| Resource | Platform | Free and paid access | What to check |
|---|---|---|---|
| Astrolog | Publisher lists Windows, Unix, and Macintosh versions. | Freeware; source code is available. | Check the download instructions for your platform and whether a build step is needed. Official source |
| Planetdance | Windows program. | Free program; the publisher also accepts donations. | Review usage terms and the ephemeris coverage included with the installer. Official source |
| Jagannatha Hora | Windows; the official requirements page lists older Windows versions. | Free Vedic astrology software. | Modern OS compatibility has not been tested here. The publisher does not describe a native Mac version. Official source |
| TimePassages | Publisher lists Windows, macOS, Android, and iPhone products. | Paid desktop editions; mobile downloads and paid features vary. | Compare the edition and platform-specific offer. A free download does not mean every feature is free. Official source |
Publisher information checked 6 September 2026. This is a comparison of published features, not a score for predictive accuracy or a hands-on installation test. The order is not a ranking. Confirm the current offer on the official website.
Free software is not the same as a free download
Astrolog, Planetdance, and Jagannatha Hora are described as free programs by their publishers. TimePassages has platform-specific products and paid editions. The table separates those offers rather than presenting every download as a fully free product.
The table is based on official publisher information checked on 6 September 2026. We have not installed or benchmarked these programs, tested their predictive accuracy, or verified compatibility with every current operating system.
For Windows, compare the actual requirements
Planetdance is presented as a Windows program. Jagannatha Hora’s official page lists older Windows requirements, so check compatibility for your current system before relying on it. A third-party claim about a modern system should not replace the publisher’s instructions.
Choose the program around the work you need to do, then read its documentation and usage terms. Check which files and data are included rather than downloading an unfamiliar mirror or repackaged installer.
For Mac, distinguish native support from source code
Astrolog lists Macintosh versions and makes source code available, while TimePassages advertises macOS products. That does not make every available file ready to run on every Mac. Check the particular release, installation process, and system requirements.
Jagannatha Hora’s official page does not describe a native macOS application. Compatibility layers are a separate setup with their own requirements; this directory has not tested them.
Match the software to your astrology approach
Jagannatha Hora is described as Vedic astrology software. Other programs may offer multiple techniques or settings. Review the feature list and manual for the tradition and calculations you want rather than choosing from a name alone.
If you only want to view a chart occasionally, a browser-based chart resource may be easier to explore than desktop software. The birth-chart category includes official website links for that purpose.
A short download checklist
Before installing, confirm the publisher, operating system, edition, price, usage terms, included data, and support resources. Use the official download page and keep a note of the version you chose.
