Write one record as a template with placeholders like {{name}}, {{email}} or {{int(1, 500)}}, choose how many you need, and get an array of realistic fake records — for mocks, fixtures, load tests and demos.
Runs entirely in your browser — nothing you enter here is sent to a server.
Mock APIs, UI prototypes, database fixtures and load tests all need data, and "test1", "test2" hides problems that real data shows at once: long names that break a layout, accented characters that break an encoding, numbers in a range the code did not expect. A template gives you control over the shape of every record and realistic values in every field.
A field that is only a placeholder becomes the right JSON type: "{{int(1, 9)}}" turns into the number 7, "{{bool}}" into true. Placeholders inside longer text stay strings.
Within one record, the name, email and username belong to the same invented person, and the city matches the country.
The seed fixes the random sequence. Keep the seed and template in your repository and anyone can regenerate the exact same fixtures.
Emails use reserved example domains and phone numbers the fictional 555 range, so generated data never reaches a real person.
{{int(-5, 100000)}} or a long {{lorem(60)}} on purpose to see how the code handles values at the limits.Put the placeholder alone in the quotes: "count": "{{int(1, 100)}}" becomes "count": 42. If there is other text around it, such as "Order #{{int(1, 100)}}", the result stays a string.
Yes. The same template, record count and seed always produce exactly the same output. Change the seed for a different set.
Up to 10,000 per run, in your browser. For larger sets, generate with the same template several times using different seeds and combine the files.
No. Names, companies and addresses are combined at random from short lists, emails use reserved example domains and phone numbers the 555 range, so none of it belongs to a real person.
