Monte Carlo is a commercial data observability platform: it monitors tables automatically rather than waiting for hand-written tests, enriches alerts with lineage and root-cause context, and routes incidents through triage workflows.
SaaS connected outbound to your sources; an optional agent runs as a Lambda, Cloud Run service, or Azure Function, and record-level samples can stay in your own object storage. Circuit breakers let a rule halt an Airflow DAG; alerts route by domain and ownership to Slack, Teams, PagerDuty, and Jira.
How Monte Carlo answers the questions Data Quality turns on.
| How it works | |
| Authoring model | Mostly the vendor's: out-of-the-box ML monitors for freshness, volume and schema arrive covering every table with nobody writing anything, and what a user authors sits on top: ML-based field health, dimension tracking and JSON schema, or rules-based SQL, field quality, referential integrity and comparison. Monitors as Code declares any of it in YAML through the CLI and a CI/CD pipeline |
| Detection model | Learned baselines by default, declared rules by exception, the out-of-the-box monitors run hourly over table metadata and flag deviations nobody specified, custom ML monitors learn field-level behaviour on a schedule you set, and the rules-based monitors do exactly and only what was written |
| Built-in monitors | Three families: out-of-the-box ML monitors for freshness, volume and schema change, hourly across every table; custom ML monitors for field health, dimension tracking and JSON schema on your own schedule; and rules-based monitors for SQL, field quality, referential integrity and comparisons, which use no ML at all |
| Prevention or detection | Detection by default, prevention on request, monitors run on schedules against data that has already landed, but circuit breakers let a rule halt a pipeline, with the Airflow provider triggering a rule, polling it and raising an AirflowFailException on breach. It fails open by default, so evaluation errors do not stop the DAG and only a genuine breach does |
| Lineage | Automatic and field-level, and half the product rather than a side feature, impact analysis names the downstream models, dashboards and consumers a break reaches, and root-cause insights are assembled from query logs, lineage and table contents to say where to look first |
| Alerts and delivery | Slack, Microsoft Teams, PagerDuty, Opsgenie, Jira and email, routed by domain and asset rather than poured into one channel, so an alert reaches the team that owns the table |
| Incidents and ownership | The strongest answer in this capability, incidents carrying routing, triage and workflow rather than a message someone has to notice, ownership attached to assets, and automated root-cause insights inside the incident itself |
| Running it | |
| What you run | SaaS connected outbound to your sources, with the platform, UI and monitoring always in Monte Carlo's cloud. Two variants move pieces into your environment (the Data Store holding record-level samples can sit in your own S3, GCS or Azure blob storage, and the Agent bridging to your sources can run as a Lambda, Cloud Run service or Azure Function) but metadata, metrics and query logs stay in Monte Carlo's cloud in every model |
| Connections | |
| Connectors | Broad and platform-shaped: Snowflake, Databricks across all three clouds, BigQuery, Redshift, Postgres, MySQL, Oracle and SQL Server; lakes through EMR, Glue, Hive, Presto and Spark; BI through Looker, Tableau, Power BI, Mode, Sisense and Sigma; Airflow, dbt, Prefect and Fivetran on the pipeline side; plus Alation, GitHub and the alerting channels |
| Cost | |
| Billing unit | Nothing published: montecarlo.ai/pricing redirects to a request form, so neither a price nor a unit can be recorded. The same answer Collibra and Atlan give in data-catalog, and the sharpest possible contrast with the free libraries sitting beside it here |
