TDM readiness assessment
Twelve questions about how your team produces test data today, scored by category with prioritised next steps.
Tools
Free test data engineering tools
Practical calculators and planners for test data management. They run entirely in your browser, need no signup and never ask for data values.
Test-data storage and cost calculator
Compare full production copies with subsets, compression, shared certified datasets, retention and incremental refresh.
Subset-size calculator
Estimate how many rows and bytes an entity-based subset keeps, table by table, from row counts and fan-out.
Masking-policy starter
Pick columns from an example schema or type column names, choose strategies, and get a policy in the DataNivra format.
Synthetic-scenario planner
Plan normal, rare, boundary, historical and negative-test scenarios from the templates the industry packs ship.
CI/CD test-data readiness checklist
Check whether your pipelines get safe, reproducible, governed test data, and see what to fix first.
How these tools treat your input
The tools are static code running on this page. They make no network requests, keep no server-side record and ask only for counts, choices and names of tables or columns. Do not paste real data values into any field; none of the tools need them.
