Smartproxy proxy services

Smartproxy is a top-notch provider of premium proxy services on the market. Founded in 2018, it’s a huge favorite among individuals and businesses.

The company boasts an extensive network of 65+ million IPs in 195+ countries. These are hand-picked from ethical sources, perfect for enhanced user privacy and reliability.

Residential, datacenter, and mobile proxies are core to Smartproxy’s business. They offer a rich mix of features alongside pocket-friendly prices. 

Ease of use is another area where this vendor shines above the competition. It offers a simple dashboard accompanied by intuitive configurations to boost efficiency. 

Examples include the X Browser, which supports multi-user accounts for web browsing. There are also extensions/add-ons for Google Chrome and Firefox.  

Other features include developer-friendly web scrapers for search engines, e-commerce, social media, etc. Additionally, a no-code scraper is available for non-tech-savvy users. 

Let’s get up close with services. 

1. Residential proxies

Residential proxies are Smartproxy’s most popular product. It comprises 55+ million IPs available in 195+ countries. 

These come from real user devices attached to home broadband internet providers. This ensures they provide unmatched performance and reliability to the users. 

The Smartproxy supports geo-targeting based on countries. Moreover, you can filter results down to zip codes for the United States.  

Securing your residential proxies is super easy using username/password authentication. Whitelisting your device IP is another alternative that I found convenient.

Automatic rotation of IPs is available out of the box. Alternatively, you can set sticky sessions at 1, 10, and 30-minute intervals.

Multiple protocols are at your disposal to turbocharge your proxies. For maximum security, stick with HTTPS and SOCKS5 that encrypt connections. 

But if you value speed, HTTP provides faster connectivity and response rate. However, this option doesn’t shield your traffic against intruders. 

Running bulk tasks using Smartproxy won’t be a problem. The service supports unlimited concurrent connections and threads for managing projects at scale.

Away from that, Smartproxy bills you based on bandwidth consumption. As such, prices start from $4.5/GB and include traffic monitoring for tracking usage.

There’s also a three-day free trial to test the residential proxies before commiting.

Performance benchmarks

Smartproxy’s residential proxies don’t slack when it comes to performance. And my tests below are proof of this fact.

To begin, I ran around 100,000+ random location requests over seven days. Then I repeated the same, but this time, geo-filtered select regions.   

The results are as follows:

GatewayRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)
United States20,00019,9871399.94%1.06s
United Kingdom20,00019,79520598.98%0.57s
South Africa10,0009,9495199.49%1.10s
Performance Benchmarks

The results above are nothing short of impressive. The average success rate and speed for the sampled region speak for themselves.

However, Smartproxy’s promised figures of 99.47% and 0.5 seconds are slightly lower. But, the conditions during testing can cause the outcome of tests to vary. 

Based on the above, expect the residential proxies to deliver results with almost zero issues. 

Geo-targeting benchmarks

As I said earlier, Smartproxy supports geo-targeting. And during tests, I noticed discrepancies. 

Some mismatches showed up between the expected and actual proxy locations. The findings are as follows: 

GatewayRequests SentSuccessfulDiscrepancy% Successful% Discrepancy
United States20,00019,9435799.72%0.29%
United Kingdom20,00019,77023098.85%1.15%
South Africa10,0009,70429697.04%2.96%
Geo-Targeting Benchmarks

But there’s no cause for alarm as the discrepancies are almost negligible. As such, this won’t compromise the quality of results when using residential proxies.

I made 3,000 connection requests to each platform using US-based proxies. Again, I employed our in-house testing tool alongside third-party software like FOGLDN

GatewayRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)
Social media3,0002,9396197.97%1.41s
Performance with Popular Targets

From the above, Google recorded the lowest success rate. This means you should expect minor errors when scraping the search engine.

2. Mobile proxies

Smartproxy offers 10+ million mobile proxies for accessing websites with anti-proxy firewalls. You’ll also find them ideal for scrapping sites that target smartphone users.

Unlike residential, these come from devices hooked to cellular networks. Accordingly, they give you a high chance of evading IP blocks and CAPTCHAs online. 

Smartproxy offers geo-targeting based on countries and cities. You can also configure proxies by platforms like Android and iPhone.

Even better, filtering mobile carriers is an option as well. Coverage is impressive, with major country-based service providers available at your disposal.  

