Our Open Source Commitment
Astrologer Studio v2.0
Astrologer Studio v2 has been completely rebuilt from scratch. Every aspect of the platform — from the charts to the interface to the calculation engine — has been redesigned to be faster, more precise, and ready for the features our users have been asking for.
How We Calculate Your Charts
We are the creators and maintainers of bothlibephemerisandKerykeion.
- libephemeris supports compact LEB artifacts derived from JPL ephemerides, together with explicit source and coverage metadata.
- Kerykeion v6 is our astrology engine, used by thousands of astrologers and researchers worldwide. It turns raw astronomical data into the charts, aspects, and houses you work with every day.
We are rolling out a sealed runtime that keeps chart-time calculations on locally provisioned data and reports the source class used for ephemeris-backed, derived and analytical points. Until that engine release is deployed, these guarantees should not be read as a claim about every live result.
Supporting Free Software
Astrologer Studio is a commercial product, but it exists to sustain free software. Revenue from subscriptions directly funds the ongoing development of libephemeris and Kerykeion, which remain free and open-source for the entire community.
We believe that professional software and open source are not in conflict — one can sustain the other.
Future: Community OSS Edition
We are planning a community open-source edition of Astrologer Studio in the future. Details and timeline will be announced on ourblog.
In the meantime, Astrologer Studio v1 (the original version) remains freely available on GitHub:
