Headers are easy to alter with cURL, and copying the User-Agent header of a legit browser could do the trick. But it is not difficult to artificially forge an HTTP request with cURL or any library to make the request look exactly like a request made with a browser.

Everybody knows this. So, to determine if you are using a real browser, websites will check something that cURL and library can not do: executing Javascript code. Once again, this solution is not completely bulletproof, mainly because it is now very easy to execute Javascript outside of a browser with Node. However, the web has evolved and there are other tricks to determine if you are using a real browser. Trying to execute Javascript snippets on the side with Node. And more importantly, as soon as the website has a more complicated check system or is a big single-page application cURL and pseudo-JS execution with Node.

So the best way to look like a real browser is to actually use one. Headless Browsers will behave like a real browser except that you will easily be able to programmatically use them. The most popular is Chrome Headless, a Chrome option that behaves like Chrome without all of the user interface wrapping it.

The easiest way to use Headless Chrome is by calling a driver that wraps all functionality into an easy API. Selenium Playwright and Puppeteer are the three most famous solutions. However, it will not be enough as websites now have tools that detect headless browsers. This arms race has been going on for a long time. While these solutions can be easy to do on your local computer, it can be trickier to make this work at scale. Managing lots of Chrome headless instances is one of the many problems we solve at ScrapingBee.

Everyone, especially front-end devs, know that every browser behaves differently. Most of these differences are well-known and it is now possible to detect if a browser is actually who it pretends to be. This is why there is an everlasting arms race between web scrapers who want to pass themselves as a real browser and websites who want to distinguish headless from the rest.

This means that the Javascript will behave nicely inside a scanning environment and badly inside real browsers. Web scrapers can profit from this effort. Another thing to know is that while running 20 cURL in parallel is trivial and Chrome Headless is relatively easy to use for small use cases, it can be tricky to put at scale. Because it uses lots of RAM, managing more than 20 instances of it is a challenge. By the way, if you still want to use cURL to scrape the web, we just published a guide on how to use a proxy with cURL , check it out.

This protocol ensures privacy and data integrity between two or more communicating computer applications in our case, a web browser or a script and an HTTP server. Similar to browser fingerprinting the goal of TLS fingerprinting is to uniquely identify users based on the way they use TLS. First, when the client connects to the server, a TLS handshake happens. During this handshake, many requests are sent between the two to ensure that everyone is actually who they claim to be.

Then, if the handshake has been successful the protocol describes how the client and the server should encrypt and decrypt the data in a secure way. If you want a detailed explanation, check out this great introduction by Cloudflare. Most of the data point used to build the fingerprint are from the TLS handshake and if you want to see what does a TLS fingerprint looks like, you can go visit this awesome online database.

On this website, you can see that the most used fingerprint last week was used This number is very big and at least two orders of magnitude higher than the most common browser fingerprint. It actually makes sense as a TLS fingerprint is computed using way fewer parameters than a browser fingerprint. If you wish to know what your TLS fingerprint is, I suggest you visit this website. Ideally, in order to increase your stealth when scraping the web, you should be changing your TLS parameters.

However, this is harder than it looks. Your fingerprint will be so rare that it will be instantly flagged as fake. Secondly, TLS parameters are low-level stuff that rely heavily on system dependencies. So, changing them is not straight-forward. Here are a few resources to change your TLS version and cypher suite in your favorite language:. Keep in mind that most of these libraries rely on the SSL and TLS implementation of your system, OpenSSL is the most widely used, and you might need to change its version in order to completely alter your fingerprint.

A human using a real browser will rarely request 20 pages per second from the same website. So if you want to request a lot of page from the same website you have to trick the website into thinking that all those requests come from different places in the world i. P addresses. In other words, you need to use proxies. One thing to consider is that proxy IPs needs to be constantly monitored in order to discard the one that is not working anymore and replace it.

Free proxy lists are usually public, and therefore, their IPs will be automatically banned by the most website. Proxy quality is important. Anti-crawling services are known to maintain an internal list of proxy IP so any traffic coming from those IPs will also be blocked.

Open Tor on your computer. This assigns you a new IP. If you already have a website open and want to change your IP address, read on. A pop-up window will appear, warning you that Tor will close all windows and tabs. If you just want a new IP address for the site you have open now , not everywhere on Tor, select New Tor Circuit for this site from the menu instead.

Click Yes to restart. Tor will shut down and re-open, acquiring a new IP address during the process. Now that you have a new IP, the sites you visit will see this IP rather than your previous one. If you want to specify which country your IP address is in, you can specify a region using Strict Nodes. Include your email address to get a message when this question is answered. When changing your IP address in Tor, the change only affects Tor and not other programs on your computer.

Helpful 0 Not Helpful 0. Tor has three security levels—Standard, Safer, and Safest. Tor recommends not installing any browser add-ons to avoid accidentally compromising your anonymity.
