Inspect Structure
Upload a JSON export of your SQL Server database structure (tables, types, primary keys, identity columns, and references).
Developer & DBA Tooling
Fill complex SQL Server databases in seconds.
Export your database schema, apply simple rules, and generate thousands of rows of realistic, dependency-safe seed data. Completely deterministic.
- Deterministic
- Repeatable seed generation
- FK-Aware
- Respects table hierarchies
- Local-First
- Zero database writes by default
Loading...Database Seed Problems
Why database seeding is usually broken
Developers need rich, relational test data, but syncing real customer data is a compliance hazard, and generic faker scripts crash when they break database foreign keys.
- Manual scripting is tedious and prone to syntax bugs.
- Compliance policies make production snapshots illegal.
- Orphaned relationships cause index and join failures.
How It Works
Three simple steps to safe, realistic mock data
Define Rules
Apply deterministic rules to columns (e.g. status lists, number bounds, emails, phone formulas) using our rules structure.
Export Output
Download a single, transaction-safe SQL script file or a folder of clean CSV files. Your database never receives direct writes.
Efficiency Metric
Calculate your development time saved
By automating mock database schema generation and eliminating manual data integrity fixes, you free up senior engineering hours for real feature work.
