LocalStorage Inspector – View and Manage Browser Storage
LocalStorage is a powerful browser API that allows web applications to store data locally in the user's browser. It persists between sessions and provides up to 5-10MB of storage per domain. However, inspecting and managing localStorage data can be tedious using browser DevTools alone. The LocalStorage Inspector by ToolfolioHub provides a user-friendly interface to view all localStorage keys and values, delete individual items, or clear all data at once.
Whether you're debugging web applications, resetting tool data, or understanding what data is stored by websites, this inspector makes localStorage management easy.
What is LocalStorage?
LocalStorage is a web storage API that:
- Persists Data: Data remains after closing the browser
- Domain-Specific: Each website has its own storage (5-10MB limit)
- String Storage: Stores key-value pairs as strings
- No Expiration: Data persists until explicitly deleted
Unlike sessionStorage (cleared on tab close), localStorage data persists indefinitely until removed.
Key Features
1. View All Items
See all localStorage keys and values in a clean, organized list. JSON values are automatically formatted for readability.
2. JSON Detection
Automatically detects and formats JSON values, making complex data structures easy to read.
3. Individual Item Deletion
Delete specific items without clearing everything. Perfect for removing outdated data while keeping other entries.
4. Clear All Functionality
One-click option to clear all localStorage data for the current domain. Includes confirmation dialog to prevent accidents.
5. Auto-Refresh
Automatically refreshes every 2 seconds to show changes in real-time as other tools or scripts modify localStorage.
Common Use-Cases
- Debugging: Inspect what data tools or applications are storing
- Resetting Tools: Clear data to start fresh with tools that use localStorage
- Privacy: Remove stored data from websites
- Development: Test applications with clean storage states
When to Clear LocalStorage
- Tools aren't working correctly due to corrupted data
- You want to reset a tool to its default state
- Privacy concerns about stored data
- Testing applications with empty storage
Conclusion
The LocalStorage Inspector simplifies managing browser storage with a clean interface and powerful features. It's essential for developers debugging applications and users managing tool data.
