Best for Automates testing with cross-browser coverage and synthetic monitoring.

When not When you need manual testing or security assessments.

Great Expectations is an open Python library for data quality testing and documentation. Write expectations declaratively (expect table to have 1M rows, column X in range 0-100). GX automatically tests incoming data and blocks pipelines if quality degrades. Profiles generate expectations from sample data. Cloud version adds UI for expectation management and anomaly alerts. Backed by Accel Partners.
