Horosa: Offline workstation for Chinese and Western metaphysics tools
Render 3D planetarium views, compute Bazi and Ziwei charts, and run local AI-assisted readings without an internet connection. Horosa, created by Horace-Maxwell, packages Chinese systems and Western astrology into a single desktop workstation for Windows. The app includes an offline AI bridge, support for more than 26 main techniques and 60 sub-techniques, and local-first storage. It fits professional metaphysics practitioners and researchers who need cross-disciplinary charts and private, offline analysis.
What does Horosa actually perform for practitioners?
The tool combines traditional astrological calculations with astronomical rendering. It produces charts for Ziwei Dou Shu, Bazi, Qimen Dunjia, and Western Astrology while offering a 3D planetarium for positional context. The app exposes over 110 distinct technique tools, and maintains a high-quality birth-time and coordinate database so calculations use local reference data rather than remote lookups.
How light is Horosa on a Windows desktop during use?
The runtime is designed for a desktop shell that keeps resource use modest. The app runs in a Tauri-based container with a React interface, which reduces the native binary bulk compared with traditional heavy frameworks. The local-first design means calculation engines execute locally, avoiding continuous network I/O and keeping background activity limited to local CPU cycles and memory during chart generation.
Is using Horosa safe for private birth data and sensitive records?
Privacy is delivered by storing data locally and omitting a login system. The app's local-first data storage keeps birth records on the machine, and the horosa-skill MCP server mounts AI skills to local models, enabling AI analysis without sending data to cloud services. That architecture maintains data sovereignty and removes the need for remote account credentials.
Does the app require specialist knowledge to operate effectively?
The learning curve leans toward experienced practitioners rather than casual users. The range of techniques, the presence of advanced modules like MCP-mounted AI skills, and the depth of Chinese and Western systems mean the interface assumes user familiarity with metaphysical terminology and chart interpretation. The developer provides source code and dedicated builds for Windows, which suits technically inclined users who want to adapt or extend the tool.
A focused choice for specialists who need offline, privacy-respecting analysis
Horosa suits practitioners and researchers who require local computation, multi-tradition charts, and the option to run AI models on-premises. The main trade-off is the specialist orientation: casual users may find the breadth of techniques and assumed domain knowledge daunting. For anyone working with sensitive birth data and cross-disciplinary astrological research, the app delivers a practical, privacy-minded workstation with that single usability trade-off.
