Are anti-detect and stealth browsers still largely working in 2026?

flatdiskprod · Apr 30, 2026

I came across an interesting post and wanted to get some more insight from the community on the experience they're seeing across browser stealth automation now. My research suggests most stealth browsers are fine for most read heavy usecases (scraping). But for use cases that need an account they're more flaky and can be detected. But ultimately the proxy ip quality is the biggest red flag not really the browser.

Can chrome detect chromium forks... short answer yes. They dont compile Google Chrome like they do Chromium and any copy of Chromium is also inherently compiled differently. While Chromium is open source, Google Chrome's specific compile procedure is not, it's incredibly custom as its deployed to billions of devices. And they have a huge incentive to can differentiate their own browser for fingerprinting purposes.

Estimates not put Chrome at over 1000 unique signals they use as part of fingerprinting. Mindblowing stuff!

The read-only vs. account-management split is real. For scraping, Playwright-stealth or undetected-chromedriver still handles most targets — exceptions being platforms running aggressive JS challenges (Cloudflare Enterprise, DataDome, PerimeterX). For account work, managed anti-detect browsers like GoLogin, Dolphin, and Multilogin inject runtime patches for the Chromium compile-mismatch you're describing and are mostly keeping up for mid-volume use. Where they fall apart is high-volume farming or platforms that push detection updates weekly. IP reputation is still the biggest unlock — get that wrong and it doesn't matter how clean your browser fingerprint is.

Good breakdown on the Chromium compile-mismatch angle — that's genuinely underrated as a signal source compared to how much attention canvas/WebGL fingerprinting gets.

One thing that doesn't come up enough in these threads: DNS/ECS mismatch. Even with a perfectly clean IP and correct WebRTC, if your DNS resolvers route through a different ASN than your proxy's ISP (extremely common — most proxy providers don't control resolver routing at all), fraud scoring flips hard. We've tested this on fresh residential proxies where IP + WebRTC matched perfectly but resolvers still traced back to a datacenter — fraud probability jumped from single digits to 80%+ on otherwise identical requests, and it's repeatable, not noise.

Manually forcing ECS to match the IP subnet doesn't fix it either — in some of our tests it actually made detection slightly worse, presumably because the mismatch pattern itself becomes a secondary signal.

So I'd push back slightly on "it's all IP reputation" — IP is the biggest lever, agreed, but DNS/ECS congruence is a close second, and it's the one almost nobody checks before buying.

the compile mismatch is definitely a massive hurdle but people also forget about TLS and HTTP/2 fingerprinting. you can patch chromium all you want to mimic chromes JS engine, but if your JA4 fingerprint or HTTP/2 frame settings dont match what a real windows chrome client sends, akamai or cloudflare flags it instantly before the JS even runs. in my experience thats why so many stealth setups fail on signup pages even with clean residential IPs. it is just a massive cat and mouse game...

Yeah, it seems like all the major anti-detect browsers are still working. I'm using a few of them at the same time. Have you heard about Vision? It's the fastest one out there at the moment.

I have tested some with the anti-detect, the Dolphin one seems the most commercially available. I know they are concerning privacy, though is it better to use it for multi-accounting? Obviously it allows you to create more accounts one by one by different profiles for the platform targeted. Is there any good result mixing this anti-detect tech with automation? I remember the Jarvee bot I missed out on, the account structures and people using SIMs to make accounts here. With Dolphin is it fast in a legal method to do accounts bulk is all Im wondering.
