Pyramid add-ons extend the functionality of Pyramid, such as adding an ORM, sending email, or using a template-based language. The Python Package Index trove classifier "Framework :: Pyramid" is used by over 350 packages. Official add-ons (supported by the Pylons Project), popular add-ons from the community, and other web-related packages are listed below.
"Development environments" are packages which use Pyramid as a core, but offer alternative services and scaffolding to ease web application development. Each development environment presents a set of opinions and a "personality" to its users. Some could be labeled "content management system" or "admin interface". Although users of a development environment can still use all of the services offered by the Pyramid core, they are usually guided to a more focused set of opinions offered by the development environment itself. Development environments often have dependencies beyond those of the Pyramid core.
