# Dynamic features on a static site

Extensions add blocks and admin pages from an external app, and Forms collect submissions without a server of your own. The website itself stays static.

EXTENSIONS

## Add an app to your site

An Extension lets an external app add blocks and admin pages to a Typeroll site. The provider keeps its code, backend and data in its own cloud.

Once it is installed, editors add its components to a page like any other block.

## How Extensions work

### Two ways to run

A bundled component is copied into the site at build time and checked against its hash. An embedded app runs in a sandboxed frame on the provider’s own domain.

### Declared up front

Each release has a manifest that declares its permissions, components, API and events. Published versions never change.

### You approve the scopes

Admins approve the scopes when they install an Extension, and new releases never widen them on their own.

### Build your own

Start from the extension starter and the live reference demos.

FORMS

## Forms with an inbox

Contact forms and multi-step funnels work on a static site: validation, partial saves, a submissions inbox, email notifications and webhooks.

Extensions can submit into the same Forms, so a lead tool needs no backend of its own.
