Four charts show what competitors ship, where that depth lives, what they charge and which engine
sits underneath.
1. At a glance
The market splits by tradition. Western apps sell engagement; Vedic apps sell consultations,
reports and remedies.
Nebula leads U.S. revenue at ~$50M ARR (2023) by bundling tarot, palmistry and psychic chat.
Co-Star holds 30M+ downloads.
AstroSage claims 70M+ downloads and ~80% of India’s kundli market. AstroTalk runs a
marketplace of 1,600+ verified astrologers.
Only AskSoma and Astro-Seek (via AstroAPI) ship a developer API.
Professional calculation consolidates on Swiss Ephemeris (AGPL-3.0 or CHF 700 commercial).
XALEN, Roxy Ephemeris and direct JPL DE440 avoid that licence.
2. Feature coverage per app
Western apps cluster at natal, transits, synastry and AI chat. Only two of seven add progressions
or returns, and none covers Vedic vargas or dasha.
Vedic apps cluster at vargas, dasha and panchang. Only AstroSage and Astro-Seek reach the full
16-chart Shodashvarga set.
Astro-Seek is the only app spanning both traditions and exposing an API; AskSoma is the only
Vedic-first app with one.
A hollow mark means absent or undocumented: vendors publish feature lists, not matrices.
3. The features, in one line
Term
What it means
Natal chart
Planets, houses and angles at the moment and place of birth.
Transit
Where planets are now, measured against the birth chart.
Secondary progression
One day after birth mapped to one year of life; solar arc is a related method.
Solar / lunar return
Chart cast when the Sun or Moon returns to its birth position; a yearly or monthly forecast.
Synastry / composite
Two charts compared (synastry) or merged into one (composite); the relationship view.
Divisional chart (varga)
A Vedic chart derived by dividing each sign — D9 for marriage, D10 for career, up to D60.
Dasha
Vedic planetary period system used for timing; Vimshottari is the common 120-year cycle.
Panchang
Daily Hindu almanac: tithi, nakshatra, yoga, karana and vara.
Muhurta
An auspicious window chosen for one event, such as a wedding or a launch.
Shadbala
Six-fold planetary strength score used to rank a chart’s planets.
Ashtakavarga
Point system scoring how supportive each sign is for each planet.
MCP
Model Context Protocol — a standard way to expose tools and data to AI agents.
4. Where the depth lives
Desktop wins on Western technique. Wheel editing, harmonics, Zodiacal Releasing, Firdaria,
fixed stars and hundreds of minor bodies appear only in desktop software such as AstroGold
Professional, Parashara’s Light and Jagannatha Hora.
Mobile wins on reach, not depth. No app matches its own desktop edition; returns, stations,
harmonics and the wheel editor are stripped.
APIs win on Vedic breadth. D1–D60 vargas, 100+ yogas, 20–30 languages, white-label reports and
MCP tooling exist only here.
Desktop is bought, not rented. Kala costs $254.95; suites run $299–360 perpetual against a
$7–15/mo consumer norm.
The empty top-right cell is the opening: no tier serves advanced Western and advanced Vedic
work in one product.

Western pricing is flat: $7–15/mo buys the paid tier almost everywhere. Nebula is the outlier
because it sells minutes, not software.
Vedic leaders keep the app free and monetise trust through consultations, reports and remedies.
Pay-per-question (₹49) is the newest experiment.

—
n/a
¹ AGPL-3.0 or CHF 700 commercial licence, unless the vendor holds a commercial licence; some
vendors do not publish which.
Licensing is the hidden decision. Six of the nine hosted providers listed wrap Swiss
Ephemeris. Only Vedika (Apache-2.0), RoxyAPI (MIT) and OpenEphemeris (commercial API over DE440)
avoid it.
MCP is the new integration surface. Four of the nine run an MCP server: AstrologyAPI
(109 tools), OpenEphemeris (92), Vedika (36) and RoxyAPI (18 domain servers). Astrology-API.io
and VedicAstroAPI also list support.
White-label delivery is an API feature. Branded PDF reports and 20–30 language coverage exist
only here; no mobile app offers either.
7. What it means for our build
Licence an API to reach market fastest, and accept margin compression at scale.
Own the engine with Swiss Ephemeris (CHF 700) or a permissive alternative (XALEN, Roxy
Ephemeris) for calculation sovereignty and full feature control.
Take the vacant hybrid tier: one app and one API with professional-grade Western and Vedic
calculation, AI synthesis, cross-tradition views and a typed MCP surface. No competitor occupies
it.
Method: vendor pricing pages, app-store listings and public feature tables, collected October 2026.
