What is Astro.com?

Astro.com (Astrodienst) is the gold standard for professional astrological charting, founded in 1980 by Alois Treindl in Zurich. It offers free natal charts, transit forecasts, synastry overlays, and a massive library of interpretive text by professional astrologers (Liz Greene, Robert Hand). The site serves both beginners and professional astrologers with the most precise ephemeris calculations available online.

It offers dozens of chart types (natal, progressed, solar return, harmonic, composite), multiple house systems, asteroid positions, and professional-grade Liz Greene psychological horoscope reports. For a serious student or professional astrologer who needs precise charts and classical interpretations, Astro.com is the reference standard.

Where Book of Life differs

Astro.com focuses exclusively on astrology. Book of Life combines natal astrology with 12 additional systems — Matrix of Destiny, Human Design, tarot, I Ching, runes, Bazi, numerology, chakras, Jung archetypes, synastry, lunar calendar, and Celtic Tree Horoscope — in one unified document. Book of Life generates AI-personalised interpretations that synthesise across systems (not just generic text blocks), packages everything into a printable PDF book, and is built specifically for practitioners who resell reports to clients. Astro.com's reports are for personal use; Book of Life's are business tools.
