Debugging storage shouldn't slow you down
Manually clearing Local storage to test different states. Editing cookies one by one to switch accounts. Copying storage values to decode JWTs on external sites.
It's tedious work that interrupts your flow. StorageKit eliminates the friction so you can focus on building.
Features
Everything you need to debug storage
A complete toolkit for inspecting, managing, and debugging browser storage, built right into your DevTools.
Live Inspector
View and edit Local storage, Session storage, and Cookies in real time. Changes reflect instantly on the page.
Snapshots
Save the current storage state with one click. Restore it later to instantly reproduce any application state.
Cross-Domain Snapshots
View snapshots from all domains in one place, or filter by the current site for focused debugging.
Value Decoding
Automatically detects and decodes JSON, Base64, JWT, and URL-encoded values. JWT metadata shows expiry and algorithm.
Import & Export
Backup your snapshots as JSON files. Share storage configurations with your team for consistent debugging.
Privacy First
All data stays in your browser. No analytics, no tracking, no external servers. Your storage data never leaves your machine.
In Action
See it in action
Live Storage Inspector
Browse all your storage data in a clean, organized interface. Edit values inline, search across keys, and see changes reflected instantly.
Save & Restore States
Capture your entire storage state (Local storage, Session storage, and Cookies) in a single snapshot. Restore it anytime to recreate that exact state.
Automatic Value Decoding
StorageKit automatically detects encoded values and shows them decoded. JSON is pretty-printed, JWTs reveal their payload, and Base64 values are decoded inline.

Use Cases
Built for real debugging workflows
Switch between user roles
Save a snapshot for each user role (admin, editor, viewer). Switch between them instantly without logging out and back in.
Reproduce bugs reliably
Capture the exact storage state when a bug occurs. Share the snapshot with your team so anyone can reproduce it in one click.
Share configurations
Export storage snapshots as JSON files. Onboard new team members by sharing the exact storage setup they need.
Debug tokens without leaving the browser
Inspect JWT payloads, check expiry dates, and view decoded Base64 values without switching to external tools.
FAQ
Frequently asked questions
Yes, StorageKit is completely free to use. There are no premium tiers, no feature limits, and no hidden costs.
StorageKit is currently available for Chrome and all Chromium-based browsers (Edge, Brave, Arc, Opera, etc.).
No. All data stays entirely in your browser. StorageKit has no analytics, no tracking, and makes no network requests. Your storage data never leaves your machine.
Snapshots are stored using Chrome's built-in extension storage API, which persists across browser sessions. You can also export them as JSON files for backup.
StorageKit works on any regular website. It cannot access restricted pages like chrome:// URLs, the Chrome Web Store, or other extension pages due to browser security policies.
Not yet. StorageKit is currently Chrome-only, but support for other browsers may be added in the future.
