CookieJar

A friendly cookie manager for developers.

See, search, edit, protect and export cookies across every domain in the browser — for the days you're debugging an auth flow and the cookie that matters belongs to someone else's domain.

Put it in your toolbar

The whole jar

A popup for the current site (including parent-domain and sibling-subdomain cookies) and a full-tab manager for everything, grouped by domain withdomain: and name: search prefixes.

Edit without landmines

A drawer editor that live-validates the tricky rules — __Host-and __Secure- prefixes, SameSite=None ⇒ Secure, host-only versus domain cookies — before Chrome silently rejects your edit.

Protect & pin

Shield the cookies you can't afford to lose — bulk deletes skip them and report "2 protected kept". Pin your important domains (your auth0 tenant, say) to the top of the list.

Plays nice with your terminal

Export JSON, CSV, or Netscape cookies.txt that feeds straight into curl -b, wget and yt-dlp. Copy a ready Cookie header or a complete cURL command per domain. Imports EditThisCookie and Cookie Editor files as-is.

X-ray for tokens

JWTs get a badge and an inline decoded panel — claims, expiry countdown, expired highlighting — even URL-encoded or wrapped in JSON. The timeline records every cookie change; snapshot before a login, diff after, and see exactly what your flow touched.

"Explain this cookie"

Ask what a cookie is for, answered by Chrome's on-device AI (or the Claude API with your own key). Privacy-first: only metadata is sent — never the value. Length, format, JWT claim names, timing; the content stays in your browser.

Also in the jar

Install it

Not on the Chrome Web Store (yet) — you load it straight from the source, which also means you can read every line of what runs.

  1. Clone and build:
    git clone https://github.com/pearpages/orchard
cd orchard
pnpm install
pnpm --filter @cookiejar/extension build
  2. Open chrome://extensions and enable Developer mode.
  3. Click Load unpacked and pick theplugins/cookiejar/extension/dist folder.
