Hydejack’s cover page on a variety of screen sizes.

Hydejack is a boutique Jekyll theme for hackers, nerds, and academics, with a focus on personal sites that are meant to impress.

It includes a blog that is suitable for both prose and technical documentation, a portfolio to showcase your projects, and a resume template that looks amazing on the web and in print.

Your complete presence on the web — A blog, portfolio, and resume.

A Personal Site That Won’t Disappear

Hydejack is 100% built on Open Source software, and is Open Source itself, save for parts of the PRO version. The PRO version is a one-time payment that gives you the right to use it forever.

Hydejack is all static sites. HTML. All you need is a web server — any web server — to have a professional web presence that lasts a lifetime.

Just Markdown

Write all content with Markdown. Hydejack gives you additional CSS classes to stylize your content, without losing compatibility with other Jekyll themes.

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:

Syntax Highlighting

Hydejack features syntax highlighting, powered by Rouge.

<!-- file: `_includes/my-body.html` -->
<script type="module">
  document.querySelector("hy-push-state").addEventListener("hy-push-state-load", () => {
    const supportsCodeHighlights = false; // TBD!!

Code blocks can have a filename and a caption.

Beautiful Math

They say math is beautiful — and with Hydejack’s math support it’s guaranteed to also look beautiful: ϕ(x,y)=ϕ(i=1nxiei,j=1nyjej)=i=1nj=1nxiyjϕ(ei,ej)=(x1,,xn)(ϕ(e1,e1)ϕ(e1,en)ϕ(en,e1)ϕ(en,en))(y1yn)\begin{aligned} \phi(x,y) &= \phi \left(\sum_{i=1}^n x_ie_i, \sum_{j=1}^n y_je_j \right) \\[2em] &= \sum_{i=1}^n \sum_{j=1}^n x_i y_j \phi(e_i, e_j) \\[2em] &= (x_1, \ldots, x_n) \left(\begin{array}{ccc} \phi(e_1, e_1) & \cdots & \phi(e_1, e_n) \\ \vdots & \ddots & \vdots \\ \phi(e_n, e_1) & \cdots & \phi(e_n, e_n) \end{array}\right) \left(\begin{array}{c} y_1 \\ \vdots \\ y_n \end{array}\right) \end{aligned}

Hydejack uses KaTeX to efficiently render math.
