized or very long-lived entries, then copy the report as Markdown PRIVACY • The extension cannot make network requests, so nothing can be sent anywhere • No accounts, ads, analytics or tracking • No website access at install: JarFlip asks for one site at a time, and you can revoke each one from the dashboard • Saved profiles stay on your device and are not encrypted at rest, so treat exported files like passwords Press Alt+J to open JarFlip from the keyboard.
