DiffWatch
Change monitoring, minus the checking

You stop checking. We tell you the moment it changes.

DiffWatch watches the pages that matter to you — prices, listings, filings, docs — and pings you the second one moves, in plain words.

How it works

Three steps, then forget about it

No browser extension, no dashboard to babysit. It runs on our servers and only speaks when something actually changes.

  1. Step 1
    Tell us what you're waiting for
    Paste the page and name the part that matters — a price, a deadline, a stock badge. We'll watch just that.
  2. Step 2
    We watch on schedule
    Hourly on Free, every 15 minutes on Pro. We ignore scripts, styles, ads and timestamps, so only real changes count.
  3. Step 3
    You get told, in plain words
    An email that says exactly what changed, with a link straight back to the page.
Features

Built to be trusted, not just installed

The unglamorous details that make a watch you can actually rely on.

Watch the part that matters

Point DiffWatch at the price, the deadline or the stock badge. Everything else on the page can churn freely.

watching: the price

Quiet by design
Only real changes reach your inbox. Cosmetic churn and repeat alerts never do.
Checks that keep up
Every 15 minutes on Pro for pages that move fast — prices, restocks, live listings.
Pages or data feeds
Websites and public data feeds both work. No browser, no extension.
Set up in a minute
Paste, pick a schedule, close the tab. No crawling config or runbooks.

Cheaper than your time

Manual refreshing and your own scripts both work — until they quietly stop.

Who it's for

For anyone who refreshes a page for work

If you keep a tab open and hit reload, DiffWatch can hold that tab for you.

Prices, plans & stock
Know the moment a competitor or supplier changes a price, a plan or a stock status.
Tenders & grants
Portals rarely announce updates. Watch the results page and get told when it changes.
Listings & job boards
Catch a new listing or a back-in-stock page before everyone else does.
Terms & docs
Track the pages that quietly change and affect your compliance or integration.

FAQ

Questions, answered

No. Paste a URL in the dashboard and we check it from our servers. There is no browser extension and no script to embed.

Alerts fire only when the content genuinely differs. Cosmetic noise and repeated changes are filtered out before we compare.

Most websites, yes. We read what the site's server sends, which covers most shops, portals, boards and docs. A small number of very modern sites build the page in your browser and show us nothing — tell us the URL and we will confirm before you rely on it.

Not yet. Pages behind a login are on the roadmap. Today we watch public pages only.

We compare the page's real content and alert only when it genuinely changed — never for cosmetic churn or a page reload. A real alert is a real change.

Yes. Cancel from the billing portal and your account returns to the Free plan at the end of the current period. Free needs no card at all.

Stop refreshing. Start watching.
