Free kundli websites, compared honestly

AstroSage, Drik Panchang, Prokerala and this site. What each is genuinely good at, including where the others beat us.

Where each one is strongest

AstroSage
The widest reach of any of them: many more Indian languages than we support, a mature mobile app, and a very large body of article content. If you want an app and your language is not one of our three, this is the straightforward answer.
Drik Panchang
The deepest calendrical detail anywhere - festivals, vrats, regional variations and muhurat tables we do not attempt. If you need a panchang for a specific tradition or an obscure observance, go there. Note that it computes sunrise with the upper limb and refraction, where we and Prokerala use the disc centre: times can differ by a few minutes, and neither is wrong.
Prokerala
A very broad set of calculators covering more ground than ours, and a clean presentation. Its panchang uses the same sunrise convention we do, so its times and ours agree closely.
RashiKundli
Three languages done properly rather than many done thinly, every number from the Swiss Ephemeris with the method stated on the page, no AI anywhere in a calculation, and no fear-selling: the dosha pages tell you what a configuration is and sell nothing against it. The free PDF is the whole calculation, not a teaser.

What we do not claim

We have not measured their accuracy against ours across a large sample, so this page makes no accuracy claim about them. Where we have compared - the panchang - we published the result including the four-minute sunrise difference with Drik, which is a convention difference and not an error on either side.

We are smaller than all three and newer than all three. If you want the broadest feature set or the most languages, we are not it.
