This is the development page for the little flat file content management system "Gravitron", running on — you already guessed it:

This is not production ready yet. Development is live here, so expect a little hiccup from time to time. For details see the project status page.

Think of Gravitron as Gravs very little (and very ugly) brother: It comes with many core features borrowed from its older sibling, but is slimmer and by far not as feature rich.

I love Grav, don't get me wrong — But if you ever wanted to set up a little low-feature 5-page site before going to sleep in 20 minutes, this might be just the right CMS for you.

Gravitron needs at least PHP 8.1.0 to run (a Twig 3.x requirement) and comes bundled with:

• Twig 3.22.1: The flexible, fast, and secure template language for PHP (MIT License)
• Parsedown 1.80: The better Markdown Parser in PHP (MIT License)
• Parsedown Extra 0.8.0 (optional): An extension to Parsedown that adds support for Markdown Extra (MIT License)
• SimpleLightbox 2.13.0 by Andre Rinas: A touch-friendly image lightbox (MIT License)
• The Manrope font (SIL OFL)
• Font Awesome 4.7 (SIL OFL)

I've kept, slimmed down, neutered, pimped, tuned and adopted:

• The pages' folder structure
• Markdown and Twig syntax for pages (at least a most of it...): An existing Grav page file works instantly
• Media file support (images, PDF documents, etc.) in pages
• Theme support: A Grav theme almost™ works out ot the box

What you will miss (or actually not miss), compared to Grav:

• An admin panel
• Mail features
• Modular pages
• Any form processing
• Automated CSS/JS pipelining, minifying and asset management: You'll have to minify CSS & JS yourself
• Fancy blogging things like taxonomy filters
• Search functions
• Complex debugging tools
• Complex error handling:
  • A) There are no errors and
  • B) Should there be an error, it is routed to the error page
• Some Twig features

Admit it: After all, how many percent of the complete feature set do you actually use?
