Build Status Coverage Package version Join the chat at


FastAPI framework plugins - simple way to share fastapi code and utilities across applications.

The concept is plugin - plug a functional utility into your application without or with minimal effort.


See release notes


pip install fastapi-plugins
pip install fastapi-plugins[memcached]
pip install fastapi-plugins[all]

Quick start


Add information about plugin system.

Application settings

Add information about settings.

Application configuration
