Hi Product Hunt, We're CosmosDaily Astrocartography is the astrology of place. Every planet in your birth chart draws a line across the Earth, and the cities on those lines are where that planet's themes show up strongest in your life. It's a beautiful idea, but it's oddly hard to access: the serious tools are expensive desktop software, and most free ones are too rough to trust. Closing that gap is what I wanted to do, so I built a free map that's actually accurate. Every line is cross-checked against the VSOP87 ephemeris, placed to within about a mile, the same standard the paid software uses. It has parans, local space, a relocation compass, life-domain lenses (love, career, study, and more), and a "how to read this" guide for beginners. No sign-up, and it all runs in your browser. Honestly, the hardest part was the math, not the features. I spent most of the build validating positions against an independent reference, because a beautiful map with wrong lines is worse than useless to anyone who actually knows the technique. When it loads, it shows the chart of Jim Lewis, the astrologer who invented astrocartography in the 1970s. It felt right to open on his map. Swap in your own birth details and it redraws instantly. I'd love your feedback, especially from anyone who knows astrocartography and can check the lines against what they expect. What would make it more useful to you? Try it:
