Why top-user-agents?

When performing HTTP requests that need to look like real browser traffic (web scraping, testing, automation), you need accurate and current user-agent strings.

Most user-agent lists on the Internet are outdated or unmaintained. This list is different:

• Collected from real traffic at microlink.io (+300M requests/month)
• Automatically updated via CI/CD pipeline
• Covers Chrome, Firefox, Safari, Edge, and more

Install

npm install top-user-agents

Usage

Get a random user-agent

const uniqueRandomArray = require('unique-random-array')
const userAgents = require('top-user-agents')

const randomUserAgent = uniqueRandomArray(userAgents)

console.log(randomUserAgent())
// => 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36'

Filter by device type

// Desktop browsers only
const desktopAgents = require('top-user-agents/desktop')

// Mobile browsers only
const mobileAgents = require('top-user-agents/mobile')

Use with fetch/HTTP requests

const userAgents = require('top-user-agents')

const response = await fetch('https://example.com', {
  headers: {
    'User-Agent': userAgents[0]
  }
})

About Privacy

The information exposed to the user-agent only relies on coarse details.

In practice, anyone can put whatever they want in the user-agent string, and send it to the web server.

Because that, The user-agent cannot be sufficient condition to identify or reproduce the original request.
