Inspecting Cookies
Open Cookie Lens as a popup or DevTools panel and explore browser cookies — search, filter, scope, sort, and pin them on any site.
Editing Cookies
Edit cookie values and attributes (domain, path, expiry, Secure, HttpOnly, SameSite) safely from the Cookie Lens popup or DevTools panel.
Parsing & Decoding Values
Decode and edit JWT, JSON, Base64, URL-encoded, and delimited key/value cookie values directly inside Cookie Lens.
Freezing Cookies
Freeze a cookie to pin its value — a background enforcer instantly reverts any page or server change, or deletion, until you unfreeze it.
Mocking Cookies
Test your app with mock cookie values without losing the original — useful for auth states, feature flags, and edge cases.
Profiles
Save named cookie sets and switch between scenarios — logged-in, guest, admin — in one click. Export and import profiles as a file, scoped to the current site.
Reports & Analysis
Run the Cookie Lens Report to score every cookie and surface severity-ranked security, privacy, size, and expiry findings — with fixes and trends.
Set by Request
See which network request set or updated each cookie — method, URL, timestamp, and the response Set-Cookie headers — right inside the Cookie Lens editor.
Using the side panel
Keep the full Cookie Lens beside the page — a persistent side panel that follows the active tab, stays live as cookies change, and opens or closes from the popup.
