What it does

Key features

  • Data drift detection with 10+ statistical tests (KS, PSI, Wasserstein, Jensen-Shannon)
  • Model performance monitoring: classification, regression, and ranking metrics
  • Data quality tests: missing values, range violations, distribution checks
  • HTML report generation for shareable APAC offline analysis
  • Live monitoring dashboard for real-time APAC production visibility
  • MLflow and W&B integration for unified APAC ML observability
When to reach for it

Best for

  • APAC ML engineering teams who need open-source data drift detection and model performance monitoring integrated into batch pipelines, with shareable reports for APAC stakeholder communication.
Don't get burned

Limitations to know

  • ! Requires ground truth labels for model performance monitoring (not estimation)
  • ! Live dashboard is newer and less mature than the batch report functionality
  • ! Large-scale streaming APAC monitoring requires custom integration work
Context

About Evidently

Evidently is an open-source Python library for ML model monitoring and data validation. APAC ML engineering teams use Evidently to detect data drift, monitor model performance, and run data quality checks across their production ML pipelines — generating shareable HTML reports for offline analysis and live dashboards for real-time APAC production monitoring.

Evidently's report and test suite architecture allows APAC teams to run systematic checks on tabular data, text data, and ML model outputs. Data drift tests check whether the statistical distribution of APAC input features has shifted between training (reference) and production (current) datasets. Model quality tests check classification metrics (accuracy, precision, recall, F1), regression metrics (MAE, RMSE), and ranking metrics — flagging when APAC production model performance degrades below configured thresholds.

APAC teams integrate Evidently into batch monitoring pipelines: after each day's APAC production predictions are collected, Evidently runs a suite of drift and quality tests, generates a report, and raises alerts if thresholds are breached. The library integrates with MLflow and Weights & Biases for logging monitoring results alongside APAC training experiments — providing a unified view of model health from training through production.
