As a programmer (which is the requisite to build such tools even with LLMs), I have a plethora of tools to do the tasks, what I choose and how much time I invested in in that depends on something similar to this chart, but with an added dimension: interest.
Take for example the URL extraction. For one single occasion, I'd probably use VIM and macros to quickly do it. If it were many pages, I'd write a script. If it were infrequent, but recurrent, I'd take the time to write a better script and would only write a web page if the use case was shared with other people or if I wanted a cross platform solution.
I believe the first question one should ask before building is why. That leads you to find a better UX than shoehorning everything inside a web app.
