Elementary vs Metaplane

Quick verdict

Elementary OSS has two parts: a dbt package that stores run and test results in an Elementary schema in your warehouse and provides anomaly detection as native dbt tests (volume, freshness, column metrics and schema changes), and a Python CLI that builds a self-hosted observability report and sends alerts to Slack or Microsoft Teams. The documentation says OSS covers a single dbt project. Elementary Cloud is the managed service: it covers several dbt projects, can connect a warehouse without dbt, and adds ML-powered anomaly detection, column-level lineage, a catalog, incident management and AI agents.

Metaplane connects to the warehouse, the transformation layer and BI tools, and places machine learning monitors on tables for row counts, freshness and column statistics such as mean and standard deviation, with custom SQL monitors for business rules. End-to-end lineage (including Looker through LookML Git integration) shows which dashboards a problem reaches, and Data CI/CD previews the data impact of dbt changes on GitHub or GitLab pull requests. Datadog announced the acquisition on 23 April 2025; Metaplane said it would continue as a standalone product branded "Metaplane by Datadog", and on 7 November 2026 metaplane.dev still sold its own plans.

Side by side

Key differences

Monitoring inside dbt versus monitoring from outside

Elementary lives in your dbt project. You add the package, then declare tests in YAML beside the models, and they run with dbt test or dbt build like any other test. A minimal example:

# dbt schema.yml with Elementary tests
models:
  - name: fct_orders
    data_tests:
      - elementary.volume_anomalies
      - elementary.freshness_anomalies:
          arguments:
            timestamp_column: updated_at
      - elementary.schema_changes

The upside is that monitoring is reviewed, versioned and deployed with the models; the downside is that OSS sees only what dbt manages, in one project. Metaplane connects to the warehouse directly and places monitors itself, so tables that dbt does not build (raw loads from Fivetran or Airbyte, for example) are covered without changing code, and it adds dbt and BI metadata through integrations. Elementary Cloud closes much of this gap, at a price.

What you get for free

Elementary OSS is free under Apache 2.0, with anomaly and schema tests, a self-hosted HTML report and Slack or Teams alerts. There is no table limit in the licence, but you host the report and run the CLI yourself, and it covers one dbt project. Metaplane Free is "free forever" with no credit card, and covers 10 monitored tables and 3 custom SQL monitors, hosted for you. A monitored table is one with monitors active for more than 30 days; synced tables without monitors do not count. In short: Elementary gives more coverage at no cost if you do the operations work; Metaplane gives less coverage at no cost with no operations work.

Lineage and pull request previews

Metaplane leans on end-to-end lineage: warehouse, dbt and BI tools such as Looker, Tableau, Power BI, Sigma, Mode, Metabase and Hex, so an incident can be traced to the dashboards it reaches. Its Data CI/CD feature comments on GitHub and GitLab pull requests with the downstream data impact of a dbt change. Elementary OSS shows dbt lineage and test history in its report; column-level lineage and wider catalog features are part of Elementary Cloud. If BI-level impact analysis is a requirement on day one, Metaplane offers it in the hosted product; with Elementary you need Cloud for the equivalent depth.

Ownership and roadmap

Metaplane belongs to Datadog. The acquisition announcement said existing customers would see no change for now, that the product would continue standalone, and that Datadog planned to connect data quality to products such as Data Streams Monitoring, Data Jobs Monitoring and APM. Datadog also documents its own Data Observability Quality Monitoring inside the Datadog platform. That can be an advantage if you already run Datadog, but it is a roadmap question to ask before a long contract. Elementary is independent, and its pricing page notes that if you stop a Cloud subscription you can continue on the self-hosted community version, which limits lock-in.

Pricing and licensing

Elementary. Elementary OSS is free under Apache 2.0. Elementary Cloud lists Scale (up to 10 editor seats and up to 1,000 tables), Enterprise (up to 20 editor and 40 viewer seats, up to 3,000 tables, SSO and RBAC) and Unlimited (unlimited seats, up to 3,000 tables, dedicated customer success engineer), plus an AI Layer add-on billed in credits. Pricing is based on seats and environments, extra tables are priced per 1,000, and every plan says "Talk to us" with no amounts. A 30-day trial is offered; the page says it includes all features of an "Essentials" plan, a name not among the listed plans.

Metaplane. metaplane.dev/pricing lists Free at $0 (10 monitored tables, 3 custom SQL monitors, no credit card), Pro (usage-based, no rate shown; the plan card lists up to 100 monitored tables) and Enterprise (custom, unlimited tables, SSO and AWS or Azure PrivateLink). Paid plans are billed per monitored table and are chosen after a 14-day period; Snowflake customers can pay with Snowflake credits. User allowances are listed inconsistently on the page (for example Free shows 4 users on the plan card and 1 in the comparison table), so confirm seats with the vendor.

Pricing checked on the vendors' official pages on 7 November 2026. Prices change; confirm before buying.

Where each one leads

Limitations

When to choose each

When neither is right

• You need enterprise-wide observability with dedicated instances or legacy warehouse coverage: see Monte Carlo vs Bigeye.
• You only need assertions on keys and values: dbt data tests are already in your project; see Datafold vs dbt tests.
• Your pipelines are Python or Spark rather than dbt: see Soda vs Great Expectations.
• You want database performance monitoring rather than data quality: see Database monitoring vs APM.
