Pufferfish is an extensible html templating engine that generates raw html, meaning that it will not affect load times of websites. A full-blown javascript framework is sometimes a bit overkill for a static website. Pufferfish adds some simple templating to html so you don't have to use such a framework for small projects or for pages that require fast loading. Pufferfish will compile your files to raw html. For more information on its usage, see Pufferfish's GitHub page.
