However, not all chatbot frameworks and platforms are created equal. They have different strengths and weaknesses, advantages and disadvantages, and suitability and compatibility for different chatbot projects. Therefore, choosing the right chatbot framework and platform is a crucial step in your chatbot development process. You need to consider various factors, such as your chatbot’s purpose, functionality, language, platform, and audience, as well as your own skills, preferences, and budget.
