Keinepad - Cookie & Cache Editor

View, edit and clear cookies, storage and caches of the current site.

Keinepad is a cookie and site data editor for the page you are on. Open it from the toolbar or the side panel to see everything the current site has stored in your browser, change it, or wipe it clean in one click. It is made for web developers, testers and anyone who is tired of "did the cache really clear?". COOKIES • All cookies of the current site, including parent domains and subdomains • HttpOnly and partitioned (CHIPS) cookies are shown too • See which cookies are sent with the current URL, or filter to only those • Add, edit, delete and bulk-delete cookies; edit name, value, domain, path, expiry, Secure, HttpOnly, SameSite and Partitioned • Validation before saving: SameSite=None requires Secure, __Host- / __Secure- prefix rules, and more • Value preview: URL decoding, JSON formatting, JWT decoding with expiry time • Copy as a Cookie: request header, export and import JSON (compatible with common cookie editor formats) • The list refreshes live when cookies change LOCAL STORAGE / SESSION STORAGE • Browse, search, add, edit (format or minify JSON), delete, clear and export key–value pairs CACHES AND DATABASES • IndexedDB: databases, versions, object stores and record counts; delete databases • Cache Storage: caches and the request URLs inside them; delete entries or whole caches • Service Workers: registrations and their state; unregister • HTTP cache: clear it for the current origin, or hard-reload the page CLEAR SITE DATA IN ONE CLICK Pick which data types to clear (cookies, Local Storage, Session Storage, IndexedDB, Cache Storage, Service Workers, HTTP cache) and optionally reload the page afterwards. FIX GARBLED PAGES Right-click a page → "Page encoding", or use the dropdown in the popup, to reload it with another character encoding: UTF-8, UTF-16, GBK / GB2312, GB18030, Big5, Shift_JIS, EUC-JP, ISO-2022-JP, EUC-KR, Windows-125x, ISO-8859-x, KOI8-R and more. The choice applies to the current site in the current tab. EXPORT YOUR WAY Every export can be copied to the clipboard or saved as a file. COMFORTABLE TO USE • Toolbar popup and side panel (the side panel follows the active tab) • Light and dark theme follow your system • Interface in English, 简体中文 and 日本語 PRIVACY Keinepad works entirely inside your browser.
