 Microsoft Bot Framework:

Microsoft Bot Framework offers an open source chatbot platform for building chatbot softwares. MBF is an initiative backed by Microsoft and its approach is primarily code-driven and aimed solely at developers. It also offers an enormous number of tools to serve the process of chatbot building and the software is built to facilitate integration with Luis, its NLU engine. A disadvantage of the NLU engine is not being open source that it cannot be installed on-prem. This again is obvious from Microsoft as the MBF and Luis are products built-in part to promote the use of its Azure platform. 
Microsoft recently released the composer to make it easier to maintain the Chatbot solution using an interface. Microsoft Bot Framework has two major components Bot Builder SDK and Microsoft Language Understanding Intelligent Service (LUIS). The Boatbuilder is a development SDK that supports .NET and Node.js and is open source chatbot platform and is available on GitHub. Currently, it supports 30 languages and features automated translation.

 Omni-Channel and Multilingual:

Build once and deploy anywhere anytime just you need to make sure that you can connect with users via chatbots. You should look for chatbot development companies that can deploy bots anywhere for websites, mobile apps, Facebook messenger, SMS, etc. You can personalize it according to the platform, good chatbots can interact with even corporate tools like Skype, Slack, etc. But, there is yet another consideration to training the chatbot to interact in multiple languages.
A chatbot with Natural Language Processing and speech support provides authentic interactions using text medium or voice medium. It helps the chatbot to better understand user intent and response with relevant content after proper assessment. The scalability of your chatbot will depend on whether you’ve incorporated Natural Language Processing training or not.


Dialogflow is powered by Google’s machine learning, which can be used to connect to users on Amazon Alexa, Mobile apps, Google Assistant, Slack, Twitter, and more. Dialogflow is a perfect platform to build chatbot solutions for intent-based chatbots. Built text or voice-based conversational interfaces for your bots. Dialogflow uses information like examples, contexts, etc. to match the user questions to a suitable intent. It comes with a training module that tracks user’s requests and shows the administrator how it matched them to the intent then delivers the output as a JSON response object based on the actionable data in the query text. The admin can correct issues if any, and the machine retrains itself accordingly. It comes with a free license and enterprise edition. It currently has SDKs for Android, Xamarin, HTML, JavaScript, iOS, Cordova, Unity, Botkit, Python, Ruby, PHP, etc. Dialogflow is user-friendly, supports 20+ languages, and probably the best framework to develop NLP based applications. One disadvantage with Dialog flow is that it doesn’t allow you to host your instance of your agent thus, it is not secure for some enterprise-level applications.
