A click-to-call video widget like Halla.live allows customers to start an instant face-to-face call directly from your website without downloading any software or creating an account. It is the lowest friction method to offer high-touch customer support.
Technical Details
Maintaining a lightweight footprint (<50KB) is critical for performance. The widget uses a Shadow DOM to encapsulate styles, ensuring that the host website's CSS does not affect the video UI, and vice versa. This isolation is paired with efficient asset loading and a streamlined WebRTC implementation.
