unified

Content as structured data

We compile content to syntax trees and syntax trees to content.
We also provide hundreds of packages to work on the trees in between.
You can build on the unified collective to make all kinds of interesting things.

Build

We provide the building blocks: from tiny, focussed, modular utilities to plugins that combine them to perform bigger tasks. And much, much more. You can build on unified, mixing and matching building blocks together, to make all kinds of interesting new things.
