A powerful, flexible data quality solution

Understand what to expect from your data with the most popular data quality framework in the world: GX Core is the engine of the GX data quality platform.

Have confidence in your data

Get started quickly

Use GX Core with tools you’re already familiar with, like Python and Jupyter notebook. Its minimal technical prerequisites mean maximum readiness for use.

Jump in with confidence.
