Spec score 7.8 #13 of 29 in Synthetic Data Generation Software

What it is

SynthForge IO generates synthetic data from database schemas for development, quality assurance, and load testing. You can describe a model in plain English, draw it in a visual editor, import SQL DDL, or begin with a template. Generation follows table dependencies and keeps child foreign keys connected to existing parent rows. The service provides 152 field types in 19 categories, including constraints, statistical distributions, and conditional overrides. Outputs include CSV, JSON, JSONL, Parquet, and SQL for PostgreSQL, MySQL, SQL Server, SQLite, MariaDB, DuckDB, and CockroachDB. MongoDB-ready data is available as JSON or JSONL. Personal API keys use Bearer authentication and support curl, Python, and CLI jobs. Hosted MCP is in open beta for Claude, Cursor, and Streamable HTTP clients. The free plan includes the first 20,000 rows of each dataset; generation is capped at 1,000,000 rows per table and downloads at 1 GB. Paid credits start at $5, paid once.
