CookieMate — Cookie Editor, Inspector & Manager, EditThisCookie Alt

About

Cookie editor and inspector built for developers. View every cookie on the current site, edit any attribute inline (name, value, domain, path, expiration, Secure, HttpOnly, SameSite), bulk delete, and export full sessions to JSON in one click. A modern, MV3-native cookie editor and a drop-in replacement for EditThisCookie — open source, no telemetry, no ads.

EditThisCookie was removed from the Chrome Web Store in late 2024 after Manifest V2 was deprecated, and the clones that took its place have a history of malware reports. CookieMate is the cookie editor that fills the gap: same workflow, same JSON format, but on Manifest V3 and built to last.

WHAT YOU CAN DO

• View — every cookie for the active tab, sorted and searchable by name, value, or domain
• Edit — change name, value, domain, path, expiration, Secure, HttpOnly, SameSite inline
• Add — create new cookies manually to test auth flows
• Delete — bulk-select and remove, or wipe all cookies for the current site
• Export — save the whole session as JSON in the EditThisCookie-compatible format
• Import — drop any EditThisCookie or CookieMate JSON backup back in
• Theme — light, dark, or follow the system
• Badge — optional cookie count on the toolbar icon

USE CASES

• Web developers debugging login, session, and auth flows
• QA engineers reproducing bug reports tied to specific session state
• Selenium and Playwright users preparing cookie fixtures for tests
• Security researchers inspecting tracking cookies and third-party flags
• Switching between staging and production sessions without clearing the whole browser
• Editing HttpOnly cookies that the DevTools panel will not let you touch
• Toggling Secure and SameSite flags to reproduce CSRF and CORS edge cases

WHY COOKIEMATE

• MV3-native cookie editor — built on Manifest V3, will not be pulled like EditThisCookie was
• Licensed under MIT — clean, minimal codebase
• No telemetry, no tracking, no third-party scripts — your cookies stay on your machine
• No account, no signup, free forever
• EditThisCookie-compatible JSON — your old backups load without conversion
• Minimal footprint — fast popup, instant cookie list, no bloat

MIGRATING FROM EDITTHISCOOKIE

1. If the old EditThisCookie still works for you, open it → Options → Export → download the JSON file
2. Install CookieMate and open Settings
3. Drop the JSON file in the Import section — every cookie comes back with its domain, path, and flags intact

If EditThisCookie is already gone and you have an old backup lying around, CookieMate will read it as-is.

LOOKING FOR AN ALTERNATIVE TO...

EditThisCookie, Cookie-Editor, Cookie Manager Pro, EditThisCookie (V3), J2TEAM Cookies, Cookie Quick Manager, Cookiebro, Cookie Editor and Storage Manager — CookieMate is the lightweight, open-source, MV3-native cookie editor built specifically as a drop-in replacement.

PERMISSIONS — AND WHY

• cookies — the whole reason this extension exists: read, write, and delete cookies
• activeTab, tabs — identify which site you are currently looking at
• storage — save your theme and badge preference locally
• host permissions (<all_urls>) — required by chrome.cookies for any visited domain. CookieMate does NOT read page content, does NOT inject scripts, and only calls chrome.cookies.*.

PRIVACY

Nothing leaves your browser. No telemetry. No analytics. No remote calls. The extension never opens a network connection of its own.
