Join a growing community of developers and data engineers building with SynthForge.
How It Works
From idea to dataset in three simple steps
Describe
Tell us what you need in plain English, or start with a built-in template. Our AI understands your requirements.
Design
Review the generated schema in our visual editor. Add tables, define relationships, and customize field types.
Generate
Generate up to 1 million rows of realistic, relationship-aware data. Export in CSV, JSON, SQL, and more.
Visual Schema Editor
Whether you start with an AI-generated schema, a built-in template, or a blank canvas, our visual editor gives you full control to design and refine your database structure.
- Drag-and-drop table creation
- Visual relationship connections (1:1, 1:M, M:M)
- 100+ field types with smart defaults
- Real-time sample data preview
- Inline table and column editing
- Minimap and zoom controls
Why SynthForge?
Powerful features for generating realistic synthetic data
Natural Language Schemas
Describe your data in plain English and SynthForge infers entities, relationships, and constraints to generate relational datasets that match your intent.
Custom Schema Design
Start with a prebuilt template, build from scratch, or refine AI-generated structures. Define fields, types, and relationships to fit your exact needs.
Realistic Data at Scale
Create synthetic data at scale with consistent relationships for testing, demos, or any large-scale dataset need.
Built For You
Whether you're testing, demoing, or training models
Developers
Populate development databases with realistic test data. Build and test features without waiting for production data or risking privacy issues.
QA Engineers
Generate edge cases and large volumes of test data. Validate application behavior with diverse, realistic datasets that cover all scenarios.
Data Scientists
Train and validate models with synthetic datasets. Create balanced, unbiased data without privacy concerns or data access delays.
Export Anywhere
Download your data in the format you need
CSV
JSON
SQL
Parquet
SQLite
SQL exports support PostgreSQL, MySQL, SQL Server, MariaDB, DuckDB, and CockroachDB
Start with Built-in Templates
Don't start from scratch. Choose from pre-built scenarios for common use cases and customize them to fit your needs.
100% Synthetic. Zero Privacy Risk.
All data generated by SynthForge is completely synthetic. No real personal information is ever used. Use it freely for development, testing, and demos without privacy concerns or compliance issues.

Who We Are
We're developers, data engineers, and AI enthusiasts who started building SynthForge in early 2025. We saw a need for a high-performance, relationship-aware synthetic data generator that anyone can use, without the complexity of existing tools or the risk of using real data.
We're excited to finally bring SynthForge to the community and can't wait to see what you build with it!
Have questions or feedback? We'd love to hear from you.
