Why Check Storage Capacity Limits in Your Web Browser?

Modern web applications (like progressive web apps, offline databases, and local file editors) store files directly inside your browser cache. If the browser runs out of allocated cache space, offline features will break and stored files can be deleted automatically. Checking your browser storage limits helps you verify how much data you can safely cache. Our browser-native Storage Capacity Viewer calculates these limits locally on your machine. Check your storage limits at /devicelab/device-info/storage-capacity-viewer.

Understanding Browser Storage APIs: Quota and Usage

Browsers allocate storage cache quotas based on your system's total hard drive size (typically up to 50% of free space). The StorageManager API allows scripts to query the total allowed storage space (Quota) and the space currently consumed (Usage), helping developers optimize local data storage.

How to View Caching Space and Disk Limits Locally

Go to /devicelab/device-info/storage-capacity-viewer. The utility queries the StorageManager, displaying your storage quota, current usage, and percentage of cache space remaining, ensuring no private file directory metadata is shared online.
