FateChart vs Astro.com: the reference site vs the modern free multi-system chart
Astro.com (Astrodienst) is where serious Western astrologers check their numbers. FateChart is for people who want that accuracy without a registration form, and want the Chinese-astrology view of the same birth on the same page.
Pick Astro.com if you want Liz Greene or Robert Hand reports, Astrodatabank with Rodden ratings, or dozens of chart styles and house systems. Pick FateChart if you want the chart free without registering, want BaZi and Zi Wei Dou Shu alongside the Western chart, want Asian-language interfaces, and would rather pay US$3.99 for an AI reading than US$69.90 for a report.

Where Astro.com is strong
- Swiss Ephemeris — the calculation library many other astrology programs license — is theirs, and is documented in depth.
- Paid reports written by named, published astrologers (Liz Greene, Robert Hand) rather than generic text.
- Astrodatabank: tens of thousands of celebrity and historical charts with source reliability ratings.
- Twelve interface languages including German, French, Spanish, Chinese and Japanese, and a free ephemeris spanning centuries.
Where FateChart is the better pick
No registration to see your chart
Astro.com requires an account to use Extended Chart Selection. FateChart shows the full natal chart, BaZi, Zi Wei and numerology with no sign-up.
Chinese astrology included
Astro.com has no BaZi, Zi Wei Dou Shu or numerology. FateChart casts all three from the same birth data, free.
US$3.99 instead of US$69.90
Astro.com’s single reports are about US$69.90 each. FateChart’s AI reading is US$3.99 for 10 credits, and is clearly labelled as AI — it is not a substitute for a Liz Greene report, and we do not claim it is.
Birth data stays in your browser
FateChart does not store birth data on the server. Astro.com keeps profiles on its servers; a deleted profile persists for six months per its privacy statement.
Made for phones and for Asia
FateChart is mobile-first and adds Korean, Vietnamese, Thai and Indonesian to the Chinese and Japanese that Astro.com also offers.
Free PDF and share link, free Life K-Line
Astro.com charges US$39.90/year for PDF chart drawings. FateChart’s report PDF, read-only share link and Life K-Line curve are free.
Using FateChart alongside Astro.com
Cast the same birth on both. Planet positions should agree to the minute — FateChart uses standard ephemeris data and Placidus by default. Then open the BaZi and Zi Wei tabs for the part Astro.com has never covered. Keep Astro.com for astrologer-authored reports and Astrodatabank research.
FateChart vs Astro.com: common questions
Is FateChart as accurate as Astro.com?
For natal placements, both use standard ephemeris data and the results agree; FateChart publishes its time-zone and true-solar-time handling on a methodology page. Astro.com offers far more chart styles and techniques for specialists.
Do I need an account on FateChart?
No. Every chart — Western, BaZi, Zi Wei Dou Shu, numerology — is free without signing up. Astro.com requires registration to use Extended Chart Selection.
Is FateChart’s AI reading comparable to a Liz Greene report?
No, and we do not claim that. Astro.com’s reports are written by named astrologers and cost about US$69.90. FateChart’s reading is AI-generated from your full chart, labelled as such, and costs US$3.99 for 10 credits — a different product at a different price.
Does Astro.com do Chinese astrology?
No. Astro.com covers Western astrology only. FateChart adds BaZi, Zi Wei Dou Shu and numerology from the same birth data, free.
Which has more celebrity charts?
Astro.com’s Astrodatabank is far larger and includes source ratings. FateChart has hundreds, each shown in Western, BaZi and Zi Wei at once.
