The new headless Chrome has been released in November 2022. For the moment, it hasn’t become the standard headless mode. It’s still hidden behind a –headless=new flag. However, it will soon become the standard headless mode, and this is going to change a lot of things when it comes to bot detection, particularly detection based on browser fingerprint.
Antoine is the head of research at DataDome, a bot detection company, so he knows what he’s talking about here. The good news is you can still detect the new headless Chrome, but it will be more tricky. The other good news is that fingerprinting is just one of many tools in the bot detector’s belt. Others include request behavior, reputation scores, proxy detection & TLS fingerprinting.
