7 browser fingerprint quality checkers: testing the anonymity level of antidetect browsers

Before entering Facebook Ads from a new antidetect profile, it's standard practice to check it for data leaks. In some cases, the config turns out to be low-quality, and this needs to be fixed before starting farming or setting up ad campaigns.

We've compiled 7 popular browser fingerprint quality checkers that provide useful information about mismatches between fingerprint parameters and the actual device config. 

Disclaimer on Fingerprint Uniqueness

The arbitrage niche is full of myths that get in the way of productive work and waste valuable time. For example, many webmasters are convinced that every antidetect profile needs a unique fingerprint that will stand out in Facebook's database.

In reality, the better approach is a well-configured fingerprint that doesn't trigger Facebook's anti-fraud algorithms. The goal is to find the right balance between uniqueness and traffic volume. 

Experienced tech specialists recommend prioritizing uniqueness when a profile is just starting to be farmed and no cards have been linked to it yet. After that, everything depends on the account's interaction history with FB. 

Some webmasters, on the contrary, try to blend in among thousands of similar fingerprints and avoid giving ad networks any opportunity to establish connections between profiles from the same account farm. This approach has been proven in practice and needs no further justification. 

Ipdata

A useful service that assesses the "risk" level of an IP address. If the analysis returns a red flag, there are issues with the IP and you should reconsider whether it's worth farming from this proxy. 

What it checks:

• the organization managing the IP;
• association with anonymizers, VPN, and the TOR network;
• IP Trust Score.

Whoer

The service analyzes the anonymity of a browser fingerprint online. It delivers results as a detailed report with a masking quality score in percentage. We also recommend testing the DNS leak test tool.

What it checks:

• whether the IP appears in blacklists;
• functionality of key plugins;
• correct cookie transmission;
• DNS masking quality.

Browserleaks

A well-known service with an extensive set of tools for evaluating browser fingerprint security and privacy. The tests are designed to identify sources of data leaks about the device's real config and help fix the issue. 

What it checks:

• IP trust;
• DNS data leaks;
• Canvas / font fingerprint;
• functionality of standard browser HTML5 components.

AmIUnique

The service visualizes fingerprint uniqueness based on analysis of a large dataset. The report shows users how rare their fingerprint is — in our case, compared against a database of 2.2 million profiles. 

What it checks:

• HTTP/JS attributes;
• fingerprint uniqueness based on OS, browser, language, and timezone.

Pixelscan

Considered one of the most useful tools for checking browser fingerprint quality and uniqueness. With a single click, it analyzes hundreds of key attributes and generates a comprehensive report. 

What it checks:

• use of low-quality proxies;
• weak fingerprint masking;
• hardware fingerprints of the PC.

f.vision

This service is frequently referenced when there's a need to assess browser profile quality. It's recommended to use it in combination with Pixelscan to get the full picture. 

What it checks:

• browser component hashes;
• DNS server data leaks;
• whether the IP appears in blacklists;
• language and timezone consistency.

Iphey

The checker appeared on affiliates' radar not long ago, but it's already being called a flagship tool. It generates a report on the quality of browser masking, location, IP, hardware, and the software side of the device. 

What it checks:

• use of low-quality proxies;
• HTTP headers;
• presence of standard plugins.

There's no need to run your fingerprint through 5–10 services. Typically, affiliates bookmark 1–2 tools and run the checkers before logging into ad accounts. This allows them to spot potential data leaks in time.

Keep in mind that Facebook collects far more information than any affiliate tool can detect. That's why no antidetect browser guarantees 100% anonymity. FB's algorithms always operate with a long-term perspective, focused on collecting and continuously analyzing large volumes of data.
