About RandTools.

RandTools has 20 task pages organized into six workspaces: people, addresses and places, companies, colors, test data, and random choices. Generate a single value, create a fictional profile, or export a sample dataset. Each mode opens directly, and the tools are free to use without an account.

What happens in your browser

Randomization and sample-data generation happen on your device. Loading the site still uses the network for application files, datasets, fonts and analytics. Copying or downloading a result is an action you choose; the generators do not send those results to a processing server.

Where the outputs come from

Different tools use different sources: bundled lists for suggestions, Faker for some fictional names and sample fields, and algorithms for values such as numbers, colors and UUIDs. A list-based tool selects from its included entries, rather than from every possible item in the world.

Ordinary selection tools use browser pseudorandomness. UUID tools use browser cryptography APIs. Filters and repeat-prevention rules can affect which result is shown. Read the practical examples and randomness guide to choose a tool and understand those limits.

How to use descriptive data

Information cards help explain a suggestion, but they are not a current reference database. Population and other location facts may be approximate or become outdated. Check an appropriate source before relying on a factual claim. Generated identities are fictional test material and can resemble real details by coincidence.

Maintenance and corrections

The maintainer updates tools and explanations as issues are identified. Page revision dates indicate a content update, not a claim that every record or device was reviewed that day. If a dataset entry, control or explanation is wrong, include the page URL and a reproducible example when reporting it.

Funding and privacy

Display advertising is not currently enabled. If it is introduced, advertisements will be distinguished from tool controls and the privacy information and applicable consent choices will be updated first. The site currently uses Google Analytics, Umami analytics on our own server and Cloudflare hosting; see the privacy policy for details.
