Is there an offline alternative to random.org?

Short answer

random.org is a genuinely free service that generates true random numbers from atmospheric noise on its own servers and delivers them over the internet. If you just need to pick a number, a name or a winner privately, a browser-based generator does it locally on your device, with no network request and nothing about your draw leaving your machine.

The key difference: where the randomness comes from

random.org is a well-respected service whose defining feature is true randomness derived from atmospheric noise, generated on its servers and served to you over the internet. A browser-based generator produces its results locally on your device instead: no request is made to any service, which means it keeps working offline and the details of your draw, the range, the list of names, the winner, are never sent anywhere.

When the browser option is better

For everyday uses, picking a giveaway winner, drawing names in a classroom, generating numbers for a game, a local generator is more than random enough and is instant, private and offline-friendly. Where random.org still shines is when you specifically want hardware-derived randomness or an independent third party to run a drawing; for a quick fair pick on your own machine, the local tool covers it.

Frequently asked questions

Does it work offline?

Yes. Once the page has loaded, numbers and picks are generated on your device with no network request.

Is a browser random number good enough for a giveaway?

Yes. For picks, draws and games, locally generated randomness is fair and unpredictable in practice. random.org’s atmospheric noise matters mainly for specialized needs.

Can I pick names, not just numbers?

Yes. Paste a list of names and the picker selects a winner at random, with an animated name picker for live draws.
