Cache Clear

About

Cache Clear is a developer-focused browser extension that gives you full visibility and control over every storage mechanism on any webpage — all from a clean, fast popup.
Inspect everything in one place.

Open the popup on any tab to instantly see all stored data: localStorage and sessionStorage key-value pairs, cookies with their flags (HttpOnly, Secure, SameSite), IndexedDB databases and object stores, Cache Storage entries, registered Service Workers, and HTTP cache usage.
Clear only what you want Select individual storage types using checkboxes and clear them with a single click. No more opening DevTools, navigating multiple panels, and manually deleting entries one by one.

Pin items to protect them

Pin any key, cookie, cache, or service worker scope to keep it safe during a clear. Pinned items are never removed — even if you select all storage types and clear everything else. Pins persist across sessions, per origin.

100% local — no data leaves your device


Cache Clear never transmits, collects, or stores any browsing data remotely. All storage inspection and clearing happens on-device. Pin preferences are saved locally in extension storage, scoped per origin.
