What RandomUser is
RandomUser is a free, open-source API that generates synthetic user data for application testing. Its output can include names, location, email, login details, birth and registration information, phone, photos, and nationality. Results are available as JSON, PrettyJSON, CSV, YAML, or XML. Requests can filter by gender or nationality, use a seed, paginate, and include or omit selected fields. Callers can configure password character sets and length; the default length is 8–64 characters. The API selects its latest version by default, and callers can request a specific version such as 1.4. The documentation demonstrates browser requests with AJAX and includes a jQuery example. RandomUser is available through the web and API. Its free plan is listed as free, with donations optional and up to 5,000 generated users per request. The maker also describes free Photoshop and Sketch extensions for bringing random users into design documents. The Photoshop extension does not work with CC 2017 and has no update ETA; the Sketch extension is still under development.
