AGTA Cookies

Inspect, edit, export and restore cookies. JSON and cookies.txt, session snapshots, undo and locking. All data stays local.

AGTA Cookies is a cookie manager for people who work with cookies every day — web developers, QA engineers, and anyone who needs to test a site as more than one user. WHAT YOU CAN DO See every cookie for the site you're on, or across every site at once. Search by name, value or domain. Tick the ones you care about and the action bar applies to just those instead of everything. Edit any field a cookie has: value, domain, path, expiry, Secure, HttpOnly, SameSite, host-only. Create one from scratch. Delete a single cookie, or everything in scope. SAFETY MOST COOKIE EDITORS SKIP Every delete is reversible. Clearing cookies signs you out of things, so when you do it a toast appears with an Undo button that puts them straight back — for a single cookie or a bulk wipe. Lock the cookies you never want to lose. Bulk delete skips them and tells you how many it protected before it does anything. SESSION SNAPSHOTS Save every cookie for a domain under a name and restore it in one click. Test as an admin, then as a regular user, then as a logged-out visitor, without three browser profiles or logging in again each time. IMPORT AND EXPORT JSON, or Netscape cookies.txt — the format curl, wget and yt-dlp read. Import takes either and works out which it was given, then tells you which domains it is about to write to before it writes anything. Or copy the current selection to your clipboard as JSON without creating a file at all. BUILT FOR REAL COOKIE JARS A thousand-plus cookies render in chunks and the search is debounced, so the popup stays responsive instead of stuttering on every keystroke. All Sites groups by domain with a count for each one. Partitioned (CHIPS) cookies are carried through listing, export and import, so a round trip doesn't quietly drop them. A store picker appears when you have more than one cookie store. You get a warning when a cookie passes the 4KB size limit, and when an expiry goes beyond the 400 days browsers actually honour. PRIVACY No server. No account. No analytics, no telemetry, no remote code. Nothing you do here is sent anywhere. Snapshots and your locked-cookie list live in your browser's own local storage and never sync. There is no donation banner taking up room in the popup. BEFORE YOU USE IT Exported cookie files contain live session credentials. Anyone who has one can sign in as you until those sessions expire. Treat them like passwords: don't email them, don't commit them to a repository, and don't import files from people you don't trust. Use AGTA Cookies on accounts and sites that are yours, or that you are authorised to test.
