# Chat widget browser requirements

The chat widget now supports Chrome 99, Edge 99, Firefox 97, and Safari 15.4 as its minimum desktop browser versions. On iOS, the minimum supported version is iOS 15.4 for Safari and in-app WebViews. On Android, the minimum supported version is 99 for Android System WebView or Chrome.

The chat widget runs in the device's web engine. Android System WebView updates separately from the operating system through the Play Store.
