A complete cookie toolkit, right in your browser toolbar.
Every cookie for the current site with name, value, domain, path, expiry, and flags. Search and sort by any column.
JWT tokens, Base64, and URL-encoded values decoded automatically. Switch modes manually or let CookiePeek detect the format.
Modify any field through a clean slide-in panel. Add new cookies from scratch with full control over every attribute.
Select multiple cookies and delete them in one click. No more removing cookies one at a time.
JSON, Netscape cookies.txt, Header string, or Profile JSON. Copy to clipboard or save to file in one click.
Paste or upload cookies in JSON or Netscape format. Auto-detection picks the right parser for you.
Follows your system preference or toggle manually. Comfortable viewing in any lighting condition.
No accounts, no analytics, no network requests. Cookie data is read on demand and never persisted or transmitted.
We don't just promise privacy — we enforce it architecturally.
Zero network requests
CookiePeek never phones home. No HTTP calls, no WebSocket connections, no pings.
No analytics or telemetry
No tracking pixels, no usage events, no crash reports. Nothing is measured.
No remote code
Everything runs locally from the extension bundle. No CDN scripts, no external resources.
No data persistence
Cookie data is read on demand and discarded when the popup closes. Only your theme preference is saved.
No accounts required
Install and use immediately. No sign-up, no login, no email required.
