Evidently Open-Source

An open-source framework to evaluate, test and monitor ML models in production. Prevent incidents, build trust, and make continuous improvements.


What's in there

Evidently has three components. You can start with minimal effort and one-off checks. As you scale, move to a complete monitoring stack with a self-hosted dashboard.

Evidently Reports

Evidently Reports

Visualize your models and data with rich interactive reports.

Evidently Test Suites

Evidently Test Suites

Run data and ML model checks for production pipelines and CI/CD.

Evidently ML Monitoring

Evidently ML Monitoring

Get a central dashboard to track the health of ML models and datasets.

When to use Evidently

Across the ML model lifecycle. Before deployment, validate your models and data with Reports and Test Suites. In production, gain visibility with Evidently ML Monitoring.

Evidently ML observability platform

What you can evaluate 

Hundreds of checks. From counting nulls in data to detecting embedding drift.

Why Evidently


  • Your data is yours. You can run Evidently on your infrastructure.
  • No vendor lock-in.
  • No black boxes. You can inspect the entire source code on GitHub.

Fits into any stack

  • Run wherever you run Python.
  • Add to the existing models, workflows, and infrastructure.
  • Batch or real-time. Text or tabular. Cloud or local. Pytorch or Scikit-learn. And anything else!

Start fast, tweak anything

  • Be as hands-off or hands-on as you like.
  • Start with presets and automated thresholds.
  • Customize metrics, dashboards, and test conditions as you go.

Pick metrics, not write them

  • 100+ useful checks and metrics out of the box.
  • In-built visualizations and parameters to tweak.
  • An ever-growing set of metrics, with an option to add yours.

One tool for ML reliability

  • One API to learn and tool to configure.
  • Evaluate drift or accuracy the same way each time.
  • Easily switch from monitoring to debugging.


  • Use only what you need.
  • Get going with reports, and switch to complete monitoring setup once ready.
  • Modular architecture. You can extend and build upon it.

Yes, it's open-source!

With a lot of examples in the docs.


Get started

Easily add Evidently to existing workflows, no matter where you deploy. 

Evidently Cloud

Evidently Cloud is the easiest way to get ML monitoring up and running.
