Evidently
Evidently is an open-source Python framework for ML and LLM observability. It provides over 100 metrics to evaluate, test, and monitor AI-powered systems and data pipelines, covering both tabular data and generative AI applications. The framework generates interactive reports and test suites that can be used for debugging, validation, and ongoing monitoring. It detects data drift, model performance degradation, and quality issues in LLM outputs, helping teams maintain reliable AI systems. Evidently integrates easily into Python workflows, including Jupyter notebooks, CI/CD pipelines, and production monitoring stacks. It is designed for data scientists and ML engineers who need observability without heavy infrastructure.
