What is orrery?

Orrery is a fully client-side TypeScript calculator that generates Saju Palja four pillars, Ziwei Doushu fate plates, and Western natal charts directly in the browser—no servers or APIs needed. Drop in a birth date, time, and location, and it spits out detailed outputs like 60 Ganzhi pillars, Daewoon luck cycles, Mingban grids with 14 main stars and Sihua transformations, plus Swiss Ephemeris-based planet positions, houses, and aspects. Built with React and Vite, it delivers interactive wheels, tables, and exportable text for AI agents, solving the hassle of backend-heavy astrology tools.

Why is it gaining traction?

It stands out by packing three astrology systems into a single, zero-dependency npm package (@orrery/core) that devs can drop into any app, unlike clunky server-based alternatives or orrery modell kits requiring manual setup. The pure TypeScript ephemeris and lunar calendar conversions enable instant, accurate charts on any device, with mobile-responsive UIs and city search (Korean-focused, global coverage). Early adopters praise the dev server speed and text-copy for prompts, making it a quick win for orrery calendar prototypes.

Who should use this?

Astrology SaaS builders targeting East Asian users need Saju/Ziwei alongside Western charts without hosting costs. Frontend devs crafting fortune apps or personal dashboards will love embedding the core library for birth inputs and visualizations. Researchers porting traditional Perl/PHP 만세력 to modern web can start here for orrery deutsch or orrery london timezone handling.

Verdict

Grab @orrery/core for rapid astrology prototypes—it's functional and embeddable, with solid docs and examples. At 46 stars and 1.0% credibility, verify outputs against pro tools before production, but the AGPL license and live demo make it low-risk to test.
