Generatedata

What Generatedata is

Generatedata creates synthetic test data through a browser interface, with a self-hosted script for users who want to run it themselves. The generator lists more than 30 data types, including names, emails, and countries, and shows previews while you build a dataset. Related country, region, and city fields can be generated together. Output formats include JSON, CSV, XML, SQL, HTML, JavaScript, TypeScript, PHP, Perl, C#, Ruby, and Python. Without registration, generation is limited to 500 rows at a time. A registered account removes that cap subject to browser download limits, saves dataset configurations without a stated size or count limit, and tracks the last 200 edits. The Registered account plan costs $25, paid once. The maker describes the script as open source and free on GitHub, although setup requires developer experience. The hosted site adds account and dataset management. In a January 2026 update, the maker said version 5.x was being re-engineered as a monorepo.
