Yes, IndexedDB is supported in all modern browsers, but there are some differences and limitations in older versions or private modes.

Current Browser Support (2025)

Browser IndexedDB Support
Chrome (all versions since 11) Full support
Firefox (since v4) Full support
Safari (since v10.1) Full support, quirks exist
Edge (Chromium & Legacy) Full support
Opera Full support
Android WebView Yes
iOS Safari Yes, but limited before v13
Internet Explorer 10–11 Basic support, many limitations

Older Version Caveats

IE 10 & 11

IndexedDB is supported, but:

  • Only basic features
  • No support for Blob storage
  • Less stable; crashes more frequently
  • Poor error reporting

Safari (before v13)

Quirky behavior:

  • Private mode breaks IndexedDB
  • indexedDB.open() may silently fail or throw QuotaExceededError
  • Data loss across sessions
  • Always wrap logic in feature detection (see below).

Private/Incognito Mode Limitations

Browser Behavior in Private Mode
Chrome ✅ Works normally
Firefox ✅ Works normally
Safari ⚠️ IndexedDB often disabled or fails silently
Edge ✅ Works normally

Feature Detection (Recommended Practice)

Before using IndexedDB, always check support:

if (!window.indexedDB) {
    alert("Your browser doesn't support a stable version of IndexedDB.");
} else {
    // Safe to proceed
}

Tips for Legacy Support

Strategy Benefit
Use window.indexedDB check Avoid crashes or unsupported errors
Use Promises or wrappers Simplifies async error handling
Use localForage A fallback wrapper that uses IndexedDB, WebSQL, or localStorage depending on support

Summary

Environment Support Notes
Modern browsers Full Chrome, Firefox, Edge, etc.
iOS Safari < 13 Partial Beware of private mode & quota issues
IE 10/11 Limited Avoid for serious apps
Incognito mode Varies Safari blocks; Chrome/Firefox OK
