There are so much redundant user agents. How to generate much more non-redundant user agent??

Hi @tenkuken, the fingerprint-suite tools are based on a random generator - therefore, there is no straightforward way how to generate non-redundant data. This, however, doesn't mean you cannot get a list of non-duplicate user-agents - you just have to deal with it in your own code. Here is an example of how you can do this:

const { HeaderGenerator } = require('header-generator');
const headerGenerator = new HeaderGenerator();

const userAgents = {};

for (let i = 0; i < 1e4; i++) {
    const userAgent = headerGenerator.getHeaders()['user-agent'];
    userAgents[userAgent] = true;
}

console.log(Object.keys(userAgents)); 

In this snippet, we generate 10000 header sets and deduplicate the user agents by using them as keys in a JavaScript object.

Please note that the looser constraints you set for the generator (by removing the 'locales', 'operatingSystems' or 'devices' options from the getFingerprint() call), the more distinct user-agent strings the generator will be able to generate.

---

A very important footnote:

If you really need only the user-agent strings (or some other HTTP headers) you'll be much better off with using HeaderGenerator instead of FingerprintGenerator. Here is a graph of run times for the script above using different tools to generate user-agent strings:

You see that the header-generator (in my snippet above) is the fastest option with an average run time of just under 2 seconds, and the fingerprint-generator option (from your snippet) is the slowest one with 8s. This is because the fingerprint-generator uses a much larger model for generating not only the user-agent string but also screen dimensions, different Web API values, etc.

Feel free to use the script I provided above :)

I'll close this issue as wontfix, but feel free to ask additional questions if you get any.
