I was manually checking a competitor's website every day. So I built something to stop doing that.

This is a little embarrassing to admit.

For months, I had a tab pinned in my browser. A competitor's pricing page.
I'd open it every couple of days, stare at it, try to remember what it
looked like last time, and close it.

No system. No alerts. Just vibes and a bad memory.

Then I missed something. They quietly changed their pricing for a week —
a promotion I only found out about after it ended. By the time I noticed,
the window was closed.

That was enough. I decided to stop doing this manually.

I looked for a tool. Nothing felt right.

The options I found were either:

• Overkill enterprise tools with pricing to match
• Abandoned projects that hadn't been touched in years
• Too technical to set up without writing scripts

I didn't want to write scripts. I just wanted something to watch a URL
and tell me when it changed.

So I built it myself.

Introducing ChangePulse

ChangePulse monitors any public webpage and
alerts you the moment something changes.

You paste a URL. Pick how often to check it. Choose how you want to be
notified — email, Slack, or webhook. That's it. ChangePulse handles
everything else and sends you an alert with a visual diff showing exactly
what changed and what was there before.

No scripts. No server. No manual refreshing.

The use cases surprised me

I built this to solve my own competitor monitoring problem. But since
launching I've heard from people using it for things I didn't anticipate:

• Watching company career pages to catch job postings the moment they go live
• Tracking supplier and vendor pages for price or stock changes
• Monitoring government and regulatory pages for policy updates
• Keeping an eye on a product page waiting for a restock
• Agencies monitoring competitor pages for their clients as a value-add

The common thread: people who need to know when something changes, but
don't want to babysit a browser tab to find out.

It's free to start

There's a free plan with 5 monitors and daily checks. No credit card,
no commitment.

If you've ever found yourself manually refreshing a page waiting for
something to change — this was built for exactly that moment.

What websites do you find yourself checking manually that you wish you
could automate? Curious what use cases I haven't thought of yet.
