What is Free Chat SDK & API Software?

Chat SDK and API providers offer tools and services that enable developers to integrate real-time chat functionality into applications. These solutions typically provide pre-built components like chat interfaces, messaging systems, and notifications, reducing the need for custom development. Providers often offer APIs that allow seamless interaction with chat services, such as sending and receiving messages, managing user profiles, and customizing chat experiences. SDKs, on the other hand, often come with libraries and documentation to help developers quickly build and deploy chat features on mobile or web platforms. Some popular chat SDK & API providers also include advanced features like video calling, chatbots, and analytics for enhanced communication experiences.
