Note that this conflicts with #3919.

And duplicate code, which make it hard to maintain in the future. If I want to fix bug of this I have to fix it 2 times.

Those new features in real-browser such as remote browser and enlarge image I believe they are not available for this due to duplicate code.

According to our pull request rules, we should have a discussion on how to design it first.

Hi @bthurlow, any chance you can get into discussion with Louis ? I would really like to see that feature in Uptime Kuma.

BR and thanks for your efforts

@louislam If it suits you, once I can get back on this code base, I'll see about consolidating all the keyword code into a single method to make management and reuse much better.

Extracting keyword and other checks is tracked in #3919
I think closing this PR is better. @chakflying do you agree?

@bthurlow thanks for your work.
I am going to close the PR, as in the current state it is just not maintainable.
If you consolidate this into one monitor, we can reopen the PR or start of fresh in a new PR ^
