Top User Agent List for Scraping in 2025 (Desktop & Mobile)

When you start scraping the web, you’ll notice that scripts are sometimes blocked seemingly without reason. Somehow, the website knows you’re not using a real browser, and sensing your intentions, it blocks your access.

There’s an easy way to tackle this — by changing your user agent. Keep reading to find out what a user agent is, which are the most common user agents, and how you can adjust your code to mimic the user agent of a browser.

Latest User Agents for 2025

If you need to pick a user agent string for your scraping script, the best bet is to just take the most commonly used one. It will blend with the other traffic sent to the website and not stand out.

Currently, the most common user agent is the following:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/138.0.0.0 Safari/537.36

It's the user agent of the latest Chrome browser running on Windows (starting from Windows 11, browsers don't discern between Windows versions in the browser).

While it might seem odd that there are mentions of other browsers in this user agent as well, there is a solid reason behind that .

Below is a user agent list for 2025, grouped by browser and OS. You can use this list to help rotate user agents for lower chances of detection:

Running the most popular user agents might seem counterintuitive, but it works best against various detection methods. You want your scraper or bot to look like a regular user, so the most popular user agents will blend in the best.

Keep in mind that the latest browser changes, so it's a good idea to research commonly used user agents and update your headers time by time.

Alternatively, you can just get the user agent string of your browser by googling the keyphrase “What's my user agent?”. Google should display your user agent string, which you can then set as the user agent for your script. Given that it's copied from a real browser, it should look natural enough to bypass most scraping restrictions.

What Is a User Agent, and Why Is It Important for Web Scraping?

When you send a request to a server through a browser or an HTTP client like the Requests library in Python, the request includes HTTP headers, which contain all kinds of information about this request.

Among other things, they also include a user agent header — a name that lets the server identify what kind of application the request comes from.

To see how it looks, you can use the following code. It uses the Requests library to send a request from your device. Then, it prints out the HTTP headers of that request in the console.

"https://iproyal.com/"
printresponserequestheaders

It should print out something like this:

{'User-Agent': 'python-requests/2.31.0', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive', 'Content-Length': '11', 'Content-Type': 'application/x-www-form-urlencoded'}

The relevant header in this case is the first one. As you see, the Requests library tells the server that you're using it.

HTTP headers can also reveal you're using a proxy. For a quick (and code-free) check, visit our proxy headers checker .

The user agent of web browsers looks slightly different from the user agent of standalone applications. Inside, it lists the version of the web browser, the operating system, and some other tidbits that can be used to determine what kind of content to serve the user.

For example, here's the user agent string for the latest version of Chrome (at the time of writing this article) running on Windows:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/139.0.0.0 Safari/537.36

The user agent strings of desktop and mobile browsers also differ. For example, here's a user agent of a mobile browser:

Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/139.0.7258.63 Mobile Safari/537.36

By changing the user agent string from the default one to the one that is used by browsers, you can make the website think that the request originates from a real browser and hide the fact that you're doing web scraping.

Also, you can rotate user agents to make browsers think you’re a real user.

How to Change Your User Agent?

Most of the HTTP client applications used in web scraping let you easily change the contents of the user agent string and, in that way, mimic using a real browser.

In this part, you'll learn how to do it with Requests , the most popular Python HTTP client library.

Let's say that you already have some code using Requests up and running.

import requests

response = requests.get("https://iproyal.com/")
print(response.request.headers)

To change the user agent that Requests uses, create a new headers variable that will contain a dictionary. The dictionary needs just one entry — the user agent header.

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/139.0.0.0 Safari/537.36"
}

Now you can pass the headers variable to the requests.get() function.

response = requests.get("https://iproyal.com/", headers=headers)
print(response.headers)

It will include the user agent in the request, overwriting the default header. The request will now have a user agent that matches that of the Chrome browser.

{'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/139.0.0.0 Safari/537.36', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive'}

Are There Any User Agents Specifically Designed for Mobile Scraping?

Just like desktop browsers, mobile browsers also have user agents that are specific to this browser and the operating system.

Here are some commonly used ones:

How Can Using Different User Agents Help in Bypassing Anti-scraping Measures?

By using a user agent that matches that of a browser, you can hide from preventative solutions that try to block traffic that comes from simple scraping scripts.

For example, Reddit can block requests which have the default HTTP client headers. Changing the user agent to virtually anything else gives you more possibilities to scrape the website.

In reality, websites monitor traffic patterns, user actions, IP address usage, and many other things to discern whether you're doing web scraping. It's essential to always stay on the top of your game, and just one small change in headers won't cut it.

One of the best ways to support large-scale scraping is through the use of rotating proxies . Proxies act as middlemen between you and your server, hiding the original IP address of your request.

When you rotate user agents throughout the scraping session, you can hide the fact that there is scraping happening at all — each request will have a different IP address, so it will look like there are just multiple users visiting the site.
