CosmyDay VS Code Effects

CosmyDay's answer

CosmyDay computes everything from real astronomical data instead of serving pre-written zodiac filler.

Swiss Ephemeris under the hood — the same ephemeris professional astrologers use. Tropical zodiac, Placidus houses, Whole Sign fallback above 66° latitude. 14 bodies including North/South Node, Chiron and Lilith. Horoscopes generated from the actual sky — each daily, weekly and monthly forecast is built from the real transits for that period, then written in plain English. Nothing is recycled from last year. No account, ever — no registration, no password, no app. Enter birth date, time and place and get the result. Data is cached in your browser so you don't retype it. Shareable chart links — send a natal chart or compatibility result to someone and they see it instantly, without signing up either. Free means free — the calculators and horoscopes aren't a trial. Paid reports are optional one-time purchases with no subscription and no auto-renewal.

CosmyDay's answer

Most astrology apps ask for an account, an install and a recurring subscription before showing you anything meaningful. CosmyDay inverts that.

Accuracy you can check. Many free astrology sites approximate house cusps or skip minor bodies entirely. CosmyDay runs full Swiss Ephemeris calculations with standard aspect orbs — conjunction 8°, sextile 6°, square 7°, trine 8°, opposition 8°. Zero friction. No signup wall, no email gate on the calculators, no push-notification nag. Honest billing. The astrology app category is full of $9.99/week auto-renewing traps. CosmyDay sells one-time reports ($19.90–$29.00) delivered as PDFs. Nothing renews. Interpretation, not just a chart image. Free calculators explain what each placement and aspect actually means, rather than dumping a wheel and upselling the explanation. Depth for the curious. 120 planet-in-sign guides, 78 compatibility pairings plus gender variants, and a rolling monthly horoscope archive — usable as a reference library, not just a one-visit toy.

CosmyDay's answer

English-speaking readers in the US, UK, Canada and Australia — predominantly women aged 20–45, with strongest engagement in the 25–35 range.

They fall into three overlapping groups:

Relationship-curious — arrive via compatibility and synastry, usually after meeting someone new or trying to make sense of an existing dynamic. Self-understanding seekers — arrive via natal chart, treating astrology as a reflective framework rather than literal prediction. Overlaps heavily with journaling, therapy and personal-development audiences. Daily-ritual readers — check a horoscope as part of a morning routine, low-commitment and high-frequency.

Skew toward mobile, social-first discovery (TikTok, Pinterest, Instagram), and people who consider astrology meaningful-but-not-dogmatic — a lens for thinking, not a religion.

CosmyDay's answer

CosmyDay started as a technical frustration. Nearly every free astrology site online either produced sloppy calculations or wrapped decent math in a subscription funnel that demanded a card before showing anything useful.

The premise was simple: if the ephemeris math is done properly and the interpretations are written clearly, the free tools should be genuinely good on their own — and people who want depth will pay for a report because they want it, not because a paywall trapped them.

The engine was first built and validated on a Russian-language sister project, where real users proved that people care far more about their own natal chart than about generic sign content. CosmyDay is the rebuilt English-language version of that engine, with a cleaner architecture and a US-focused content library.

It remains an independent, self-funded project run by a small team, with no investors and no ad networks shaping what gets published.

CosmyDay's answer

Frontend: Next.js (App Router) with TypeScript and React, statically generated and deployed on Vercel. ~500 pre-rendered pages plus on-demand ISR for the horoscope archive. Backend: Python with FastAPI, running on a dedicated Hetzner server behind systemd. Astronomy engine: Swiss Ephemeris via pyswisseph — all chart, transit and synastry math. Content generation: LLM-assisted interpretation writing on top of computed sky data, with an automated validation layer checking word count, jargon and temporal accuracy before anything is published. Data: SQLite for orders and subscribers; JSON content files baked into the frontend at build time. Payments & delivery: PayPal REST API; transactional email via Resend; PDF report generation server-side. Analytics & indexing: Google Analytics 4, IndexNow for near-instant search-engine indexing, MaxMind GeoLite2 for country-level traffic enrichment.

CosmyDay's answer

CosmyDay is a direct-to-consumer product, not B2B — there are no enterprise accounts or named clients to list. Customers are individual readers buying personalized reports for themselves or as gifts.

If SaaSHub requires a non-empty answer here, that paragraph is the safest thing to submit; leaving it blank is also fine and won't hurt the listing. Verify the team-size wording in #4 against how you want to present the project publicly.
