Generatedata

What Generatedata is

Generatedata creates synthetic test data through a browser-based interface, with a self-hosted script option. It lists more than 30 data types, including names, emails, and countries, and lets users preview results while assembling a dataset. Related country, region, and city values can be generated together. Output choices include more than 10 formats, such as 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 size limits, and can save dataset configurations without a stated count or size limit; it also tracks the last 200 edits. The listed Registered account plan costs $25, paid once. The maker describes the script as an open-source project available free on GitHub, but setting it up requires developer experience. The hosted website adds account and dataset management. In a January 2026 update, the maker said version 5.x was being re-engineered as a monorepo and the website update would take longer than the script release.

Who it suits

Generatedata suits developers and testers who need synthetic datasets in varied formats or linked geographic fields. The self-hosted option is for people with the developer experience needed to set up the script.

Limits

The free plan limits generation to 500 rows at a time. Registered accounts remove that cap, subject to browser download size limits; the listed Registered account plan costs $25, paid once.

Verdict

Generatedata supports varied synthetic data types, linked geographic values, and many export formats. Consider the row cap, browser download limits, or setup requirements based on whether you use the hosted service or self-host the script.
