Love these kinds of projects! To me they represent what's the most fun in programming. Here's a couple of mine: * During COVID lockdowns, the local grocery chain delivery slots were reserved a week or more in advance, but they were opening up a few slots each day; I wrote a scraper that would detect a newly opened slot and ping me on Slack, saving me a few days' wait on each delivery. * When I was buying a house, I wrote a scraper that would email me daily with what was new on the market; didn't end up buying through that, but I later repurposed it to check for used car classifieds and snatched a pretty nice deal.
