App that tracks prices on websites? (lemmy.world)

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!

A tool that can track price changes on any website automatically is difficult since there isn't a standard way that prices are presented on a website. As has already been said, changedetection is your best bet

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.

There is a Firefox adding that can load a page amd extract a div, and track it over time. But the browser needs to be open. It is called PageProbe

I used it to track the price of an item, looking for a sale.

edit - updated the name and added link

Change Detection can be used for several use cases. One of them is monitoring price changes.
