The world's most advanced analytics engine for NoSQL data is now 100% open source!

Modern APIs and apps don't speak in flat, tabular data. They speak JSON.

Precog is the analytics engine that natively handles JSON. It's easy for developers to integrate and comes with a high-level tool called Labcoat that lets data scientists and analysts deeply analyze their data.
