FAQ
Is voiddo fake an alternative to mockaroo.com?
Yes. voiddo fake (tools.voiddo.com/fake/) is a free browser-only fake test data generator. Choose field types, set row count, and generate JSON or CSV instantly in your browser — no server call, no account, no row limits for browser generation.
How is voiddo fake different from mockaroo.com?
mockaroo.com has 180+ field types, saved schemas, API access, and team sharing, but limits free-tier downloads to 1,000 rows and requires an account for schema saving and API. voiddo fake runs entirely in your browser, has no row limits for browser generation, requires no account, and is zero-config for quick test data. For large datasets, custom formulas, or team schema sharing, mockaroo is the better choice.
Does voiddo fake send my data to a server?
No. All generation runs in the browser using JavaScript random data generation. No network request is made during generation. Your schema configuration and output never leaves your browser tab — important if even fake data patterns (field names, formats) should not be transmitted to third-party servers.
What field types does voiddo fake support?
voiddo fake supports: full name, first name, last name, email, UUID v4, phone number, street address, city, country, postal code, company name, job title, URL, integer (min/max), float (precision), boolean, date (range), lorem sentence, and lorem paragraph. For 180+ specialised types including IBAN, MAC address, and medical record number, use mockaroo.com.
Can I export fake data as CSV?
Yes. voiddo fake generates both JSON array output and CSV output with headers. Both formats are copy-to-clipboard or downloadable as a file. This covers the most common use cases: seeding test databases, populating fixtures, demo API responses, and UI stress testing.
Is voiddo fake free?
Yes — completely free with no account, no ads, no row limits for browser generation, and no paywalls. It is part of the 50+ free developer tools at tools.voiddo.com.
