About Randomly

Randomly is a small site of generators and validators I keep for work that should stay in the browser. UUIDs, IBANs, hashes, names, test cards with a Luhn check, VIN check digits. Over a hundred tools now, plus a few datasets we sample from public sources.

I built it because I was tired of spinning up a REPL every time I needed a valid-looking IBAN or a UUID v7. Most of the pages do the same job: pick a format, generate locally, copy it. Nothing you type is sent to our servers to create that value. The algorithms live in the page.

What we run on the server

Some catalog tools (cities, names, books) pull a small sample from datasets we publish in Cloudflare R2. Those samples are public reference data, not your input. We also use Google Analytics on the public site so we can see which tools people open. That is tracking. It is described on the privacy page.

What this is not

It is not a bank, a credit bureau, or a government form. Generated numbers are for software tests and fixtures. Do not use a generated SSN, card number, or routing number as if it were issued to a real person. Validators check format and checksums. They do not prove an account exists.

If something is wrong, use the contact page. If you want the tools, start at all tools or the blog.
