    Data Testing Tools for Prefect

    Great Expectations

    Open-source Python data quality framework, stewarded by Fivetran, with 50+ declarative expectations to validate files, SQL databases, warehouses, and DataFrames.

    My Opinion

    Best for Python data engineers who want a free, code-first testing library and don't need a managed UI, since GX Cloud is no longer available.

    Data Observability Tools for Prefect

    Monte Carlo

    Data + AI observability platform that monitors data pipelines and AI agents in production, with column-level lineage and AI troubleshooting agents.

    My Opinion

    Best for large data teams ready to invest in a mature, widely adopted platform that monitors both their data and their AI agents.

    Elementary OSS

    Open-source dbt package by Boomi that adds anomaly detection tests and a CLI-generated data observability report to dbt projects.

    My Opinion

    Best for dbt teams that want free anomaly detection tests inside their existing dbt project, without a cloud account.

    Unified Data Quality Tools for Prefect

    Elementary Cloud

    Data & AI control plane by Boomi with anomaly detection monitors, column-level lineage, incident management, a data catalog, and AI agents.

    My Opinion

    Best for dbt-centric analytics teams that want managed monitoring, lineage, and AI agents for triage on top of their dbt tests.
