28.1. QGIS Plugins
QGIS has been designed with a plugin architecture. This allows many new features and functions to be easily added to the application. Some of the features in QGIS are actually implemented as plugins.
28.1.1. Core and External plugins
QGIS plugins are implemented either as Core Plugins or External Plugins.
Core Plugins are maintained by the QGIS Development Team and are automatically part of every QGIS distribution. They are written in one of two languages: C++ or Python.
Most of External Plugins are currently written in Python. They are stored either in the ‘Official’ QGIS Repository at https://plugins.qgis.org/plugins/ or in external repositories and are maintained by the individual authors. Detailed documentation about the usage, minimum QGIS version, home page, authors, and other important information are provided for the plugins in the Official repository. For other external repositories, documentation might be available with the external plugins themselves. External plugins documentation is not included in this manual.
To install or activate a plugin, go to .
Installed external python plugins are placed under the
folder of the active user profile path.
Paths to Custom C++ plugins libraries can also be added under.
28.1.2. The Plugins Dialog
18.104.22.168. The Settings tab
At the bottom of the left panel, the Settings tab is the main place you can configure which plugins can be displayed in your application. You can use the following options:
Check for Updates on Startup. Whenever an installed plugin has update available, QGIS will inform you Every Time QGIS starts, Once a Day, Every 3 Days, Every Week, Every 2 Weeks or Every month.
Show also Experimental Plugins. QGIS will show you plugins in early stages of development, which are generally unsuitable for production use. For these plugins, you can install either the stable or the experimental version, and at any moment switch from one to the other.
Show also Deprecated Plugins. These plugins are usually unmaintained because they have replacement functions in QGIS, a lack of maintainers, they rely on functions that are no longer available in QGIS… They are generally unsuitable for production use and appear grayed in the plugins list.
By default, in the Plugin Repositories section, QGIS provides
you with its official plugin repository with the URL
<version> represents the exact QGIS version you are running).
To add external author repositories, click Add…
and fill in the Repository Details form with a name and the URL.
The URL can be of
file:// protocol type.
The default QGIS repository is an open repository and you don’t need any authentication to access it. You can however deploy your own plugin repository and require an authentication (basic authentication, PKI). You can get more information on QGIS authentication support in Authentication chapter.
If you do not want one or more of the added repositories, they can be disabled from the Settings tab via the Edit… button, or completely removed with the Delete button.
22.214.171.124. Browsing the plugins
The upper tabs in the Plugins dialog provide you with lists of plugins based on their install, creation or update status. Depending on the plugins settings, available tabs can be:
All: shows all the available plugins in the enabled repositories
Installed: shows both the plugins you installed and the core plugins that are installed by default and you can not uninstall
Not installed: shows uninstalled or not yet installed plugins in the enabled repositories
New: shows plugins released since the last Check for Updates on Startup
Upgradeable: shows installed plugins that have published a more recent version in the repository
Invalid: shows all installed plugins that are currently broken for any reason (missing dependency, errors while loading, incompatible functions with QGIS version…)
At the top of the tabs, a Search function helps you find any plugin using metadata information (author, name, description, tag,…).
Select a plugin and you will have some metadata displayed in the right panel:
information on whether the plugin is experimental or has an experimental version available (if Show also Experimental Plugins is checked)
summary and description
rating vote(s) (you can vote for your preferred plugin!)
some useful links to the home page, tracker and code repository
version(s) available with link to download page in the repository, or path to local folder for installed plugins
The Plugin Manager dialog allows you to interact with the latest version of the plugins. When enabled, the experimental version can be shown only if it is more recent than the latest stable version. Depending on the active tab, whether the selected plugin is installed, you will be given some of the following options:
Install: installs the latest stable version of the selected plugin
Install Experimental Plugin: installs the experimental version of the selected plugin
Reinstall Plugin: installs the same stable version of the plugin e.g. after it has failed to load
Reinstall Experimental Plugin: installs the same stable version of the plugin e.g. after it has failed to load
Upgrade Plugin: upgrades selected plugin to its latest stable version
Upgrade Experimental Plugin: upgrades selected plugin to its experimental version
Upgrade All: upgrades all installed plugins to their more recent stable or experimental version (depending on whether their previously installed version was stable or experimental).
Downgrade Plugin: moves from the experimental version of the plugin to its previous stable version
Downgrade Experimental Plugin: moves from an experimental version of the plugin to its latest published experimental version. This may occur when playing with a not yet published version.
Uninstall Plugin: removes the installed plugin from the user profile
An installed plugin displays a checkbox on its left. Uncheck it to temporarily deactivate the plugin.
Right-click on a plugin in the list and you will be able to sort the plugins list by various metadata. The new order applies to all the tabs. Sort options are:
Sort by Name
Sort by Downloads
Sort by Vote
Sort by Status
Sort by Date Created
Sort by Date Updated
126.96.36.199. The Install from ZIP tab
The Install from ZIP tab provides a file selector widget to import plugins in a zipped format, e.g. plugins downloaded directly from their repository. Encrypted files are supported.
