Cookie Cockpit

Cookies shape your online experience in ways you might not realize. They are simple text files stored on your device. They persist information, e.g. device IDs, across sessions. This can be used to control login sessions, ensure site functionalities, store personal preferences, and maintain device identification for returning visitors. Understanding which cookies are active — and who set them — helps you protect your privacy, debug website issues, verify compliance with regulations like GDPR, and make informed decisions about the services you use.

No. Cookie Cockpit processes everything locally in your browser. No data is collected, stored, or sent to any external server. There are no analytics, no tracking, and no third-party services. Your browsing data stays entirely on your machine.

Cookie Cockpit is built for Google Chrome using Manifest V3 and requires Chrome 116 or later. It works on any Chromium-based browser that supports Chrome extensions, including Microsoft Edge, Brave, Arc, and Opera.

Cookie Cockpit maintains an internal database of known cookie patterns from advertising networks, analytics providers, consent management platforms, and other third-party services. When it detects a cookie, it matches the cookie name and domain against this database to identify the vendor and purpose behind it.

Cookie Cockpit is a free, open-source cookie manager for Chrome and Chromium-browsers that combines a live dashboard, real-time monitoring, vendor identification, local storage inspection, and full cookie editing in a single extension. It is privacy-first with zero data collection and is MIT-licensed. While there is no definite universal answer to what the best extension is, Cookie Cockpit is a state-of-the-art and modern all-in-one cookie solutions that is likely to match your exact needs.

Cookie Cockpit automatically identifies cookies from known ad networks, analytics providers, and consent management platforms using a built-in vendor database. It color-codes third-party cookies in blue and shows the vendor name and purpose for each recognized cookie.

Cookie Cockpit shows you every cookie set by the website you are currently visiting as soon as you open the extension. Click on any cookie to open the detail view, then modify its value, expiration date, domain, path, or security flags. Changes take effect immediately — no browser restart needed. You can also create new cookies with custom attributes, delete any individual cookie with one click, or use the bulk delete option to clear all cookies for that site at once. The live view updates in real time, so you can immediately confirm your changes.

Yes. Cookie Cockpit is the only cookie manager extension that automatically cross-references every cookie value with the site's Local Storage entries. If a match is found, it's flagged with an orange "Found in Local Storage" badge on the cookie card and highlighted in a dedicated counter on the dashboard.

Cookie Cockpit maps IDs found in cookies with IDs found in Local Storage, in order to help you identify if sites duplicate specific IDs across browser device storage methods. This allows you to single out redundant or persistent tracking identifiers that survive cookie deletion by being duplicated to Local Storage. While this technique is not inherently harmful and can be useful for site functionality, there are numerous cases in which redundant tracking IDs by tracking- or ad-vendors are using this method to persist their user identification despite a user clearing their cookies. Cookie Cockpit gives you an additional layer of control and allows to delete redundant Local Storage entries right from the dashboard.
