Checked October 2026

Each of these does something well. Co-Star and The Pattern are phone apps built around daily, personalized updates and friends. Astro-Seek and Astro.com are websites with deep technical settings for people who like to adjust every option. ZodiacTales is a website that puts Western astrology and the Chinese zodiac side by side, with written readings and no account. The table below sets out the facts so you can pick what suits you.

Frequently asked questions

Is there a free Co-Star alternative without an app?

Yes. ZodiacTales, Astro-Seek and Astro.com all run in a web browser, and their natal charts are free. ZodiacTales needs no account at all, and its chart comes with a written reading. Co-Star and The Pattern also offer a free natal chart on their websites, which asks for an email address, while their full experience lives in their iOS and Android apps.

Which site does Chinese zodiac and Western astrology together?

ZodiacTales covers both: a Western natal chart and synastry on one side, and the Chinese year animal, the Five Elements and a full Four Pillars (BaZi) calculator on the other, plus pages for all 144 Chinese and Western sign combinations. Astro-Seek has a Chinese zodiac sign lookup alongside its Western tools. Co-Star, The Pattern and Astro.com do not list Chinese astrology among their features.

Do I need an account to get my birth chart?

Not on ZodiacTales: there is nothing to sign up for. Astro-Seek and Astro.com also work without registering, with an optional free account to save birth data. The Co-Star app asks for a phone number or Apple account, and the free web charts from Co-Star and The Pattern ask for an email.

It depends on what you want. If you want to adjust house systems, chart types and other technical settings, Astro-Seek and Astro.com offer the most options. If you want a chart explained in plain written language, without an account, ZodiacTales is built for that, and it adds the Chinese side of your chart too.
