The astrology engine behind our client websites.
The Zumper Astrology Engine is the calculation layer Zumper Innovation Labs builds into websites for astrologers, numerologists, Vastu consultants and the platforms that serve them: kundli and divisional charts, Guna Milan, dasha timelines, numerology and Lo Shu, daily Rashifal and Panchang. It ships as on-site tools, branded reports, APIs and consultant dashboards, and eight of its tools run free on this domain so you can test the maths before buying any of it.
Also open right now: the same engine on a demo website at demo-astro.zumper.in.
Which tools are already built?
Eight, and they are the ones a seeker arrives asking for. This is astrology software for astrologers who want the maths running on their own domain. Anything past this list sits on the build menu further down, priced as work instead of presented as something already sitting on a shelf.
Kundli Generator
Birth chart with divisional charts and planetary positions.
Guna Milan
36-point Ashtakoota marriage compatibility score.

Daily Panchang
Tithi, Nakshatra, Yoga, Karana and Muhurta.

Open them on our free tools page or on the demo website. A shareable result is a lead that names you, which is why the output carries your brand on a client site, not ours.
How does the engine reach your clients?
Four shapes, chosen by what your practice already has. A solo consultant answering one number and a platform with its own front end need very different pieces of the same engine.
Free tools on your own site
The calculator runs inside your website, on your domain, styled to your brand, with your contact details on the result. Visitors use it; you get the birth details that make a consultation worth booking.
Branded reports
Chart PDFs and written remedy reads come out of one custom-branded generation engine, billed once per build however many reports use it.
APIs into an existing product
The same calculations delivered as endpoints for a platform that already has its own front end, its own users and its own database.
Consultant dashboards
Saved client charts, follow-up history and a reader or consultant area for a practice with more than one person reading.
API and integration work is described on its own page: astrology software development.
What is in the 190-module catalogue?
190 numbered modules across eight groups, each with its own indicative price band, assembled from the scoping document this practice works from. It is a menu, not an inventory: the modules are engineered into a build when you order them.
Two rules keep the quote honest. Modules that share one underlying calculation engine are charged once, not once per name. And the branded PDF generation engine is billed once per build however many reports use it, because it is one piece of engineering whatever sits on top of it.
Astrology
Birth charts, dasha and transit, marriage matching and specialised analysis.
Numerology
Core number calculators plus Lo Shu, Chaldean and Pythagorean systems.
Vastu
Residential, commercial and directional analysis up to automated layout engines.
Gemstone, Rudraksha & Remedies
Recommendation engines, guidance and written remedy reports.
Panchang & Muhurat
Calendar maths, auspicious-window finders and festival data.
Consultation & Booking
Appointments, slots, payments and consultant management.
AI-Powered Tools
Generated interpretation, where the model and API usage are always billed separately.
Other Spiritual Niches
Tarot, name tools, pujas, stores and membership systems.
The base build is the Custom Website with Advanced Tools plan from ₹24,999, which includes exactly eight tools chosen by you, and every module beyond that carries its own band. Select them and read the arithmetic in the astrology website cost calculator.

Astrology engine questions
What is the Zumper Astrology Engine?
One calculation engine behind the astrology, numerology and Vastu tools we ship to practitioners: kundli and divisional charts, Guna Milan, Vimshottari dasha periods, numerology and Lo Shu, daily Rashifal, Panchang and muhurat timings. It runs as on-site tools, as reports, as APIs and inside consultant dashboards, and it carries your brand rather than ours.
Can I try it before buying?
Yes. Eight tools run free on this domain and on our demo build: kundli, Guna Milan, numerology, Lo Shu, dasha timeline, Rashifal, Panchang and marriage prediction. They are the same calculations your visitors would run, so you are testing the maths rather than a screenshot of it.
Is the 190-module catalogue a list of ready-made tools?
No, and this is the sentence to read before a quote surprises you. The catalogue is a build menu: 190 modules with indicative price bands, each scoped and developed as part of a build. The eight tools on the demo are developed and running today; the rest of the menu is priced work, ordered with you.
How is it priced?
Each module carries its own indicative band, and the cost calculator prices your selection against a base build rather than handing you a vague estimate. Modules that share one underlying calculation engine are charged once, and the branded PDF engine is billed once per build no matter how many reports use it. AI-generated interpretation always bills model usage separately.
Are the predictions accurate?
The charts and numbers are computed from the birth details entered, using standard Vedic calculations and a sound ephemeris. That is a claim about arithmetic, not about fortune: no honest developer can guarantee a predictive outcome, and we do not offer one.
Can the engine be added to a website we already run?
Yes. Kundli, matching, numerology and Panchang ship as integrations into an existing site or product without rebuilding it, either as embedded tools or as APIs your current front end calls. That delivery is scoped on the astrology software development page.
