About Data Forge

Data Forge uses Qwen3 AI models running entirely in your browser via WebLLM. Choose from three model sizes based on your device capabilities. Models are downloaded once and cached locally for future use.

Define tables with columns and types, set up foreign key relationships, and generate contextually realistic data that respects your constraints. Export to SQL, JSON, or CSV for use in your development and testing workflows.
