I built this page with ButterCMS, a headless CMS (Content Management System).
A headless CMS differs from a traditional CMS (such as Wordpress, Drupal, and Joomla) by separating the front end from the back end. Content in a headless CMS (like the text you're reading now, and images like my cartoon avatar) is managed separately from the code for the site. ButterCMS can pair with any rendering framework and cloud deployment platform. In my case, I'm using Astro.js to render the front end and Vercel for deployment.
