It saddens me to read some of the "no" responses, since I just shipped a few days ago exactly the type of small web app that OP speaks of. I personally find it really useful and wished I had this tool every single time at work. And the original version I made for the Mac App Store 10 years ago was a huge hit, placing in the top 5 rankings for over several weeks worldwide.
As I've grown older, I like to pay for things that make my life more efficient. Even if they are a subscription, and even if I feel like everything unfortunately has turned into a subscription and even if I feel like it should be cheaper. Hacking or finding workarounds to achieve the same thing for free is just not worth my time, and I value my time and boundaries more as I age.
