MOSTLY AI vs REaLTabFormer

MOSTLY AI is a data intelligence platform for accessing production data, generating synthetic, mock and simulated data, and analyzing data. Its assistant lets users request Python code in natural language and run it for analysis. The open-source Synthetic Data SDK supports local generation and uses the Apache v2 license. The platform handles numerical, categorical, date-time, text and geolocation data; it can synthesize relational tables while preserving their relationships. Other controls include Data Insights Reports, data rebalancing, missing-value imputation and generation temperature settings. Listed database connectors include MySQL, PostgreSQL, MariaDB, Oracle, Microsoft SQL Server, Snowflake, Databricks, BigQuery and Apache Hive; cloud bucket connectors include Azure, GCP and AWS. An API and Python client support integration into applications and workflows. Deployment options include Kubernetes, OpenShift and Minikube, as well as on-premises, private-cloud and air-gapped installations. The maker says the platform is SOC 2 and ISO 27001 certified. A single-node Kubernetes deployment requires at least 24 CPU cores, 48 GB RAM and 256 GB storage. The free plan is free, with no further limits stated. It is available via API, Linux, self-hosting and web.

REaLTabFormer is a free, MIT-licensed framework for generating synthetic tabular and relational data. Its relational model uses a sequence-to-sequence approach, while its model for independent tabular observations uses GPT-2. Examples use pandas DataFrames as input; relational generation requires matching join-key columns in the parent and child tables. The documented workflow fits a model, saves it locally and samples synthetic data. For non-relational training, it stops when the synthetic distribution is close to the real data distribution. Observation validators can filter invalid samples, including through a GeoValidator example. The paper describes target masking to prevent data copying and the Qδ statistic with statistical bootstrapping to detect overfitting. Installation uses `pip install realtabformer`; the current PyPI package requires Python 3.8 or newer. PyPI classifies it as operating-system independent, and Linux, macOS, Windows and self-hosted platforms are listed. The project describes use in projects or research and asks users to cite its research paper when using it. For vulnerability reports, its policy directs users to email rather than post publicly and says a response should arrive within 48 hours.
