Metalsmith is a simple, pluggable static site generator that uses a simple directory structure and a series of plugins to transform and build your content into a static website. It has a minimalistic approach, with no built-in assumptions about how your content should be organized, allowing you to structure your content in any way you see fit.
Another advantage of Metalsmith is its flexibility. Because it’s a pluggable system, you can easily add or remove functionality by installing or uninstalling plugins. This allows you to tailor the system to your specific needs and avoid the bloat that can come with more complex frameworks.
Metalsmith is also very fast. Since it’s a static site generator, all the content is pre-built at build time, so there’s no need for a server-side database or rendering engine. This makes it an excellent choice for building websites that need to load quickly and efficiently.
