Finding and installing plugins

napari plugins are Python packages distributed on the Python Package Index (PyPI), and annotated with the tag Framework :: napari. The napari hub uses this data, together with additional metadata, to produce a more user friendly way to find napari plugins.

Similarly, plugins annotated on PyPI with Framework :: napari are listed in the Plugins > Install/Uninstall Plugins menu within napari.

Installing plugins with napari

All PyPI packages annotated with the Framework :: napari tag can be installed directly from within napari: Firstly, from the “Plugins” menu, select “Install/Uninstall Plugins…”. Then, in the plugin installer menu that opens, you can either:

napari viewer's Plugins menu with Install/Uninstall Plugins as the first item.

  1. Install plugins from the list: you can scroll through the list of “Available Plugins”, or filter plugins using the text box at the top of the dialog. From the list, you can then install a plugin by clicking the install button in the tile of the plugin you want to install. You can also uninstall or update plugins from this dialog in a similar way under the “Installed Plugins” section.

  2. Install plugins via manual input: where it says “Install by name/URL”, enter the name of the plugin you want to install (or any valid pip requirement specifier or VCS scheme). Then click the “Install” button next to the input bar. This method allows for more flexibility in the plugins you can install, but it is also a bit more advanced.
