Rating Breakdown
Overview
Astro.com, operated by Astrodienst AG in Zurich, Switzerland, is the most authoritative free astrology resource on the internet. Founded by Alois Treindl in 1996, the site provides professional-grade chart calculation tools that are used by amateur enthusiasts and professional astrologers alike. The Astro-Databank, an encyclopedia of celebrity and notable birth charts, is an invaluable research resource. The site reflects Swiss precision — technically excellent and scientifically rigorous in its astronomical calculations.
Reading Experience
The chart calculation engine on Astro.com is the most accurate publicly available tool for natal, transit, synastry, composite, and solar return charts. Charts are generated as high-quality graphics with professional formatting. The extended chart selection offers dozens of chart types and house systems. The free personal portrait (Astro Click Portrait) provides interactive chart exploration where clicking any point reveals its interpretation.
Psychic Selection
Astro.com draws from a network of respected astrologers for its interpretive content. The free horoscopes are written by Robert Hand, Liz Greene, and other recognized names in professional astrology. The chart calculation engine is based on the Swiss Ephemeris, the most accurate astronomical calculation library available, used by professional astrology software worldwide. This is not psychic content — it is rigorous astrological analysis.

Who Is It For?
Astro.com is essential for anyone serious about astrology — from intermediate students to professional astrologers. The depth of tools and accuracy of calculations make it the industry standard.
