What SynthForge IO is

SynthForge IO generates synthetic test data from database schemas for development, QA, and load testing. Users can describe a model in plain English, make it in a visual editor, import SQL DDL, or start from a template. Generation orders tables by dependency and keeps child foreign keys connected to existing parent rows. It provides 152 field types across 19 categories, with value constraints, statistical distributions, and conditional overrides. Exports include CSV, SQL for seven dialects, JSON, JSONL, and Parquet; MongoDB-ready data is available in JSON or JSONL. Personal API keys use Bearer-token authentication, and datasets can be generated from curl, Python, or the CLI. Hosted MCP is in open beta and supports Claude, Cursor, and Streamable HTTP MCP clients. The free plan covers the first 20,000 rows of each dataset, with generation capped at 1,000,000 rows per table and downloads capped at 1 GB. Stored generated datasets are encrypted and automatically deleted after roughly 24 hours. A $5 credit purchase is available.
