About DataGeneratorHub
DataGeneratorHub is a collection of free browser-based generators and utilities for creating sample values, preparing test fixtures, and making everyday random selections. The tools are intended to help with development, demos, mockups, QA, and other low-risk testing tasks.
What you can do here
Browse tools for numbers, identity-style examples, locations, dates, text, technical fixtures, and more. Each tool page describes its options and intended use. The featuredTest Data Generatorcreates synthetic record batches that can be copied or exported as JSON, CSV, or PostgreSQL SQL.
How the tools work
Each tool applies its own options and rules. Depending on the tool, it may select from built-in example lists, assemble a value from a format or range, or transform text you enter. Results are produced when you use a tool; they are not checked against live identity, carrier, postal, or account databases unless that specific page says otherwise.
What generated results mean
A value that matches a familiar format is not necessarily real, assigned, reachable, deliverable, unique, or valid for an external service. Treat generated identities, contact details, addresses, and credentials as examples only. Do not use them to contact people, access accounts, or make production decisions. Follow the limits and safety notes shown on each tool page.
Privacy and feedback
