Summary

SynthForge IO generates synthetic data from database schemas for development, QA, and load testing. You can define a model in plain English, use a visual editor, import SQL DDL, or begin with a template. During generation, it orders related tables by dependency and links child foreign keys to existing parent rows. Its generators cover 152 field types across 19 categories, with value constraints, statistical distributions, and conditional overrides. Export options include CSV, SQL for PostgreSQL, MySQL, SQL Server, SQLite, MariaDB, DuckDB, and CockroachDB, plus JSON, JSONL, and Parquet. MongoDB-ready data is available in JSON or JSONL. The web app and API are available, and personal API keys use Bearer-token authentication for jobs from curl, Python, or the CLI. Hosted MCP is in open beta for Claude, Cursor, and Streamable HTTP clients. The free plan includes the first 20,000 rows per dataset; limits include 1,000,000 rows per table and 1 GB per download. Paid credits start at $5.

Who it is for

It suits application developers, QA engineers, and data engineers who need realistic test datasets, including at production-scale volumes. Its range of schema inputs, exports, and API access may fit teams with different data workflows.

What is good

  • Build schemas in plain English, visually, from SQL, or templates.
  • Preserves parent-child foreign-key relationships during generation.
  • Offers 152 field types across 19 categories.
  • Exports CSV, SQL, JSON, JSONL, and Parquet.
  • Free plan covers the first 20,000 rows per dataset.

What to know first

  • No free trial is listed.
  • Downloads are limited to 1 GB.
  • Stored datasets are kept about 24 hours.
  • AI features may send descriptions and schemas to third parties.

Verdict

SynthForge IO combines multiple schema-design paths with relationally aware generation and several export formats. Note that it does not de-identify production data and lacks SOC 2 and HIPAA attestations.
