which antidetect has the biggest browser fingerprints database?

& most up-to-date & accurate

And where did they get those data?

Hard to say who has the biggest database since most of them don’t share that info, but from using a few, AdsPower and Multilogin usually do a pretty good job with realistic fingerprints. I’ve found it’s less about how many they have and more about how natural the profiles actually look. Sometimes tweaking things manually works better than relying on presets.

According to my observations, AdsPower and GoLogin are superior in terms of sizable databases of browser fingerprints. In particular, AdsPower uses a large range of real-world configurations, which facilitates spoofing. However, it depends on your use case; some people value customization over quantity when it comes to Multilogin.

Using AdsPower, probably the cheapest option while still be reliable, 2nd is GoLogin you can try for free

The anti-detect browsers with the most comprehensive and frequently updated fingerprint databases are Multilogin, AdsPower, and GoLogin. It’s not just about volume, but how fresh and realistic the fingerprints are?including user-agent, OS, screen size, WebGL, canvas, fonts, and more.
Where do they get the data from?
– In-house crawlers scanning the web and collecting real-world user setups
– Public datasets from tools like WhatIsMyBrowser, DeviceAtlas, FingerprintJS
– Reverse engineering browser behavior via JavaScript across target platforms
If you're after maximum realism, Multilogin is slightly ahead in fingerprint quality, but AdsPower and GoLogin are very close,and more affordable for large-scale setups

All anti-detect browsers work with the same underlying technology. It is just a matter of extra features and convenience that makes the difference. Such as : cloud sync, team members, automation api etc.

For me, no antidetect publicly shows the exact size of their fingerprint database, so it really depends on how often they update and how natural the fingerprints are. Multilogin has been around for a long time and is pretty solid in this aspect, though some say updates can be slow. Hidemyacc is a newer option but they do push fresh fingerprints quite often and cover various devices and OS versions too.
Most of these tools get fingerprints by collecting real browser and device configs or buying big data sets, then tweaking them so they look legit. If up-to-date fingerprints matter, best bet is to choose one that updates frequently and gives you options to adjust details yourself.
