Summary

MOSTLY AI is a data intelligence platform for accessing production data and generating synthetic, mock and simulated data, with tools for data analysis. Its assistant turns natural-language requests into Python code that users can run for analysis. The open-source Synthetic Data SDK, licensed under Apache v2, supports local generation. Data types include numerical, categorical, date-time, text and geolocation data; multi-table synthesis preserves relationships between tables. The platform also offers data insights reports, rebalancing, missing-value imputation and generation temperature controls. Listed connectors cover databases including MySQL, PostgreSQL, MariaDB, Oracle, Microsoft SQL Server, Snowflake, Databricks, BigQuery and Apache Hive, plus Azure, GCP and AWS cloud buckets. An API and Python client are available for integrating generation into applications and workflows. Deployment options include Kubernetes, OpenShift and Minikube, as well as on-premises, private cloud and air-gapped environments. The free plan is 0.00 USD per free, with no further limits stated.

Who it is for

MOSTLY AI suits data teams that need synthetic datasets, including relational tables, or want to integrate generation through an API or Python client. Its deployment options also suit organizations seeking on-premises, private-cloud or air-gapped installation.

What is good

Synthesizes related tables while preserving their relationships.
SDK supports local synthetic data generation.
Offers data insights, rebalancing and missing-value imputation.
API and Python client support workflow integration.
On-premises and air-gapped deployment options are available.

What to know first

SDK local-mode GPU support is Linux-only.
Single-node Kubernetes needs at least 24 CPU cores.
That deployment also requires 48 GB RAM and 256 GB storage.

Verdict

MOSTLY AI offers several ways to generate and integrate synthetic data, alongside analysis tools and support for multiple data types. Check the substantial minimum resources for single-node Kubernetes and the Linux-only GPU support in local SDK mode.
