    Tools list

    Collate

    Managed agentic data platform built on OpenMetadata, with AI agents, data quality tests, observability metrics, column-level lineage, and governance workflows.

    My Opinion

    Best for data teams that want OpenMetadata fully managed, with enterprise support, security features, and advanced governance workflows.

    OpenMetadata

    Open-source context platform that unifies metadata for humans and AI agents, with data discovery, data quality tests, column-level lineage, and governance.

    My Opinion

    Best for data teams that want one self-hosted, open-source platform for discovery, data quality, and governance with a wide range of integrations.

    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.

    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.

    Great Expectations

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

    OSStestingpython-native
    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.
