Since I took a break from marketing around 2022 anti-detect browsers seem to be the new craze.

I have been seeing lots of mentions on marketplace about adspower which seems the hot one on the block but looks like a subscription type of thing.

What open source equivalents are there and are they really a big advantage over what used to be the usual way of doing things which was just firefox or your usual browser of choice and switch user-agent and keep the proxy linked to that browser? I am reading they use other detection methods now such as webrtc which is new to me so is that no longer enough and better to use one of these specialized anti-detect browsers?

If so what is an open source one which is well regarded? no intention of paying for such services? or how to achieve the same yourself without paying? I just searched 'open source anti-detect browser' and camoufox came up as one of the first results. Is that one good or which do you recommend?

Open source options can work for learning and testing, but they usually require more technical knowledge and maintenance. Paid tools became popular because they package fingerprint management, profiles, and team workflows into one place. For serious operations, reliability is usually the deciding factor.
 
Adspower gives 3 or 2 free. Use a combination for free profiles from 3-4 browser apps.
Open source anti detect browsers dont maintain their code and they fall apart. They stops working.
All paid ones regularly update and maintain they code.
 
The issue with open source is the updates; every update the Chromium engine needs to be inspected to see if it leaves additional fingerprints. Most projects start ambitiously then stop because it's difficult to main that level of update rate for free.

So is just a separate profile on your preferred browser such as firefox, with user agent changed in prefs.js and proxy linked only to that not enough these days? I am wondering why you can't change these things manually using just a standard browser and keep that profile saved on your machine so it doesn't change each time you load it up?

That is how it was done up to like 2022 when I stopped and before. I am wondering what has changed since then - if these paid anti detects are just another money spinner that is not needed if you don't mind doing the work yourself to set your own profiles on normal browsers.
 
@slopppyfart the big change is UA became one tiny piece of the puzzle. If you change UA in Firefox but fonts, canvas, webgl, timezone, screen size, webrtc, language, client hints etc don't line up, it can look more weird than not changing anything.

You can still do manual profiles for small stuff, sure. But the annoying part is keeping the whole fingerprint coherent after browser updates. That’s basically what the paid tools are selling, not magic. Camoufox is decent to mess with imo, but I wouldn’t treat any open source antidetect as “set and forget”.

Not sure about opensource, but if you’re looking for something easily manageable take a glance at either Dolphin Anty or Incognito, they’re both solid and have a free tier.

Free tier? Maybe I'll give these a try then.

The issue is what is being fingerprinted today. Your webcam model. Your GPU model. How many microphones you have. How many output audio devices you have. How quickly you render text, etc, etc. This is not just changing a setting anymore - the change needs be hardware-consistent with someone else's hardware. The worst outcome is to generate a 100% unique fingerprint because that's 100% detectable due to uniqueness. You want a fingerprint that blends in with real traffic - that's the issue.

If that wasn't enough - checkout Google's blog on Chrome updates. Every single version comes with a new web standard that adds new fingerprints. It's all on purpose.
 
opensource in anti-detect means it’ll be easily patched/spotted by the platforms you’re trying to run accounts on. I’m using adspower mostly, costly but decent.
 
Best to use something premium instead of open source because of fingerprint management and maintenance-free benefits. But if you want to go 100% free and better than paid, at least as they said, then try Cloak browser. I wonder why anyone hasn't mentioned it, but it's great if you're techy or, like others said, download a few browsers like dolphiny , incogntigo , adspower etc
 
Camoufox looks like the obvious one to try first

Just changing the user agent won’t do much on its own though. Proxy location, timezone, WebRTC and screen size should all match or the profile can still look weird
 
Anti-detect browsers have evolved way beyond just spoofing user agents they mask canvas fingerprints, WebRTC leaks, and dozens of other signals that modern platforms use to detect multiple accounts. Camoufox is legit and well-regarded in the open-source space, built on Firefox with solid fingerprint spoofing baked in.

Hi, I was wondering if AdsPower offers any promotions or discounts. The free plan is a great way to get started, but the limit of 2 browser profiles is quite restrictive for my use case. I'd appreciate it if there are any available offers or discounts.
 
Yes, anti-detect browsers have become much more useful since 2022.
Changing only the user-agent and proxy is no longer enough because websites use advanced browser fingerprinting.If you want a free and open-source option, Camoufox is one of the best-known choices.For most users who need multiple browser profiles, it's the strongest open-source alternative to paid tools

Seems like a good choice and I am used to using firefox as my main browser which helps.

Just keep an eye on the in-app notifications. If there's a promotion or discount, you'll usually see a pop-up in the client.

Maybe in a few more years we will all have our own anti-anti-AI-bot-bots to counteract them.
