pluggy is a minimalist, production-ready plugin system for Python, providing hook specification and implementation mechanisms. It is the core framework powering pytest, tox, and devpi.

Use cases

• add a plugin architecture to my python application
• let users extend my tool with custom hooks
• define hook specifications and implementations in python
• build an extensible framework like pytest
• call multiple plugin implementations of the same hook
• manage plugin registration and hook calls

When to choose

• you need a battle-tested plugin/hook system for a Python project
• you want lightweight hookspec/hookimpl semantics without heavy dependencies
• you're building tooling in the pytest/tox ecosystem

When to avoid

• you need plugin discovery across process or language boundaries
• you want a full event bus or async-first plugin framework
• your project is not in Python
