## AI interpretation — verify before relying

Great Expectations is a data validation and quality framework that lets you define, test, and document data expectations as expressive unit tests, then automatically generate validation reports.

Verdict: Great Expectations is a mature, actively maintained data validation framework with no known vulnerabilities. Its permissive Apache-2.0 license and low install friction make it suitable for production data quality workflows. The 18 runtime dependencies are well-established libraries (pandas, numpy, pydantic, jsonschema, etc.), supporting common data science and validation tasks.
