Best free astrology software in 2026
The best free astrology software depends on the work. Soul Yatri Jyotish is built for a current Windows or macOS Vedic practice. Jagannatha Hora documents a broad Windows Vedic research toolkit. Maitreya covers Vedic and Western astrology, Astrolog offers deep Western customisation, and Morinus is a Windows desktop astrology project. This comparison uses each project's current official pages.

Which free astrology software fits your work?
Start with the astrological system and operating system. A long feature list is not useful if the program does not support the chart method or computer you use.
| Your use case | Start with | Reason |
|---|---|---|
| A current Vedic workbench on Windows and macOS | Soul Yatri Jyotish | You want a guided, local-first core for professional Vedic work and a native download path for either Windows or macOS. |
| Vedic computation and research on Windows | Jagannatha Hora (JHora) | You work on Windows and want the configurable calculation and research scope documented by its author. |
| Vedic and Western astrology in one open-source app | Maitreya | You need both Vedic and Western techniques or prefer an open-source desktop project with Linux support. |
| Freeware Western astrology and deep customisation | Astrolog | Your work is mainly Western astrology and you want a mature, scriptable program with unusually broad technical controls. |
| Western astrology on Windows | Morinus 9.6.2 | You want a focused Windows desktop astrology program rather than a general online chart service. |

What about free online astrology tools?
Online calculators are useful when you need a chart without installing anything. They are a different product category, so we keep them out of the desktop comparison.
Astrodienst (Astro.com)
A browser-based Western astrology service with free chart drawing, extended chart selection, atlas and ephemeris tools. It is an online service, not an installed desktop program.
Open the official siteAstro-Seek
A browser-based collection of astrology calculators. It belongs in an online-tools comparison rather than a desktop-software table.

Two programs can use different defaults and still be internally consistent. Test with identical inputs rather than treating a polished interface as an accuracy test.
- 01Match birth date, exact local time, coordinates, time zone and daylight-saving handling.
- 02Match ephemeris version, zodiac, ayanamsa, node model, house system and chart rules.
- 03Use reference charts near sign, house and nakshatra boundaries, where settings matter most.
- 04Confirm export, backups and installer verification before moving a working client archive.
Free astrology software FAQ
- What is the best free Vedic astrology software?
- Soul Yatri Jyotish is a strong fit for a modern Windows or macOS workflow with D1-D60, dashas, strength analysis, Jaimini, KP and reports. Jagannatha Hora is the established Windows research choice. Maitreya is useful when one open-source program must cover both Vedic and Western astrology. The right choice still depends on your operating system and calculation settings.
- Is Soul Yatri Jyotish completely free?
- The current Soul Yatri Jyotish desktop release is free to download, and its core calculation workspace is not ad-supported. Account-backed marketplace, cloud, consultation and update features use an internet connection and can have separate current terms.
- Which free astrology software works on both Windows and macOS?
- Soul Yatri Jyotish, Maitreya and Astrolog publish Windows and macOS paths. Check each project’s current system requirements and installer-verification notes before downloading. Jagannatha Hora documents Windows as its native platform.
- Which free program supports both Vedic and Western astrology?
- Maitreya explicitly describes itself as an open-source platform for Vedic and Western astrology. Soul Yatri Jyotish is centred on professional Vedic practice, Astrolog documents Western techniques, and Morinus is a Windows desktop astrology project.
- Will two astrology programs calculate the same chart?
- Do not assume they will. Use the same birth data, coordinates, time-zone and daylight-saving rule, ephemeris version, zodiac, ayanamsa, node model, house system and divisional-chart rules. Displaying more decimal places does not by itself prove better accuracy.
