Testing how Googlebot identifies itself.

This outputs information from the navigator API, such as userAgent.

It's interesting that it is Linux. I've seen a few so called "speed solutions" disabling resources if the device is Linux. They may be breaking the page for Googlebot!

Conclusion

We see the different user agent modifiers to identify Google-InspectionTool/1.0 and Googlebot/2.1. No surprise there.

I re-ran the testing tool a week after the real Googlebot and the Chrome version had already increased a bit. My Chrome is currently on 138, so it is a little behind. Googlebot's version when it crawled on 28 Jun 2025 was officially released 2 June 2025. The Google-InspectionTool version was run on the 7th July 2025 and it's version was released on June 17, 2025. So maybe it lags about a month.

It's not a real Nexus 5X, not surprisingly. The hardware concurrency is impressive, however ChatGPT thinks it is faked, or maybe they just have powerful servers. The memory is also not for a Nexus 5X but may reflect the memory allocated to that bot. The processor seems legit for a Nexus 5X. It's interesting that they still pretend to be a Google phone from 2016.
