Generators

Generate sample data on demand.

Produce random values and sample data without reaching for a spreadsheet. Each tool does one job well and runs right in your browser, with no signup and nothing uploaded.

All generators

Sample data on tap

Sometimes you just need a number that looks real. A height for a character, a set of values to plot in class, or dummy data to test a form. These tools produce those figures on demand, so you can grab what you need and get back to the actual work. There is nothing to learn and no account to create.

Private by design

Every tool here runs locally in your browser. When you set a range and generate, the work happens on your own device and nothing is sent to a server. That keeps the tools fast, since there is no round trip to wait on, and it means your inputs stay with you. Once a page has loaded, most keep working even if you go offline.

Frequently asked questions

Are these tools free?
Yes. Every tool here is completely free with no signup, no limits, and no watermarks. Use them as often as you like.
Do the results stay private?
Yes. These tools run entirely in your browser, so your inputs and results are never uploaded to a server. Once a page has loaded you can even use it offline.
Do I need to install anything?
No. The tools work in any modern web browser on desktop or mobile. There is nothing to download and no extension to add.
