Kalmanas vs Co-Star
Co-Star made astrology social and beautifully designed. Kalmanas brings that same design sensibility to the deepest Vedic calculations available anywhere online.
TL;DR — Co-Star the social astrology pioneer — viral design, but zero Vedic depth. Kalmanas brings JHora-level Vedic depth with a modern dark-luxury interface, 100+ yogas, 19 divisional charts, and AI narratives grounded in classical texts — starting free with Pro at ₹199/mo.
Feature-by-Feature Comparison
| Category | Kalmanas | Co-Star |
|---|---|---|
| Astrological System | ★★★★★Vedic (sidereal) astrology with Lahiri ayanamsa default and 12 options. Rooted in Parashara, Jaimini, and Nadi traditions. | ★★★☆☆Western (tropical) astrology using Porphyry house system — a non-standard choice that many astrologers question. |
| Chart Depth | ★★★★★19 divisional charts, 100+ yogas, Shadbala, Ashtakavarga, Arudha Padas, Sphutas, Vimshottari Dasha with narrative timing. | ★★☆☆☆Basic natal chart with sign/house placements. No divisional charts, no yogas, no Dasha timing, no strength analysis. |
| Design & UX | ★★★★★Dark luxury aesthetic, mobile-first, Lighthouse 96. Focused on depth and clarity. | ★★★★★Iconic black-and-white minimalism. Beautiful social interface. But Lighthouse score is just 29. |
| AI Interpretation | ★★★★★AI narratives grounded in classical texts (BPHS, Saravali, Hora Sara). Explains why placements matter. | ★★★☆☆AI-generated notifications — often provocative or vague. No astrologers on staff. Criticized for harmful messaging. |
| Social Features | ★★☆☆☆Compatibility readings available. Shareable chart cards coming soon. No in-app social network. | ★★★★★Core feature — add friends, compare charts, shared daily updates. Social virality drives growth. |
| Performance | ★★★★★Lighthouse 96. Sub-second loads, self-hosted fonts, deferred analytics. | ★☆☆☆☆Lighthouse 29. Very slow loads due to heavy JavaScript and third-party scripts. |
Which One Is Right for You?
Choose Kalmanas if
You want serious Vedic astrological depth, psychological profiles backed by classical texts, and a self-knowledge tool — not a social app.
Choose Co-Star if
You want social astrology — comparing charts with friends, viral daily notifications, and a minimalist Western-astrology aesthetic.
Why People Switch from Co-Star
- No Vedic astrology at all — only Western tropical system
- Shallow analysis — basic sign/house placements without depth
- Provocative daily notifications criticised for harmful messaging
- No planetary strength, no timing (Dasha), no divisional charts
- Lighthouse score of 29 means painfully slow loads
