Astrologer vs Planetdance

Planetdance, by Jean Cremers, is one of the most surprising programs in astrology: free, yet packed with features, extensible through a scripting community, and actively updated. Its trade-off is a dense, classic-Windows interface and Windows-only desktop delivery. Astrologer covers broad professional work in a modern browser workspace, with interpretation, learning, and client tools built in.
