Cookie & LocalStorage Editor by HomieLab

Quick edit cookies and localStorage of the current site: view, add, delete, import and export as JSON. No tracking.

Cookie & LocalStorage Editor by HomieLab is a fast, private way to quick edit the cookies and localStorage of the page you are on: view, add, edit, delete, import and export them without leaving the tab. Two tabs, one click apart. It shows every cookie the browser would send to the current tab — cookies set on parent domains, HttpOnly cookies the page itself cannot read — and lets you create, change or remove any of them in a couple of clicks. Works in Chrome, Edge, Brave and Opera. BUILT FOR DEVELOPING Set a cookie to test a feature branch. Change one value and reload. Clear the cookies a site left behind when you want the page to behave as if it had never met you. No console incantations, no reloading between attempts. BUILT FOR PRIVACY See what a site has stored about you, then decide what stays. "Delete all" clears a site in one step, behind a confirmation. EVERY ATTRIBUTE, IN ONE EDITOR Value, domain, path, expiry, SameSite, Secure, HttpOnly and Partitioned (CHIPS). Expiry presets cover the usual cases and a precise date covers the rest. Duplicate a cookie to try a second value side by side. LOCAL STORAGE, TOO The Local storage tab lists the page's localStorage with each item's size. Click an item to edit its value straight away, format JSON values to read them, rename keys, and save with Ctrl + Enter. Writes are all or nothing: if the site's storage is full, nothing is half-written. IMPORT AND EXPORT Export cookies as lossless JSON, or as a Cookie header string you can paste into a request or a test fixture, and local storage as a JSON object. Import them back. A paste with one unreadable cookie is refused as a whole, and cookies for other domains are never written. KEYBOARD FIRST 1 / 2 Cookies / Local storage / filter the list N new cookie or item E / I export / import Ctrl + Enter save Esc close PRIVATE BY DESIGN No background process, no network access, no analytics, no telemetry. Nothing you see or edit ever leaves your computer. Installing it grants no access to any website: the first time you open it on a site, it asks for that site only, or all sites if you prefer, and you can take access back at any time.
