Anybody noticing increased detection rate recently?

For e.g: I'm getting detected instantly on owler.com/company/chevron

Started happening about a week ago only.

yep, stopped working at patreon.com too

Looks like cloudflare rolled out something targeted at detecting pupeteer instances somehow.

Any ideas @berstend?

Time to be the mouse again 😅 and try to one up the cat.

The problem is the source code in this repository is open to public and people from cloudflare can easily see it. So far cloudflare+hcaptcha works well. 🤔

This site as well is being detected, looks like it is cloudflare as well. Just upgraded to latest puppeteer and latest stealth plugin (2.6.0) and still being detected.

There's a big update coming tomorrow that might help with this :-)

Currently every headless browser can be detected with Array.isArray(navigator.plugins) (or the absence of navigator.plugins). I finished a complete rewrite of navigator.plugins & navigator.mimeTypes today that does a fully functional and native appearing mock of these properties. 😄

AFAIR that's a check CF is doing.

Need to clean up some docs and will push (and publish) this tomorrow.

On the bright side: It forces us to build clean solutions over time, rather than just quick patches 😄 We're definitely entering the next stage of this cat & mouse game where implementation details are much more important.

We've made some massive updates (#291, #292, #297) which should fix the Cloudflare issues, please check with puppeteer-extra-plugin-stealth@2.6.1 and report here if there are more Cloudflare specific issues (ideally with the JS they're using).

That sounds super exciting, gonna test. :D
