Some static site generators that work with Markdown:
- Jekyll is very popular and also the engine behind GitHub pages.
- Python variants: Hyde or Pelican
- nanoc (used f.ex. in the GitHub API documentation)
- Middlemanapp: maybe the best one?
I think none of them use pandoc (maybe because it's written in Haskell), but they all use an enhanced Markdown syntax or can be configured to use pandoc.
Other interesting ways to generate a site from markdown:
- Markdown-Wikis that are file based: f.ex. Gollum, the Wiki-Engine that is also used by GitHub
- Telegram: commercial; written by David Pollak, the inventor the Lift-Scala-framework
Engines that use Pandoc:
- Gitit: Pandoc Wiki
- Pandoc-Plugin forIkiwiki
- Yst static site generator
- Gouda - generates a site from a directory of markdown files
- Rippledoc - generates a navigable site from nested directories of markdown files
