Apaxy is a customisable theme built to enhance the experience of browsing web directories. It uses the mod_autoindex Apache module—and some CSS—to override the default style of a directory listing. It is similar to h5ai.

Apaxy may be basic, but it gives you a great deal of creative freedom when styling your directory. You can make it pop with Javascript or jQuery. You can also add welcome messages, download instructions or copyright notices. Best of all, you can add custom mime type icons.