There’s IP whitelisting and username/password for authenticating your proxies. Another great addition is support for connection protocols like SOCKS5, HTTP, and HTTPS. 

But how do mobile proxies stack up?

Performance benchmarks

I sent about 45,000 connections using Smartproxy’s mobile proxies. The target was Cloudflare’s global CDN, which can handle tons of requests perfectly. 

The results are as follows: 

GatewayRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)
United States5,0004,89910197.98%1.20s
United Kingdom5,0004,84915196.98%0.86s
South Africa5,0004,9138798.26%1.59s
Performance Benchmarks

As you can see, Smartproxy’s mobile proxies perform exceptionally. They recorded a high success rate alongside impressive response speeds.

You’ll be able to handle data-gathering tasks with speed and precision. However, expect slight delays when targeting countries like Australia, India, and South Africa. 

Geo-targeting benchmarks

The quality of results is vital when targeting specific countries. That’s because discrepancies can negatively impact your ability to make proper decisions.

That said, here’s how Smartproxy’s mobile proxies perform. 

GatewayRequests sentSuccessfulDiscrepancy% Successful% Discrepancy
United States5,0004,82117996.42%3.58%
United Kingdom5,0004,11788382.34%17.66%
South Africa5,0004,88511597.70%2.30%
Geo-Targeting Benchmarks

Most countries generated reliable data with accuracies of above 96%. But the United Kingdom’s (UK) 82.34% outcome isn’t something you might want to deal with. 

17.66% of the proxy responses came from regions outside this target. This necessitates digging deeper into the data before making decisions.

However, network issues could’ve likely affected Smartproxy’s performance during testing. As such, results may differ depending on your setup. 

I sent around 15,000 connections using US-based mobile proxies. Each target received around 3,000 requests to ensure uniformity in analyzing data.

Check out the table below for the results.

GatewayRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)
Social media3,0002,9076196.90%1.36s
Performance with Popular Targets

Scraping e-commerce websites and social media platforms should be steadfast. But expect challenges for sites like Walmart and Google’s search engine.

The mobile proxy plans start from $7.50 GB/month. There’s also a non-expiry PAYG option that costs $20/GB. 

3. Smartproxy ISP proxies

Smartproxy recently added ISP proxies to its list of services. 

They come with 10,000+ IPs distributed across nine countries. The available ones are: 

  • The United States
  • Hong Kong
  • France
  • Canada
  • Australia
  • United Kingdom
  • Netherlands
  • Italy
  • Japan

These types of proxies come from internet service providers (ISPs). They’ve IPs hosted in datacenters for speedy connectivity and maximum reliability. 

Sadly, data from tests show they require fine-tuning. I hope Smartproxy performs the necessary optimizations to improve the accuracy of results.

Check the numbers below:

Performance benchmarks

I made 10,000 random connections for the initial test. Next, I sampled ISP proxies from six countries and sent 2,500 requests using each pool. 

GatewayRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)
United States2,5002,5000100.00%0.49s
United Kingdom2,5001,0061,49440.24%0.67s
Hong Kong2,5002,5000100.00%0.89s
Performance Benchmarks

ISP proxies are, without a doubt, super fast. Unfortunately, the performance took a tumble when it came to success rates.

About 60% of connection requests using the UK’s proxy pool failed. The same happened even after repeating the test three times. 

As for Australia and the Netherlands, the geo-filtering was off-target. The sampled proxies generated IPs in the United States, compromising the results. 

Geo-targeting benchmarks

As I mentioned above, Smartproxy’s ISP proxies seem to be experiencing issues with geo-filtering. A closer analysis of tests shows the problem affected all countries under review. 

Here’s what I discovered: 

GatewayRequests SentSuccessfulDiscrepancy% Successful% Discrepancy
United States2,5002,00449680.16%19.84%
United Kingdom2,5001,61788364.68%35.32%
Hong Kong2,50002,5000.00%100.00%
Geo-targeting Benchmarks

Only the United States recorded a discrepancy of below 20%. The rest of the regions registered terrible outcomes. 

Network issues might be to blame for such huge discrepancies. This is noticeably common whenever vendors introduce new products.  

I made around 2,500 requests to each target using US-based ISP proxies. The results? Exceptional. 

