Mock User Generator

Runs in browser Mocking

JSON fixtures shaped for UI development — consistent ids, ISO timestamps, nested profile and settings objects. Synthetic test data only.

TEST DATA ONLY — all generated names, contacts, identifiers and numbers are synthetic and do not belong to real people or accounts.

Mock User Generator example

One nested user

Input:

Count: 1, ids: integer, nested: yes

Output:

[{ "id": 1, "username": "andrew_sullivan72", "email": "andrew.sullivan@example.io", "firstName": "Andrew", "lastName": "Sullivan", "role": "admin", "status": "active", "emailVerified": true, "profile": { "jobTitle": "QA Lead", … }, "preferences": { "theme": "dark", … }, "createdAt": "2023-04-02T09:14:31Z" }]

Frequently asked questions about Mock User Generator

What does a mock user contain?

id, username, email, first/last/display name, avatar URL, role, status, verification flag, phone, locale, timezone, timestamps and optionally a profile (bio, company, job, location, birth date), preferences (theme, notifications, 2FA) and stats.

Are these real people?

No. Names are drawn from common name lists and combined randomly; emails use reserved example.com domains and phone numbers use the fictional 555 range.

How do I get the same users every time?

Set a seed. Storybook stories, snapshot tests and demos stay stable while Regenerate without a seed gives fresh data.

Can I get a single object or an envelope?

Choose Array, a { data, meta } envelope or a single object from the Shape option, and integer or UUID ids.
