Getting started with Data Maestro

A native Mac app for generating realistic fake data, finding and masking real PII, and seeding databases — with a headless CLI backed by the same engine for CI. This is a tour of the app itself.

Your trial

The app opens straight into a 30-day trial with every feature unlocked — no license key needed to start. A countdown in Settings → Licensing tracks the days remaining.

Once the trial lapses, the app shows a full-screen license prompt instead of the workspace — enter a key there (or from Settings) to keep going. See Licensing & Settings for what each tier unlocks and how to activate a key.

The workspace

The left sidebar is split into two groups. Click any panel below to jump to its help page.

Workspace

Data Generator

Design a schema, preview rows, export to a file or a database.

PII Anonymizer

Scan files and databases for PII, then mask or replace it.

Schema Importer

Discover a schema from an existing file or database table.

Fake API Generator

Serve your schema from a live local REST endpoint.

Database Connectors

Save connections, browse data with the Data Viewer.

Collections

Templates & Custom Datasets

Save schemas and reusable value lists for reuse anywhere.

Job Scheduler

Run generation and anonymization jobs on a recurring schedule.

Audit Trails

A read-only log of everything the app has done.

Licensing & Settings

Appearance, updates, encryption-at-rest, and your license — ⌘,

Build your first dataset

  • Open Data Generator and add fields under Schema Config — give each a name and a type.
  • Switch to Data Preview to see 10 live rows update as you edit the schema.
  • Switch to Export to File to pick a format and row count, or Export to Database to push straight into a saved connection.
  • Save the schema from the right sidebar so it shows up later in Templates.
