About Mostly AI
Key Strengths
- Synthetic data platform for privacy-safe tabular datasets, now with an Apache-2.0 open-source Synthetic Data SDK
- SDK can train and generate locally on your own compute with no platform fee (CLIENT mode talks to the hosted app)
- Hosted free tier offers daily credits so you can try generation before buying
Limitations to Consider
- Hosted paid limits and credit packs are not fully published — often need to contact sales
- Synthetic data quality still needs domain validation; it is not a drop-in for every regulated dataset
- Best results assume you can run Python training jobs and understand tabular fidelity metrics
Best For
Data and ML teams that need synthetic tabular data and prefer an open SDK they can run locally.
Skip it if: You only need a hosted GUI with transparent published pricing and no local setup.
