The gold standard in data validation
Whether you’re migrating, testing, or monitoring, Data Diff ensures your data is accurate, consistent, and ready for every cutover, release, and production run.
Validate your data, end to end
Migrate with confidence
When moving from a legacy system to a new platform, Data Diff validates every value to ensure your target matches your source. This eliminates the guesswork in cutovers. The result: a migration that’s cheaper, faster, and ready for production on day one.
Test before you ship
Validate every transformation in CI/CD to see how code changes affect your data and BI assets. Catch discrepancies early, confirm transformations work as intended, and prevent bad data from ever reaching your users. With automated checks in staging, you release faster and with full confidence in your data.
Monitor production data
Continuously validate your most critical tables to catch unexpected changes the moment they happen. With automated monitoring in production, Data Diff protects downstream reports, dashboards, and decisions.
Validate with precision, ship with confidence
Compare any source, any scale
Compare data between any two systems, environments, or points in time. From a single table to billions of rows, Data Diff handles it with accuracy and speed.
Catch what other tests miss
Data Diff is the gold standard for validating datasets after a code change. Predefined tests and aggregate checks leave critical gaps like missed null values, shifted joins, or silent schema changes. By comparing every value, you uncover discrepancies no other method can.
Let AI do the heavy lifting
AI-assisted code review goes beyond the query and shows you the actual impact on your data. Every pull request highlights the changes that matter so reviewers can focus on outcomes, not syntax. The result: faster reviews, fewer errors, and more time spent shipping.
Automate your checks
Run Data Diff on demand or integrate it into CI/CD pipelines and monitoring schedules to eliminate repetitive QA work and keep projects moving at full speed.
How our customers are ensuring data quality with speed and confidence
"Datafold helps you find the hidden changes you didn't know you made to your data, helping you if they're unintended or understanding what's causing them."
