Categories

Ten scalable categories built for long-tail SEO and 500+ future tools.

Random Data Hub organizes generators into categories so you can find the right test data for your stack. Identity tools cover names, addresses, phones, emails, companies, cities, towns, countries, and complete random profiles with JSON download. Developer tools include UUID batches, JWT samples, SQL INSERT scripts, API mock JSON, and the custom schema mock data builder.

Design and placeholder categories help wireframes with QR codes, gradients, color palettes, avatar URLs, and sized placeholder images. Security-focused tools provide PCI test card numbers and fake IBAN strings for form validation only—not real payment or banking rails. Open any category to see tool counts, short descriptions, and links to each generator page with FAQs and usage guides.
