Monte Carlo: Enterprise leader. ML-based anomaly detection. Integrates with major platforms. Expensive but thorough.
Soda: Open core model. SQL-based checks. Good middle ground between DIY and enterprise.
Elementary: dbt-native. Runs inside your dbt project. Open source core, with optional paid cloud features. Great for dbt-centric stacks.
DIY approach: Build with Great Expectations + Airflow + PagerDuty. More work but full control.
When to choose:
- Early stage: Elementary or DIY
- Growth stage: Soda
- Enterprise with budget: Monte Carlo
