BotMan

BotMan is a free PHP framework for developing chatbots. It is one of the most popular open-source PHP chatbot frameworks in the world. BotMan is designed for developers to simplify the task of creating innovative bots for multiple messaging platforms, including Slack, Telegram, the Microsoft Bot Framework, Nexmo, HipChat, Facebook Messenger, and WeChat.

BotMan allows you to write your chatbot logic once and connect it to various messaging services, including Amazon Alexa, Facebook Messenger, Slack, Telegram, or even your own website.

BotMan is framework-agnostic, meaning you can use it within your existing codebase with any framework you prefer. BotMan focuses on providing an expressive yet powerful syntax that allows you to concentrate on business logic rather than framework code.

BotMan offers comprehensive documentation and is written in PHP, working on Linux, Windows, and macOS. BotMan is licensed under the MIT License.
