Foundations are things you can “see,” such as buttons and panels. Buttons can trigger workflows, and panels embed information from somewhere else on the web.


Readers do just that — read data or “scrape” a webpage. Readers can extract data from a page's HTML or read data directly from the most popular web frameworks.


Effects take an input and perform an action. Effects range from opening a new tab, to inputting text into a search bar, to appending a row to a spreadsheet.


Transforms take an input and produce an output. Examples of this include calling an API, running a JSON transform, and parsing text.


Renderers show information on a page as an interactive web component or static HTML. Examples include rendering Markdown, or showing data in a table.


Services are reusable resources and configurations, such as a Google Sheet or Slack channel you can securely share. They can also be used to authenticate requests to service APIs.

“Being able to add PixieBrix to my tool belt has opened up so many more possibilities for automating and integrating the tools I use every day."
