localStorage is a web browser API that allows websites to store key-value pairs locally in the user's browser. Data persists even after the browser is closed and can be accessed by JavaScript on the same domain.
The tool automatically loads and displays all localStorage items for the current domain. You can see all keys and values, edit them, add new items, or delete existing ones directly from the interface.
Yes! Click the edit icon next to any item to modify its value. You can also add new items using the 'Add Item' form and delete items using the trash icon. Changes are saved immediately to localStorage.
localStorage is domain-specific, meaning data is only accessible by JavaScript from the same domain. However, it's not encrypted and can be accessed by any script on the domain, so don't store sensitive information like passwords.
Yes! Our localStorage viewer is 100% free with no registration required, no usage limits, and no hidden fees. You can view and manage localStorage as much as you need for your development work.
No, all localStorage viewing and editing happens locally in your browser. We don't store, save, or have access to any localStorage data. Your privacy is completely protected.
Most browsers allow 5-10MB of localStorage per domain. The exact limit varies by browser. If you exceed the limit, setting new items will fail with a QuotaExceededError.
localStorage only stores strings. To store objects, use JSON.stringify() to convert them to strings, and JSON.parse() to retrieve them. The tool displays values as strings, so you'll need to parse JSON manually if needed.
Click the 'Refresh' button to reload all localStorage items. The tool also automatically refreshes when storage events occur (when localStorage is modified in other tabs).
Clearing localStorage removes all items for the current domain. This action cannot be undone. Make sure to copy any important data before clearing if you need it later.
Yes! The tool works on any website. It displays localStorage items for the current domain you're visiting. Each domain has its own separate localStorage, so you'll only see items for the current site.
