Accelerate your next Gatsby project

Test Themes npm PRs Welcome

Gatsby Theme Catalyst is an an opinionated set of integrated themes and starters that can be used as a boilerplate to accelerate your next Gatsby project. There is a single "core" theme in which most dependencies and utility components are contained followed by progressively more styled and refined child themes and starters. These themes use Theme-UI and MDX.

Catalyzing Start:

   # create a new Gatsby site using the basic starter
    gatsby new catalyst
   # change into your new directory
    cd catalyst
   # launch the site
    gatsby develop

Example sites built with Gatsby-Theme-Catalyst:

Less is more

Simple Core Theme

gatsby-theme-catalyst-core was designed and built to be as simple and unstyled as possible. A barebones starting point which can be easily maintained in the future to manage dependencies on client sites.

Child themes to extend the core theme

These child-themes are focused on extending function and remain as design-agnostic as possible. Again this makes longterm maintenance easier for client sites. It is my preference to begin new projects without too much styling that has to be undone.

Starter sites to extend and style the themes

The starter sites provide a "quick start" for site development using the themes as dependencies. Currently the starter sites only provide basic implementation of the themes. It is my vision however that in time there could be more styled and complex starters released which do not need as much customization and include more rigid styling.


This is a passion project for me that I work on in my spare time. I would love any additional feedback, suggestions and pull requests. Contributions are welcomed and encouraged.

I would like to acknowledge all of the help I have gotten in working on this project from people answering questions on the GatsbyJS issues, Chris Biscardi's blog, and the work that @4lpine and @jxnblk have done documenting Theme-UI so well.

The vision for this set of themes was heavily influenced by WP Rig and Underscores from the Wordpress world. My hope was to create a similar kind of simple boilerplate that could be used as a jumping off point for custom work.

You can’t perform that action at this time.
