RISING
Where is the demand coming from?
Leans on the founder
The founder's audience is a large part of it. This is the read that decides whether the traction would transfer to you.
Roughly what does it earn?
Not disclosedNo basis to estimate
We do not publish a figure until we have something to base it on. When we do, the method that produced it is shown alongside the range.
Could you build it?
Yes, in about 8 days
Nothing patented, no network effect, and no proprietary data set standing in the way.

What it is

A Python-based programmatic SEO generator that produces 21,000+ static astrology content pages (daily horoscopes, zodiac guides, planetary aspects) using Swiss Ephemeris data, open-sourced on GitHub. The project appears designed to power search-driven traffic for astrology SaaS; it received minimal traction with 1 HN point on launch.

The one thing to knowZero monetization evidence, no founder signal, and a single HN point suggest this is either a tool for the founder's own tianji-astrology.com or an unclaimed/dormant OSS project, making fast-follow risk low but organic demand uncertain.
