Plugins are external modules that add functionality to PyMOL.

Plugins can be single Python files (*.py) or directories with an __init__.py file (see PluginArchitecture).

Looking for available Plugins? Browse the plugins category.

Installing Plugins

To install a plugin, open PyMOL and then go to

Plugin > Plugin Manager > Install new plugin

You will have the option to install from a file on your computer (*.py, *.zip) or directly from the PyMOLWiki by providing the wiki page url.

Legacy Notes

Before Version 2.0

Plugins written with PyQt5 do not run in PyMOL 1.x.

PyMOL 2.x has a legacy layer for Tkinter to support old plugins, but the preferred toolkit for new plguins is PyQt5.

Before Version 1.5.0.6

Before PyMOL's Plugin Manager was added in version 1.5.0.6, plugins could not be installed per user, the plugin search path was a single directory inside the PyMOL installation: $PYMOL_PATH/modules/pmg_tk/startup

Plugins were limited to single Python files, directories were not supported yet.

MacPyMOL

MacPyMOL was the native macOS version of PyMOL before version 2.0. It supported Plugins only in the X11 Hybrid mode.
