I am currently using several anti-detect browsers but I am not sure how to test if it is good or not. Are there any websites that show some data that can help to see weither or not the anti-detect browsers isolate the instances correctly?
Well, let's rephrase the question in a much different manner so people can understand the current blocking system for bots.
There are generally 4 types of groups in the botting world.
The first group is what we called the vendors, they are the sites getting botted and are usually a mix of airlines, banks, retail sites, government sites, social media sites, etc. You get the point!
The second group is what we called the Anti-Bots, they are the groups in charged of protecting the endpoints and infrastructure of the vendors. They include companies like Akamai, Cloudflare, PerimeterX/Human, Imperva/Incapsula, Datadome, Kasada, ShapeSecurity, Hcaptcha, Recaptcha, Geetest etc. These groups usually deploy a sort of Nginx/Caddy/Apache plugin or SDK, and install their unique Javascript protection on the vendors site.With the exception of Google and a few other huge sites, almost every single site is protected by one of these Anti-Bots.It is also important to notice that I include the captchas companies with the anti-bot companies due to their similarities in functionality as they are there to protect their clients assets from cyber attacks.
The third group is what we called the Bot Tool Makers and they include things like github open-source projects, anti-bot api services by someone from sneaker dev, anti-detect browsers by someone from BHW, and the occasional bot you find on other forums and the open web. These tools are usually delivered through 2 ways, either through a custom build up chromium/firefox buildt into a branded application that is then sold thru various forums cough cough BHW cough cough, or through api services sold thru discord servers that provide the fingerprint/sensor data/ cookies for specific anti-bot apis.
The fourth group is the botters, these are the users that are trying to get something by force from the first group, whether that is publicly available data, automated checkout purchase, or something even more maliciously like account take overs.
This last group usually consists of 3 main people, the people that don't got time to spent bypassing an anti-bot and they have a business that depends on bypassing the people from the second group, the anti-bots, they are willing to throw money at solutions that gets them there. The people with no money to spent that usually come from 3rd world countries with a super low budget , they will usually resort to open-source solutions and then maybe end up paying for the low tier anti-detect browsers. The last person in this group are those that are usually doing massive amounts of web scraping on different web properties and that they are getting blocked by the anti-bots, they are anything from academics to someone with a massive scraping idea.
The problem with the people on the Fourth group is that majority of them are lacking self awareness of how clueless they are on how the people on the second group are blocking their futile attempts to get to the people on the first group. They resort to these open-source sites like retards where they check some imaginary score that makes them believe they are passing some sort of magical gate that will allow them to bot their site successfully.
Not all Anti-Bots are built the same, you have the suckiest ones from DataDome all the way to the gold-standard that is ShapeSecurity, a lot of them are in the middle in terms of difficulty. And there lies the problem, that the majority of the people on the fourth group have zero freaking idea of how these websites are protecting themselves from them. They think that by buying "anti-detect" browsers that they will be unable to get detected by the site's anti-bot measures.
Buying and anti-detect browser and expecting to bypass a site's security is like getting a lawyer and expecting it to be a 100% Get-Out-Of-Jail card. It just doesn't exist, that is a made believe lie that has propagated through many forums. In order to get through a site's honey you must first defeat the anti-bot systems, not change your browser properties a la dumb like a dummy would.
You need to check everything from you http2/tls fingerprint to your Javascript fingerprints for that SPECIFIC antibot. Let me rephrase FOR THAT SPECIFIC ANTIBOT, let me repeat it so it can be ingrained into your tiny brains people from the fourth group.
IN ORDER TO BYPASS A SITE'S PROTECTION YOU NEED TO BYPASS THE SPECIFIC ANTIBOT THAT IS FOUND ON THEIR SITE.
The beauty about this though is that because the web is usually protected by a handful of anti-bot companies, if you find a site that is protected by one anti-bot company and you can bypass that anti-bot, then you can usually bypass the other sites with that anti-bot company.
For example, if you can bypass Nordstrom's then you can also bypass END Clothing, Tiktok, Target, and some other important logins.
