I built a website change monitor that still works when CSS selectors break

Hey Product Hunters!

Problem: Many website change monitors break silently when pages are JavaScript-heavy or when the DOM structure changes.
FetchTheChange is my attempt to fix that. It monitors any value on a page (not just prices) and—when a selector stops matching—helps you recover instead of failing silently.

Key features:

• Works on modern, JavaScript-heavy sites

• Monitors any value (prices, availability, metrics, text, status messages)

• Shows clear failure states (e.g. “selector missing” vs “blocked”)

• Includes a built-in “Fix Selector” helper that suggests working selectors

Here’s a screenshot of the selector-fixing flow:

I’d love honest feedback:

• Would you use this? For what use case?

• Is the “Fix Selector” flow clear enough for non-technical users?

• What would you need before paying for it?

Happy to answer any questions — thanks for taking a look!
