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.

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!

Very nice project!

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

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.

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

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

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

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).

[-] filcuk@lemmy.zip 2 points 5 hours ago

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

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.
