Just came across this, and thought it was a pretty cool tool to self-host. You can use it to monitor price changes, or new events being added, or to check if that out of stock thing is back in stock.

I use this fairly often. Simple, effective, no complaints really.

Great tool, been using it for a while. I get my notifications via RSS. Wish I could figure out how to make it detect prices on Amazon though, that doesn’t seem to work. And some sites just block it completely requiring a proxy/captcha solver.

For plain text files, such as changelogs and translation updates, I have a pull request that makes FreshRSS track diffs, without overhead of a full browser: https://github.com/FreshRSS/FreshRSS/pull/8107

ChangeDetection does not necessarily need a browser and can be run without, but can do more with it (e.g. bypass some bot protections or even do some steps on the website, like filling a form, before checking for changes).

Yeah, more specifically it runs headless by default, browser requires an additional chromium container. Perfectly usable without in most (of my) use cases

I could never get this to work right nearly every website would fail because of captchas

OpenAltFinder@lemmy.world on 19 May 20:08 next collapse

Yeah, that’s always a struggle with scraping, lots of sites don’t like it, even if you try and be respectful.

Depends if your outgoing is a local address or if you’re going through a vpn.
I rarely run into the issue on the former, almost always on the latter.
I think there’s a way to hook a solver on top of it, but I could be mistaken, haven’t done so myself.

i used this in the past. is pretty neat and has various ways of notifying you about the change, ever discord notifications

Very nice project!

halm@leminal.space on 20 May 00:57 next collapse

The better alternative would be if all sites just had RSS feeds… but yeah, since we can’t have nice things, this is the way to keep tabs on site updates!

OpenAltFinder@lemmy.world on 20 May 22:34 collapse

Yeah, I remember it used to be standard to have an RSS feed, these days it’s pretty rare, sadly.

I’ve been running this for years and it’s great. Does what it says and it’s really awesome to have a tool like that

BrightCandle@lemmy.world on 20 May 11:34 collapse

Takes a little bit of setup on some sites where you want to narrow the text to article headers or such but its a really versatile tool for tracking websites without RSS. What I wish it did a bit differently was how you subscribe to the actual feed and how it presents the changes, I would like to be able to customise that presentation more.
