A Free Blogging Theme

Hydejack started out as a free blogging theme for Jekyll — and continues to be so.

Just Markup

Hydejack boasts a plethora of modern JavaScript, but make no mistake: It’s still a plain old web page at its core. It works without JavaScript, and you can even view it in a text-based browser like w3m:
