Cookie & LocalStorage Editor by HomieLab by HomieLab

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.
