What RandomUser is

RandomUser is a free, open-source API that generates synthetic user data for application testing. Requests can return names, location, email, login details, birth and registration information, phone, photos, and nationality in JSON, PrettyJSON, CSV, YAML, or XML. You can filter by gender or nationality, set a seed, paginate results, and choose which fields to include or exclude. Password options allow selection of character sets and configurable length; the default range is 8–64 characters. The API uses its latest version unless a caller specifies one, such as 1.4. Documentation includes browser calls using AJAX and a jQuery example. RandomUser is available on the web and through its API. Its free plan costs nothing, with optional donations, and allows up to 5,000 generated users per request. The maker also describes free Photoshop and Sketch extensions for design documents; the Photoshop extension does not work with CC 2017 and has no update ETA, while the Sketch extension remains in development.
