Our widget uses modern JavaScript (ECMAScript 2021) and WebRTC to deliver video calls, screen sharing, and chat. This article explains exactly which browsers are supported, what features work, and where limitations exist and the WebRTC APIs they rely on.
Minimum Browser Versions
Browsers older than the versions listed below will encounter errors and will not load the widget at all.
| Browser | Minimum Version | WebRTC Audio/Video | Screen Share (getDisplayMedia) |
|---|---|---|---|
| Chrome (desktop) | 85+ | ✅ | ✅ (72+) |
| Edge (Chromium) | 85+ | ✅ | ✅ (79+) |
| Firefox (desktop) | 77+ | ✅ | ✅ (66+) |
| Safari (macOS) | 13.1+ | ✅ (11+) | ✅ (13+) |
| Safari (iOS) | 13.4+ | ✅ (11+) | ❌ |
| Chrome on Android | 85+ | ✅ | ❌ |
✅ = feature works in that browser version range (may rely on webrtc-adapter shims).
❌ = feature not supported natively.
Support Policy:
- Full support (video + audio calls): Chrome/Edge 85+, Firefox 77+, Safari macOS 13.1+, iOS Safari 13.4+
Screen sharing support: Any screen-sharing functionality in an Android or iOS is available only in apps and would need to be implemented using our native SDKs
If you need to support older browsers (e.g., Internet Explorer, very old Chrome), contact support@videoengager.com.
