Features

Everything you need.
Nothing you don't.

DataVow covers the full data contract lifecycle in one tool. No plugin sprawl. No vendor lock-in.

Define

YAML contracts based on ODCS v3.1

Readable. Versionable. Standard. Define schemas, quality rules, SLAs, and ownership in a single file. No Python required.

DataVow implements a superset of the Open Data Contract Standard (ODCS v3.1). Your contracts are interoperable, portable, and backed by an open standard — not locked to a vendor.

Validate

One command. Any data source.

📁

Files

Parquet, CSV, JSON — DuckDB reads them all natively. No import step, no staging table. Point at a file, get a verdict.

🗄️

Databases

PostgreSQL and MySQL via DuckDB ATTACH. Validate data where it lives. No extraction needed.

🔄

dbt integration

Read manifest.json and validate your models against contracts. Use as a post-hook — contracts break the build, not production.

🏗️

Airflow operator

DataVowValidateOperator drops into any DAG. Validate at ingestion, after transformation, before delivery.

How DataVow compares

Built for the gaps others leave.

DataVow isn't another observability platform. It's the missing enforcement layer.