See for yourself: 

GatewayRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)
Social media2,5002,5000100%0.61s
Performance with Popular Targets

ISP proxies excel when scraping popular platforms. None of the requests to the targets failed. 

The response time is also faster than other Smartproxy services. This should come in handy whenever you’re running urgent tasks.

Plans start from $11 GB/month. You can also go with the IP-based pricing for $2.90 IP/month.    

4. Smartproxy datacenter proxies

Datacenter proxies are Smartproxy’s most affordable option. As the name suggests, they comprise 100,000+ virtual IPs hosted in data centers.

This makes them cheap, with prices starting from $0.60 GB/month. They’re ideal for scaling up your projects without breaking the bank. 

At present, Smartproxy offers a couple of data centers to choose from. These are as follows: 

  • United States
  • United Kingdom
  • Germany
  • Romania 
  • Netherlands

Datacenter proxies support the usual HTTP and HTTPS connection protocols. Unfortunately, only the US-filtered ones come with SOCKS5 authentication. 

You get static IPs by default during proxy setup. Alternatively, there’s the option for switching to automatic IP rotation.

Let’s look at how they perform. 

Performance benchmarks

I made around 60,000 connection requests using the US-based data center proxies. Like the other tests, the main target was Cloudflare’s CDN.

GatewayRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)
United States60,00059,994699.99%0.84s
Performance Benchmark

The results show impressive performance with an outstanding 99.99% success rate. The average response is not on par with ISP proxies, but it’s still remarkable. 

Accordingly, this service can handle data-intensive web scraping tasks effortlessly. Obtaining results will almost be instantaneous with minimum errors whatsoever. 

Download speeds

I tested three rotating and three dedicated IPs with the help of and Then, I leveled the results against my internet’s download speeds.

TestW/Out ProxyRotatingLatencyDedicatedLatency
Download Speeds

The rotating proxies are 15% faster than the more expensive sibling. The roles reverse regarding latency, where the latter shines by over 60%. 

Still, both record impressive speeds suitable for browsing, streaming, and downloading. But the costlier options give you better response time, ideal for online gaming.

I made an initial test comprising 15,000 requests using US-filtered rotating proxies. Afterward, I repeated the same process with static proxies. 

Each target received 3,000 connections for both the first and second runs. This ensured uniformity and consistency in analyzing data.

TargetRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)

Both performed amazingly well. However, static proxies experienced noticeable challenges with scraping Home Depot.

TargetRequests SentSuccessfulFailed% SuccessfulAvg Speed (Seconds)
Home Depot3,0002,84016094.67%1.02s
Static Datacenter Proxies

Chances are other Smartproxy users may have abused some of the IPs. This is nothing close to alarming, though.

5. Web scraping APIs

Developers can make good use of the web scraping APIs. They include dedicated scrapers for the following: 

  • Search engines’ results page (SERP)
  • Ecommerce
  • Internet/Web
  • Social media

The APIs only require you to provide the URLs for scraping. They can extract the necessary details and structure them into categories.

Pre-set configurations are available for SERP, ecommerce, and social media scrapers. The common ones comprise Google Search, Amazon, TikTok, and more. 

Moreover, you can set search queries to target specific keywords. Other options include providing links for user profiles on social media. 

There’s filtering based on geo-locations, device types, and web browsers. Even better, the Web API scraper supports configuring local languages depending on target regions.

You can make batch requests for data to turbocharge your scraping tasks. Once complete, data is downloadable in JSON, HTML, and PNG formats.

The pricing plans start as low as $2 per thousand requests. Additionally, Smartproxy offers a free trial bundled with 13,000 requests. 

The vendor promises a 100% success rate when using its APIs. So, I put it to the test to find out. 

Performance benchmarks

I launched 5,000 connection requests using Smartproxy’s SERP scraping API. The main target was Google Search using randomized keywords. 

The results? Almost perfect.

SERP API Benchmark

The SERP scraper API performed well beyond expectation. It fulfilled all requests with decent average response times.

For the second test, I deployed 1,000 requests using the Ecommerce API. This time, the popular online shopping platform, Amazon, was my target.

The outcome of this result was a resounding 100% success rate. Response time was also noticeably faster than the SERP scraper API. 

I ran a further 1,000 requests using the Social Media API to wrap up the tests. The main target was TikTok that’s flooded with tons of video content.
