1. Natal Echo: best for beginners who want the full picture

Natal Echo gives you a complete chart with planets, all twelve houses, aspects and your Rising sign in under a minute, without an account. It's built for people who want to understand their chart, not just see a wheel: every placement links to a guide, and the site has more than 500 free articles covering planets in houses, aspects and the 12 houses.

What stands out is the set of free timing tools: an eclipse house finder, solar return, lunar return, progressions, and house finders for Jupiter, Saturn, the North Node and Mercury retrograde. You can also download your chart or turn it into a printable poster.

Good to know: charts use the Placidus house system only. If you prefer whole-sign houses, Astro.com or Astro-Seek give you more control.

2. Astro.com: best for advanced users

Astro.com (Astrodienst) is the long-standing reference site for astrologers. Its Extended Chart Selection lets you choose house systems, asteroids and drawing styles, and it gives free access to Astro-Databank, a large collection of birth data for famous people. It also offers ephemerides built on the Swiss Ephemeris, and a Personal Eclipse Horoscope report that shows which house each eclipse falls in.

Good to know: the interface is dense for beginners. A paid subscription adds extended storage for saved charts.

3. Astro-Seek: best for the most free tools

Astro-Seek offers a very wide set of free calculators: natal charts, synastry, composite charts, transits, progressions, eclipse calendars and a tool for viewing transiting eclipses in your natal chart, with several house systems to choose from.

Good to know: the sheer number of options and the busy layout can overwhelm newcomers.

4. Cafe Astrology: best classic written report

Cafe Astrology has offered free chart reports since 2002. Its free natal report lists your planets by sign and house, your aspects, and long written interpretations. It also offers a free compatibility report, transit reports, Solar Return reports and a Progressions report.

Good to know: the site's design feels dated, and the reports are long reads rather than quick lookups.

5. Co-Star: best social astrology app

Co-Star is a free mobile app with in-app purchases. It's known for its minimalist design, daily push notifications, and the ability to add friends and compare charts.

Good to know: it's app-only and focused on daily messages rather than deep chart study. Looking for something browser-based with houses? See our free Co-Star alternative guide.

6. CHANI: best guided, wellness-style app

CHANI is a free-to-download app with premium subscriptions that unlock all content, priced at $11.99 a month or $107.99 a year on the App Store. It focuses on guided horoscopes, rituals, journal prompts and meditations.

Good to know: most of the depth sits behind the subscription.
