Real astronomy.
Astrology with soul.
Astrogoy was born from the conviction that astrology deserves tools as precise and beautiful as the discipline itself.
A project born from a simple question
Why do all astrology apps offer approximate calculations, outdated designs, or generic interpretations copied from 1980s books? Astrology is a discipline with thousands of years of history and deserves to stand at the height of the 21st century.
Everything was built from scratch: planetary calculation with Swiss Ephemeris — the same engine Astrodienst uses — the Placidus house system with real astronomical precision, and an interactive natal wheel designed pixel by pixel. Every architectural decision responds to a clear vision of the final result.
Modern tools, including artificial intelligence, accelerate execution. But they do not replace judgement, organization, or domain knowledge. Behind every function are concrete human decisions: what to build, how to build it, and why.
More than a horoscope app
Each natal chart is calculated with Swiss Ephemeris, the same ephemerides used by astronomers and professional astrologers. No approximate data, no shortcuts.
Verified astronomical precision"To enable every person to understand their natal chart with the same depth as a professional astrologer, thanks to astronomical precision artificial intelligence.

Precision above all
Planetary calculations run on the server with Swiss Ephemeris, the same engine used by astronomers and professional astrologers. An incorrect natal chart is worthless, no matter how beautiful it looks.
Privacy by design
Saved charts are stored encrypted in Supabase. Calculations run on the server without persisting unnecessary personal data. The user controls what they share.
AI with real context
AI-generated interpretations include the full chart context: planetary positions, houses, aspects, dignities, and element distribution. They are not generic texts.
True multilingual
Seven languages, including Latin. We do not just translate the interface: calculations, interpretations, and editorial content are designed for users across multiple cultures.
No friction
No mandatory registration to calculate your chart. No subscription to see basic results. The experience must be immediate and fluid from the very first second.
Always evolving
Synastry, transits, progressions, solar returns. The roadmap is ambitious and built by listening to users, chart by chart.
Built with the right tools
Each piece of the stack was chosen for a concrete reason. Next.js on the frontend, Swiss Ephemeris on the server, Supabase for persistence. Nothing gratuitous, nothing superfluous.
Swiss Ephemeris on server
Planetary position calculations with ~1 arcsecond precision, the same engine as Astrodienst. Asteroids (Chiron, Lilith, Ceres, Pallas, Juno, Vesta) via .se1 files. The calculation lives on the server, not the client.
Native Canvas 2D
The natal wheel is drawn with the HTML5 Canvas API. No generated SVG, no chart libraries: total control over every pixel.
State-of-the-art AI
Premium interpretations use cutting-edge artificial intelligence models, with context enriched by each user's complete chart.
Global infrastructure
Deployed on Vercel with serverless functions at the edge, ensuring minimum latency from anywhere in the world.
Astrogoy
Founder · Development · Design
An independent project built with passion for astrology and technology. Every feature, every line of code, and every calculation algorithm is hand-written.
An independent project, built with intention
Astrogoy is a one-person project. Every design decision, every algorithm, and every word of the interface passes through the same filter: does it add real value to the user? The organization, vision, and judgement behind it all are what give the result its coherence.
State-of-the-art tools are part of the workflow, as they are for any modern professional. But a tool without direction builds nothing. What sets this project apart is applied knowledge: of astrology, of astronomy, of design, and of what the user truly needs.
That also means each user's feedback has direct weight in what gets built next.
