SynthCity review
A broad, research-oriented toolkit for self-hosted synthetic-data workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SynthCity is an open-source Python library for generating and evaluating synthetic data. It is aimed at researchers, developers, and machine-learning teams building or assessing synthetic-data workflows. The library covers tabular datasets, time series, survival-analysis data, and images, giving teams one framework for working across several data modalities. It can be installed locally with pip and is designed for self-hosted deployment.
Its standout strength is the combination of generation and evaluation. A plugin-based architecture supports generative modeling, privacy, fairness, and domain adaptation, while the library includes metrics for data quality, utility, and privacy. Privacy-focused generators include differential-privacy methods, and fairness-oriented generation is also part of the feature set. Synthetic-model serialization and loading add a practical way to preserve and reuse trained synthetic-data models within a development workflow. Researchers comparing approaches across modalities will find the breadth particularly useful.
SynthCity is a strong fit for teams that want an open-source, self-hosted component with API access and room to evaluate trade-offs among quality, utility, privacy, and fairness. Its library format favors users who can work within a Python and machine-learning development environment. Teams looking for a managed hosted service, a ready-made user interface, or a narrowly focused generator should choose a product built around those priorities instead. SynthCity is most compelling when experimentation, extensibility, and transparent evaluation matter more than turnkey operations.
SynthCity pros and cons
- Where it wins
- Supports tabular, time-series, survival, and image data generation
- Includes privacy, fairness, quality, utility, and privacy metrics
- Plugin architecture supports generator extensions and model serialization
- Where it doesn't
- Self-hosted deployment places infrastructure responsibility on the user
- Python-library format may require development and machine-learning expertise
- A broad plugin scope may be more than teams need for one modality
