Synthetic data that understands your schema
Generate production-quality test data in seconds. SchemaSage respects every constraint, relationship, and edge case — so your team ships faster without ever touching real customer data.
Everything you need to generate realistic data
From schema parsing to statistical distributions, SchemaSage handles the hard parts so you can focus on building great software.
Schema-Aware Generation
Define your tables, columns, and data types once. SchemaSage generates data that fits your schema perfectly, every time — no manual tweaking required.
Constraint & Relationship Fidelity
Foreign keys, unique constraints, check rules, and complex joins are honored automatically. Your synthetic datasets behave exactly like production.
Privacy by Design
Generate realistic data without touching real customer records. Meet GDPR, HIPAA, and SOC 2 requirements while giving your team the datasets they need.
Instant Volume Scaling
Need 100 rows for a unit test or 10 million for a load test? Adjust the volume slider and generate in seconds, not hours.
Flexible Export Formats
Export as SQL inserts, CSV, JSON, Parquet, or stream directly to your database. Integrate with CI/CD pipelines for automated test data provisioning.
Statistical Distribution Control
Configure data distributions, null rates, and edge cases to match real-world patterns. Catch bugs that only surface with realistic data shapes.

Engineering Manager, FinTech Startup
We used to copy production databases and scrub PII. Now we generate safe, realistic datasets that actually respect our foreign key relationships.
Marcus Chen
Lead Data Engineer, Healthcare Platform
The schema-awareness is what sold us. Every other tool we tried produced data that broke our constraints within the first hundred rows.
