CookieMan

CookieMan is a cookie editor for Chrome: open the popup and every cookie for the site you are on is right there, live, with the flags that matter visible without expanding a single row. WHAT YOU CAN DO • See every cookie for the current site, updated the moment the browser writes, replaces or deletes one. The toolbar badge keeps the count in view. • Search by name, value or domain as you type. • Edit any attribute: name, value, domain, path, expiration, Secure, HttpOnly, SameSite, host-only, and the partition key for partitioned (CHIPS) cookies. • Add a cookie from scratch, delete a single one, or clear every cookie for the current domain when you need a clean session. • Import by pasting anything: JSON array, JSON map, Netscape cookies.txt, a Cookie: request header, Set-Cookie lines, or Base64-encoded JSON. The format is detected for you and previewed before it is applied. • Export the current site or every accessible cookie in any of those six formats, then copy it or download a file. WHY IT IS DIFFERENT • Manifest V3. Built on the current extension platform, so it is not affected by Chrome's Manifest V2 shutdown. If you used EditThisCookie, your old JSON exports import here unchanged. • Nothing leaves your machine. The extension contains no network code at all — no fetch, no analytics, no telemetry, no remote configuration. Cookie values are read through the browser API, shown in the popup, and forgotten when it closes. • The only thing stored is your theme and language choice. • Free, open source, MIT licensed, no account, no paid tier. HTTPONLY COOKIES Because CookieMan uses the browser cookies API rather than page JavaScript, it reads and edits HttpOnly cookies too — the ones a page's own scripts cannot see. FOR DEVELOPERS AND QA Expire a session by hand instead of waiting an hour. Flip an A/B variant cookie and reload. Move a logged-in session into curl, Playwright or another profile in the format that tool expects. Check whether a third-party cookie is partitioned or simply blocked. A note on safety: an exported session cookie is a credential. Keep exports out of shared documents and delete them when you are done. Interface in English and Russian. Works in Chrome, Edge and other Chromium browsers with Manifest V3 support. Documentation: https://cookieman.pro/docs/ Free online cookie converter: https://cookieman.pro/tool/
