Astrologer vs Morinus

Morinus is a free, open-source astrology program with a devoted following among traditional and Hellenistic practitioners, prized for precise traditional techniques — primary directions, profections, and dignities — at no cost. It is a desktop download with a utilitarian, technique-first interface. Astrologer covers the same traditional essentials in a modern browser workspace, also free, with interpretation and learning tools alongside.
