Astrologer vs Solar Fire

Solar Fire is the software many professional astrologers grew up on — exhaustive technique coverage, deep predictive tools, and decades of refinement. It is Windows-only and costs $360 for a new license. Astrologer brings a broad Swiss Ephemeris chart studio, including primary directions, to any browser and surrounds it with learning, AI, and client-practice tools.

The 46 public calculators and a birth chart need no account. Saved charts, timing, AI, and client tools are on a paid plan from $27/mo, with a 14-day trial that takes a card.
