Difference between Web widget and Mobile SDK

***	Web widget	Mobile SDK
Destination	Hosted on Website	Hosted on Mobile app
Entry point	Supports both floating bot icon and custom entry point	Supports only custom entry point
Hardware permission	The bot will inherit the same permissions as the browser	Need to define mic, location, storage, and other hardware permissions in the SDK
Optimisation	Better optimized for web browsers	Better optimized for mobile screens and keyboards, with native attachment button support.
Push notifications	Supports browser push notifications which require additional setup (service worker)	Supports Firebase push notifications even without the need of device token. Additionally, you can also configure sendIOSEvent to redirect users to any other screen within or outside the app

Customisation	Supports custom script to override bot’s UI elements	Supports custom loader (while loading chatbot)
Speech-to-text (STT) & Text-to-speech (TTS)	Supports both	Not supported Note: STT is not optimised for Mobile but mobile keypads support STT
