Realistic JSON test data in one click
Stubbing out an API, seeding a UI, or writing tests? This mock JSON generator produces formatted, realistic records for users, products and blog posts — ready to paste into your code.
Pick a template, choose how many records you want, and decide whether a single record should be wrapped in an array. UUIDs use the browser’s secure crypto API, and the whole thing runs locally so your test data never leaves your machine.
