Add-ons are organized bundles of code that you can use to add functionality on to PyroCMS. You can either create your own, or use some of the add-ons available on the PyroCMS store.
Add-ons are organized into four different types based on their structure and use: Plugins, Widgets, Field Types, and Modules .
The PyroCMS Store
The official listing of PyroCMS add-ons is on the PyroCMS store. Despite the name, many of the add-ons found on the store are free. If you have created an add-on and would like to have it available on the PyroCMS store, you can submit it for review.
Creating Your Own Add-ons
Add-on development for PyroCMS is a great way to extend the functionality of PyroCMS in an organized way. Check out the developer docs to learn about how add-on building works.
