Our verdict on Kepler
Kepler brings a wide range of astrology work into a Windows desktop application, serving users from beginners to professional astrologers. Its chart tools cover natal, progression, solar and lunar return, relocated, composite, and harmonic charts, alongside synastry comparisons and compatibility scores. This breadth suits solo practitioners or small practices that want chart analysis, forecasts, relationship work, and reports in one paid suite rather than a narrow chart calculator.
Forecasting and reference tools are a notable part of the package. Kepler calculates transit-to-natal and other forecasts, and includes Vedic charts such as varga charts and a nakshatra wheel. AstroMaps, EclipseMaps, ephemerides, a moon calendar, a star catalogue, and a sky map add reference and mapping options. Chart wheels include multi-wheel views and customizable styles. For practitioners who prepare written material, natal listings and interpretive reports can be exported as PDF, RTF, TXT, or HTML; optional interpretive-report add-ons are also available.
The published plans show two purchase formats at $300 one time: Kepler Download and Kepler CD. The download plan provides the download version, while the CD plan includes the CD version and has extra shipping and handling charges. This is a substantial upfront purchase rather than a free or subscription option, so its extensive feature set is most relevant to people expecting to use several chart systems and reporting tools. It is a less suitable fit for Mac users or buyers looking for a lower-cost entry point. Kepler is sold for Windows, with email support; those who need another platform should consider an alternative.
