CookiePeek troch 301.st

CookiePeek is a privacy-first cookie manager for developers, QA engineers, and anyone who needs full control over site cookies.

One click on the toolbar icon opens a complete cookie table for the current site — search, sort, select, edit, decode, export. No extra tabs, no clutter, no waiting.

FEATURES

• Instant cookie table — see every cookie for the current page with name, value, domain, path, expiry, and flags. Search and sort by any column.

• Inline decode — JWT tokens, Base64, and URL-encoded values are decoded automatically. Switch modes manually or let CookiePeek detect the format.

• Edit & add cookies — modify any field (name, value, domain, path, expiry, Secure, HttpOnly, SameSite) through a clean slide-in panel. Add new cookies from scratch.

• Bulk operations — select multiple cookies with checkboxes and delete them in one click.

• Export formats — JSON, Netscape cookies.txt, Header string, and Profile JSON (multi-profile compatible).

• Import — paste or upload cookies in JSON or Netscape format. CookiePeek auto-detects the format.

• Dark & light theme — follows your system preference or toggle manually.

PRIVACY

CookiePeek makes zero network requests. No analytics, no telemetry, no remote code. Everything runs locally in your browser. Cookie data is read on demand and never persisted to extension storage.

PERMISSIONS

• "Access your data for all websites" — required to access cookies via the browser cookies API. CookiePeek does not inject scripts or modify page content.

• Theme preference is stored locally. Cookie data is never persisted.
