NRIs comparing free kundli tools, including well-known names like AstroSage, often end up choosing based on which site looks more polished rather than which one is actually computing the chart correctly for a birth outside India. A short technical checklist is more useful than a general reputation comparison.
Questions worth asking any tool, including this one
- Which ephemeris does it use? This site computes positions with a high-precision astronomical ephemeris. Ask the same question of any tool you are considering.
- Which ayanamsa, and is it stated? This site uses Lahiri ayanamsa, the most widely used standard in India. A tool that does not disclose its ayanamsa makes it hard to know why two tools might disagree on a placement.
- Does it handle historical time zones and DST correctly for foreign cities? This matters specifically for NRI users: a birth in a US, UK or Gulf city needs the correct historical daylight-saving rule for that exact date, not just today’s rule. This site uses IANA timezone data (
tzdata) for this. - Does global city search work well, or is it India-focused? Some tools list Indian cities exhaustively but handle foreign cities poorly (missing smaller towns, wrong coordinates). This site uses open geocoding search that covers any city worldwide.
Why this matters more for a foreign birth
A birth in a major Indian city is a well-tested case for almost any tool. A birth in a smaller US or UK town, especially one whose time zone rules changed decades ago, is a much better stress test of whether a tool’s underlying computation is actually careful.
Run the comparison yourself
Enter the same birth details on the kundli tool here and on any other tool you are evaluating, and check whether rashi, nakshatra and lagna agree. If they do not, ask both tools which ephemeris and ayanamsa they used before assuming either one is wrong.
