Stacks API v13 for Stacks 5.0
Stacks can be extended in two complementary ways. Choose the API that matches what you want to build.
Build reusable components that people add to a page: content, controls, containers, layouts and other page-building elements.
Use the Stack API documentation for .stack and .devstack bundles, Info.plist properties, inspector controls, templates, assets and libraries.
Build the document-level presentation around a page: HTML structure, metadata, navigation, content placement, stylesheets, scripts and theme controls.
Use the Theme API documentation for .stackstheme and .devstackstheme bundles, named templates, runtime objects and theme inheritance.
Both APIs are part of the Stacks developer platform. A theme provides the page shell while stacks provide the components placed within it.
Stack developers discuss building, marketing and selling Stacks products in the public Slack community.
