Prokerala vs Kundli.site: Accuracy & Features Compared (2026)

Direct answer: Prokerala is the established Vedic calculation suite with a public API popular among developers, covering panchang, kundli, and matching. kundli.site is the newer challenger built on a homegrown engine benchmarked to Swiss Ephemeris parity (≤0.005° deviation) with published verification. Choose Prokerala for API/developer needs; kundli.site for a free consumer chart with documented accuracy.

Prokerala has been the default "serious" Vedic calculation site for years — the one developers integrate and astrologers cross-check against. kundli.site is the new entrant whose entire pitch is verifiable accuracy. This comparison is factual, based on each product's public pages, and follows our comparison ground rules: no trash-talk, no invented stats, only verifiable claims.

Head-to-head table

Accuracy: reputation vs documentation

This is the real comparison, and it cuts in two directions.

Prokerala's case is reputation and adoption: it's the reference implementation many developers and astrologers cross-check against. Being the de facto standard that others verify against is a genuine, hard-earned signal — software that were systematically wrong wouldn't survive as everyone's second opinion.

kundli.site's case is documentation: instead of reputation, it publishes the test. Its engine was verified against the Swiss Ephemeris across 53 charts with planetary positions matching to ≤0.005° (about 18 arcseconds), covering nakshatras, dasha boundaries, navamsa, the 16 vargas, KP sub-lords, and house cusps. The verification methodology — including the 19 calculation bugs found and fixed during testing — is published rather than hidden. See how we verify our accuracy.

Neither side has published a head-to-head benchmark against the other, so any claim that one "beats" the other on raw math would be unverifiable — and we won't make it. What we can say: two engines that both implement Lahiri ayanamsa, correct whole-sign houses, and a proper ephemeris should agree on planetary positions to the arc-minute. Where they differ, one of them has a bug, and the published-test engine is the one you can audit.

Features: what each one actually gives you

Prokerala is the broader toolbox: panchang, muhurta, kundli, matching, plus the developer API that made it the infrastructure choice for apps that need Vedic calculations without building an engine. If you're building an app, Prokerala's API is the established answer in this niche.

kundli.site is the narrower, deeper consumer product: free chart generation with full positions, dashas, divisional charts and yoga detection, plus paid PDF life reports as one-time purchases (geo-priced — INR for India, CAD for Canada, USD elsewhere; never a subscription). It deliberately does not do consultations or APIs: it's a calculator and report generator, not a marketplace.

Pricing models

• Prokerala: free consumer tools; paid tiers for API/developer usage.
• kundli.site: free charts with no signup; reports are one-time purchases (you keep the PDF forever) with a 7-day money-back guarantee. No subscriptions, no card-on-file recurring billing — a deliberate choice after the FTC's June 2026 action against subscription-trap astrology apps (see our pricing-trap guide).

Which should you use?

• Building an app or need programmatic Vedic calculations? → Prokerala's API.
• Want a free, accurate chart with no signup and a documented engine? → kundli.site.
• Want both? Use both — generate the same chart on each and compare positions. Agreement to the arc-minute is exactly what correct implementations should produce, and it's the cheapest audit in astrology.

Frequently asked questions

Is Prokerala accurate?

Prokerala is widely used as a cross-check reference by developers and astrologers, which is strong reputational evidence. It does not publish a formal verification methodology on its consumer pages, so its accuracy case rests on adoption rather than documentation.

Is kundli.site accurate?

kundli.site publishes a verification methodology: a homegrown engine benchmarked against the Swiss Ephemeris across a 53-chart sweep, with planetary positions matching to ≤0.005° and dasha, varga, and house calculations all checked. The methodology page documents bugs found and fixed during testing.

Do Prokerala and kundli.site use the same ayanamsa?

Both use Lahiri (Chitrapaksha) as the default — the standard for Indian Vedic calculation. Charts generated on both with default settings should use the same sidereal reference.

Does Prokerala have an API?

Yes — Prokerala's public API for Vedic calculations is one of its main differentiators and is popular with developers. kundli.site does not offer a public API.

Which is free?

Both offer free chart tools. Prokerala's free tier is part of a broader free suite; kundli.site's free tier is a full chart with no signup required.

Can I use both to verify my chart?

Yes — and you should. Generate the same birth details on both with Lahiri settings and compare planetary positions. Correct implementations agree to the arc-minute; disagreement means a settings mismatch (ayanamsa, house system, timezone) or a bug.

Which is better for kundli matching?

Prokerala includes matching in its free suite and has the longer track record. kundli.site focuses on individual charts and reports; for matching-specific depth, also consider AstroSage's matching tools.

Does kundli.site sell subscriptions?

No. Reports are one-time purchases with a 7-day money-back guarantee. There is no subscription product and no recurring billing.
