Hello fellow self-hosters! I am looking for an app/tool/macro/etc that can screen-scrape or API ping various merchants to track prices on specific products. Think camelcamelcamel but for any merchant. I have to believe such a tool exists and I’m not the first person to think of it.
In an ideal world, I’d like it to be able to dump the data into a spreadsheet so that I can track/graph it. But that’s not a requirement.
Does such a tool exist?
Thanks!

Change Detection can be used for several use cases. One of them is monitoring price changes.
This sounds like a dream for me, what I found was even better, was making a slick deals account and setting up an alert for exactly what I needed. That way I wasn’t mindlessly shopping and buying unnecessary things! Following this thread though cuz I’m interested!
Same. Slickdeals and forget it. The website is a bit of a privacy nightmare w/ inserted tracking/referral links for every deal though. I’ve stopped logging in entirely and just use it for emailed alerts.
I used browser extension Distill in the past, it’s pretty easy to use and it works well for detecting/tracking changes of the specific elements on the page. I think free version allows 25 local monitors.
I also just found this extension Automa, I’ve never used it, but it seems cool. Looks like a Tasker for your browser. And there are also a workflows that people share, I saw this one randomly, Scrap Google Suggest to SpreadSheet so I guess you could do a similar thing for prices.
Yeah I saw the Google sheets scraping tool and that looked promising but I don’t want to have to rely on Xpath since it could change.
Right now I’m leaning toward change detector but can’t get the reverse proxy to work.
