Compare
Kriya, side by side with Prokerala.
We're asked this often, so: here's the honest comparison. We cite our own numbers; we mark Prokerala's as “not publicly documented” where we couldn't find equivalent disclosure. Verify everything against the vendor's own docs before you commit.
Comparison
The dimensions developers care about.
Endpoint count is just the start.
Last reviewed against publicly accessible Prokerala documentation: April 2026. We re-verify on each Kriya release. Spot something out of date? — admin@insightsbyomkar.com.
Why it matters
No black box.
Most astrology APIs run on Swiss Ephemeris under the hood — a fine library with a copyleft license that quietly limits what you can build downstream. Their accuracy claim is a third-party assertion. Their algorithmic choices are invisible.
Kriya is computed from first principles. The full coefficient sets — VSOP87D from IMCCE, ELP/MPP02 from Chapront & Francou, DOPRI8 8(7) from Hairer & Wanner — live in the engine. Every residual against JPL Horizons is public on /accuracy. The Moon-ceiling document publishes the one residual we can't close — and the two multi-week paths that would close it. The doctrine attributions live in SOURCES.md: pre-1929 public-domain only, every traditional rule traced to its primary source.
That posture is a moat against the day a customer asks “where exactly does this number come from?” — it's also the reason we can ship a permissively-licensed SDK in three languages. The MIT license on kriya-astrology means your downstream product isn't legally entangled with ours.
When the other vendor wins
When to pick Prokerala instead.
Honest selling means saying when you're not the right answer. Pick Prokerala if:
- You need an established Indian-market vendor with a decade-long track record and you're willing to trade algorithmic transparency for vendor longevity.
- You've already standardized on their endpoints in production and the migration cost is higher than the accuracy / SDK / pricing delta.
- You need a feature we don't have yet — check our public API reference first; it's rare, and we ship fast.
For everything else — accuracy posture, transparency, modern SDKs, async jobs, LLM-grounded interpretation, pricing per call — the math comes out our way.
