Internal tools and admin panels
Generate relational tables for lists, filters, related records, and edit flows so your frontend stops depending on brittle fixtures.
Free Tool
Try frontend product flows with realistic data before backend is ready
Describe the tables you need for an internal tool, customer dashboard, or SaaS workflow. Generate seeded relational data, inspect runtime API routes, and claim the workspace in Synthbrew when you want to keep building.
Free AI data generator
No signup requiredDescribe what data you need. We will generate schema, rows, runtime API routes, and a temporary API key. You can edit twice before claiming the workspace.
Try one:
Start here when you want proof, not a full setup. The guest workspace lets you validate the schema, data shape, and runtime routes first. Claim it in Synthbrew when you want a saved workspace, stable API keys, and room to keep iterating.
Customer dashboards and BI prototypes
Pressure-test chart data, drilldowns, and joins with seeded datasets that feel closer to production than flat CSV exports or random rows.
Claim the workspace when it is worth keeping
Once the generated schema and runtime routes look right, sign up or log in to save the workspace in Synthbrew and keep building from the same starting point.
Frequently asked questions
Is this AI data generator really free?

What do I get after generation?
You get table previews, runtime API route examples, and an API key for generated source access.
