Hello! We’re delighted that you’re interested in building Dify plugins. This developer documentation center is your core resource, designed to help you learn, create, debug, publish, and manage Dify plugins.

What are Dify Plugins?

You can think of Dify plugins as modular components that give AI applications enhanced perception and execution capabilities. They make it possible to integrate external services, custom functions, and specialized tools into AI applications built with Dify in a “plug-and-play” manner. Through plugins, your AI applications can better “see,” “hear,” “speak,” “draw,” “calculate,” “reason,” connect to external APIs, and even perform real-world actions.

As a plugin developer, you can build exclusive functional extensions for your own Dify applications, or contribute your innovations to the entire Dify ecosystem, benefiting more users.

In this developer documentation, you will find:

This documentation aims to provide clear guidance for plugin developers, whether you’re a first-time experimenter or seeking advanced customization:
