OpenCookie — Local Cookie Editor

About

OpenCookie is a trustworthy, local-only cookie editor for Manifest V3. View, edit, add, delete, search, and import/export cookies for the current tab — with zero data upload. Everything stays inside your browser.

WHY OPENCOOKIE
• Local-only by design. There is no server, no analytics, no tracking, no account. Your cookies never leave your machine.
• Open source and auditable. The full source is on GitHub — read exactly what it does.
• Minimal permissions. Nothing scary at install: the extension asks for site access only when you grant it, per-site or for all sites, from inside the popup.

FEATURES
• View all cookies for the current tab, with full attributes.
• Add, edit, and delete individual cookies.
• Delete all cookies on the page, with a confirmation step.
• One-click copy of a cookie's value.
• Live search and filter by name or value.
• Import / export cookies as JSON — compatible with common cookie tools — via
    copy, paste, or file.
• Light / dark theme, remembered across sessions.

PRIVACY
No data ever leaves your browser. No remote server, no analytics, no advertising, no third-party sharing. Local storage is used only to remember your light/dark theme preference. Full privacy policy:
