sdv
Generate synthetic data for single table, multi table and sequential data
Decision gist · record as of 2026-08-14
Yes, with conditions. SDV is actively maintained, has no known vulnerabilities, and low install friction. It's a mature tool (Production/Stable status) for a real need—synthetic data generation with privacy controls. However, the BUSL-1.1 license treatment is unclear; verify the license terms match your use case (commercial, internal, or research) before committing to production deployment. If licensing is acceptable, it's a solid choice for tabular synthetic data work.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with a pure Python wheel.
- Active maintenance with a release 7 days ago and consistent development activity.
- Supports Python 3.9 through 3.14.

What it is and what it does
SDV is a Python library for generating synthetic tabular data that mimics real datasets while protecting sensitive information. It offers multiple machine learning models—from classical statistical methods like GaussianCopula to deep learning approaches like CTGAN—to learn and replicate patterns in your data. The library handles single tables, multiple connected tables, and sequential data, with built-in support for preprocessing, anonymization, and business rule constraints.
The typical workflow involves loading or preparing your real data with metadata, selecting a synthesizer model, fitting it to learn patterns, then sampling synthetic rows. SDV also provides evaluation tools to measure how well the synthetic data matches the real data's statistical properties and to visualize differences. It depends on a substantial stack including pandas, numpy, copulas, ctgan, deepecho, rdt, and sdmetrics for its core functionality.
Use it for
- Generate test datasets for development and QA without exposing real customer or sensitive data
- Create shareable datasets for research or collaboration while maintaining privacy compliance
- Augment small datasets with synthetic rows to improve machine learning model training
- Evaluate data quality and statistical fidelity between real and synthetic versions
- Prototype data pipelines and analytics on realistic synthetic data before deploying to production
