TL;DR: CookieVault Editor is a privacy-first browser extension from MDL Asia for managing cookies. It offers dual-mode editing (visual and JSON), secure local backup with one-click restore, and import/export for cross-device migration — built for developers, QA engineers, and privacy-conscious power users. Live at cookievault.net/editor.
Cookies sit at the center of web authentication, session state, and testing — yet browsers give you almost no tools to inspect or move them safely. CookieVault Editor fills that gap with a focused, privacy-first approach: your data stays local.
Two editing modes for two kinds of work
CookieVault Editor gives you a visual cookie editor and a JSON bulk editing mode, because cookie work comes in two flavors:
- Visual mode — inspect and tweak individual cookies (name, value, domain, path, expiry, flags) through a clear UI. Ideal for quick fixes and debugging a single session.
- JSON mode — edit many cookies at once as structured text. Ideal for bulk changes, scripted test fixtures, or copying a whole session between environments.
Switching between the two means you can move fluidly from "fix this one flag" to "replace the entire cookie set for this domain."
Backup, restore, and migration
The extension treats your cookie state as something worth protecting:
- Local backup & restore — snapshot your cookies and roll back with one click when a test or login breaks.
- Import / export — move cookie sets in and out as files.
- Cross-device migration — carry a working session from one machine to another without re-authenticating everything by hand.
For QA engineers reproducing a bug on a specific logged-in state, or developers spinning up the same session across devices, this turns a fiddly manual process into a one-click operation.
Privacy first, by design
CookieVault Editor is built around the principle that cookie data should stay with you. Backups are stored locally rather than synced to a third-party server, so you keep control of sensitive session data. That makes it suitable for privacy-conscious power users as well as professional testers handling real credentials.
Who it is for
- Web developers managing sessions across local, staging, and production
- QA engineers reproducing bugs that depend on exact cookie state
- Privacy-conscious users who want visibility and control over what's stored
