Who wants the unwanted barriers while scraping publicly available data on the internet? Usually, when you make a scraping script to scrape and save data from websites like Amazon and Alibaba, it works fine, as long as you run it very often. But when this process is the basis of your business, and you need to scale scraping and collect massive data, your scraper may get blocked due to rate-limiting. Rate-limiting is the feature that blocks a user’s IP when the user sends requests to a website aggressively (too many within a short time).

That’s why businesses use residential proxies to scrape data. But sometimes, you do not want to worry about the blocking and need an advanced API that automatically rotates the IP address when it gets blocked. You need Bright data web unlocker proxy. 🏆

What is a bright data web unlocker?

Some websites on the internet are tough to reach, especially when you aim to extract data (at scale) for whatever purpose. 

Do you know what can help you to get that? The answer is pretty obvious now, and that is Bright Data Web Unlocker. 

Web Unlocker is one technology that can handle all site unblocking problems and deliver the data just as you expect. When you scrape data from a website like or, you need to ensure that you’re not blocked due to rate-limiting. To avoid blocking with the rate-limiting rule, you can use web unlocker. Web unlocker proxy will automatically rotate the IP address if the website blocks your scraper’s IP address.

This unblocking, extracting info, and structuring is all done via a bunch of automated protocols applied while attempting data collection. You can use a tool like Octoparse or Phantombuster. Bright Data Web Unlocker is excellent. But how does it work? Keep reading. 

How does Bright Data Web Unlocker work?

It’s pretty clear that web unlocking happens because of a series of automated protocols, but how does Bright Data make it possible? 

Why not look at the steps to understand its job more deeply? Here we go.

  1. As a user, you first signup to Bright Data and request the team to unlock a particular website or page. 
  2. This request is sent to the web unlocker algorithm that takes care of the rest. 
  3. What Web Unlocker Algorithm does is edit the request as required, mainly the header and protocol. This modified request is then sent to the Super Proxy. 
  4. Super Proxy is where all the proxy-related queries are shared with the main data infrastructure. You know how important this station is in the whole web unlocking journey. 
  5. Super Proxy shares the web unlocking request with the Bright Data Proxy Infrastructure. This infrastructure then used the user fingerprint on your behalf for visitor identification and goes to the target website. (Don’t worry, this has nothing to do with your personal information or identification.)
  6. The target website then shares the information to the Data Infrastructure, which goes to the Super Proxy, then Web Unclocker Algorithm, and straight to you, the user. 

This may look like an extensive, time-consuming process, but it happens so fast that you won’t find any delay in accessing your target website. All you need to do is make a simple request; the rest is Bright Data’s responsibility. 

You can integrate web unlocker proxy with your script in any language or software. 

No matter what you use for scraping (Shell script, Node.js app, PHP scripting, or Ruby software), you can generate the command/code using this tool.
