SynthForge IO
SynthForge IO generates synthetic data from database schemas for development, QA, and load testing.
What SynthForge IO is
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.

Who it suits
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.
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.
