CrumbJar

Offline cookie manager: view, edit, add, delete, and export cookies for the current site. No network access, no telemetry.

CrumbJar is a completely offline cookie manager for your browser. View, edit, add, delete, and copy cookies for the site you're on — without opening dev tools every time. WHY CRUMBJAR Most cookie-editing extensions request broad permissions and run code you can't inspect. CrumbJar makes zero network requests, has no background scripts, and no analytics. Every action goes through the browser's own cookies API, scoped to the site you're viewing. The full source is open on GitHub. FEATURES • View all cookies for the current site (including parent domains) • Search and filter by name or value • Add, edit, and delete cookies with built-in validation • One-click copy of any cookie's value • Mark cookies as protected so bulk delete skips them (e.g. your login session) • Bulk delete all unprotected cookies for the current site • Export cookies to JSON and import them back — handy for backups or moving sessions between profiles • Light, dark, and system theme PRIVACY CrumbJar collects nothing and sends nothing anywhere.
