Astrologer vs Morinus

Morinus is free, open-source Windows astrology software with a devoted following among traditional and Hellenistic practitioners, prized for primary directions, profections, and dignities. The actively maintained fork reached version 9.6.2 in March 2026. Astrologer now supports primary directions too, but pairs the calculation work with a modern browser interface, interpretation, learning, and client tools.

Does Morinus run in a browser?

No — Morinus is a desktop program you download. Astrologer runs in any browser with nothing to install, including on phones and tablets.
