Human Design About

Someone introduced me to Human Design, and what caught my attention was the engineering behind it. Every chart depends on the exact positions of the Sun, the Moon and the planets at two moments, and I wondered what it would take to calculate them properly, without relying on anyone else's software. This site is the result of that curiosity. It was also a good reason to put RIFE2, my own web framework, through its paces, and in particular its template engine, which draws every chart here as SVG. That's a use of a template engine I haven't seen much before, and the browser shows the charts as they are, without any image library or JavaScript framework.

Everything is calculated from scratch in pure Java. The positions come from tables fitted to the JPL ephemerides, and they're checked against two thousand reference charts made with the Swiss Ephemeris. The people you save stay in your own browser, they're never stored by this site.

I'm not a Human Design practitioner, and this site doesn't offer readings or advice. The descriptions below the charts and in the Learn pages introduce what each part of a chart means within Human Design, following its own literature, so that you can explore it and decide for yourself what it means to you.

The site is free, without ads or tracking. If you're curious about the other things I make, you'll find them at uwyn.com.
