Open Source Synthetic Data with MOSTLY AI

Contents
Why synthetic data?
Enterprises hold vast amounts of valuable customer data, but privacy and compliance barriers often keep it locked away. Synthetic data solves this by generating realistic, privacy-safe datasets that retain the utility of the original while eliminating sensitive information.
With synthetic data, organizations can:
- Train AI safely on representative data without the potential for exposing PII.
- Accelerate analytics and insights without compliance delays.
- Share realistic demo environments loaded with data externally while protecting confidentiality.
- Build realistic ETL and migration pipelines using privacy-safe production-like datasets.
- Test and QA software with lifelike data.
- Ensure fairness and explainability by stress-testing AI with tailored scenarios.
Synthetic data unlocks access to sensitive datasets, enabling faster innovation, safer collaboration, and trusted AI adoption at scale.
What is MOSTLY AI?
MOSTLY AI is on a mission to unlock Data for Everyone while preserving data privacy and utility. By treating synthetic data as a first-class citizen that coexists with real data, MOSTLY AI helps teams build robust data foundations and accelerate the adoption of next-generation AI systems. Through high-fidelity, privacy-safe synthetic data, organizations can strengthen trust, improve data access, and unlock new opportunities for growth.
As a part of our mission, we've released the Synthetic Data SDK.
The Synthetic Data SDK
The MOSTLY AI platform is powered by the Synthetic Data SDK, an open-source toolkit for generating high-fidelity, privacy-safe synthetic data. The SDK gives developers direct control to train generators, create synthetic datasets, and connect to data sources programmatically.
All methods and endpoints are fully documented with usage examples and recommended configurations, making it easy to get started and customize for specific needs. Since the entire codebase is publicly available, teams can inspect, extend, and trust the SDK as a transparent foundation for their synthetic data workflows.
