Chrome Automation w/o Keyboard Maestro Using Chrome Extension?

Are there any users in this forum that have experience performing Chrome browser automation without the aid of Keyboard Maestro (KM), but rather the use of some other Chrome extension?

Further Explanation:
I have several Chrome OS devices and I am unable to use KM on those devices.

I have used Kantu (now called UI Vision)

Not quite as user-friendly as KM but nonetheless very useful and very well executed software
