Questions & Answers

As answered by people managing Astro Engine and Postbox.

What makes your product unique?

Astro Engine's answer

Every calculation runs through Swiss Ephemeris in real time - the same astronomical engine used by research institutions, accurate to 0.001ยฐ. Most astrology apps use pre-computed tables or simplified math. We compute your exact planetary positions, aspects, and transits from raw astronomical data. No templates, no shortcuts. You also get features like birth time rectification (a 360-candidate scan) and Mercury Retrograde tracking precise to the second.

Why should a person choose your product over its competitors?

Astro Engine's answer

Precision and depth. Co-Star gives you a daily push notification. We give you a full astronomical blueprint 10 planets, 12 houses, every major and minor aspect, dignity analysis, and ongoing transit forecasts. All computed, not generated from generic templates. Plus it's available in 5 languages and works entirely in the browser no app install needed.

How would you describe the primary audience of your product?

Astro Engine's answer

People who take astrology seriously but want it grounded in real astronomy. They've outgrown daily horoscope apps and want to understand their full chart the aspects, the transits, the timing. Many are going through major life transitions and use astrology as a framework for self-understanding and decision-making.

What's the story behind your product?

Astro Engine's answer

I was frustrated that every astrology site either gave oversimplified Sun-sign horoscopes or charged premium prices for basic chart calculations that were sometimes wrong. I built Astro Engine to be the most accurate free birth chart calculator on the web, powered by the same Swiss Ephemeris library that professional astrologers and observatories use. It started as a calculator and grew into a full platform with compatibility analysis, daily forecasts, celebrity charts, and more.

Which are the primary technologies used for building your product?

Astro Engine's answer

Python (FastAPI) backend, Swiss Ephemeris (pyswisseph) for all astronomical calculations, PostgreSQL database, Docker for deployment, server-side rendering for SEO. The frontend uses vanilla JavaScript with no heavy framework pages load in under 200ms
