Open Source Tools and Libraries to Customize and Extend Chatbot Technology

Chatbot technology is becoming increasingly popular as businesses look for ways to provide better customer service and optimize their operations. Fortunately, there are a number of open source tools and libraries available that can help developers customize and extend the capabilities and features of chatbot technology. For example, Nykaa, one of the largest e-commerce companies in India, used a state-of-the-art platform to create a customer service chatbot that provides a better and more efficient service to its customers. On the other hand, a company like Adobe is the best example of how a company uses an open source platform such as Microsoft Bot Framework (MBF) to optimize its chatbots.

In fact, more than 41% of the companies included in the Mindbowser study preferred MBF to industry alternatives. SMS, Slack, Email, Office 365, Twitter and Telegram are just a few of the many platforms that MBF covers. The Bot Builder SDK is compatible with . NET and Node.js. In addition to having an automatic translation function, LUIS offers support for more than 30 languages.

You can use LUIS to understand natural language, Cortana for voicebot, and the Bing APIs to search.

Rasa Stack has two important components that are independent of each other: a “core” and an “NLU”. It's one of the only production-ready platforms that offer flexible, natural conversations that scale.
