JarFlip – Cookie Editor & Multi-Account Switcher

Cookie editor with one-click account switching. Save logins as jars, edit & export cookies. No ads, no tracking, no network access.

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.
