How it works
Paste a URL
Any public page — your own site, a pricing page, a policy, a changelog.
Optionally target an element
Add a CSS selector to watch just the part of the page you care about.
Get useful alerts
Email alerts when a page changes, AI summaries of changes in your dashboard, plus uptime and recovery alerts. Slack and webhooks on paid plans.
You choose which alerts each URL sends — downtime, content changes, slow responses — and we email you when they happen.
What Site Monitor offers
- Content change detection for a whole page or one element
- Plain-English AI summaries of what changed
- Uptime, recovery, and response-time alerts
- Broken-link checks and screenshot history (paid plans)
- Public status pages and an embeddable status widget
- A Free plan: 10 URLs, hourly checks, 2 AI summaries a month
Watch one element instead of the whole page
Add a CSS selector to a monitor and Site Monitor only compares that part of the page — a price, a table, a list of dates. Rotating banners, timestamps, and ads elsewhere on the page stop triggering alerts.
Know what changed without reading a diff
When a monitored page changes, Site Monitor emails you, and its AI summary in your dashboard explains the change in plain English — a new date added, a price that moved, a clause that was reworded — so you can decide quickly whether it matters.
How to choose a website monitor
Start with what you need to know. If you only care whether a site responds, a basic uptime check is enough. If you need to know what changed on a page — a price, a policy clause, a list of dates — look for content change detection and element (CSS selector) targeting.
Then consider where checks run (in the cloud or on your own machine), how often you need them, how alerts reach you, and whether you want summaries of changes or raw diffs. Trying two tools side by side on the same URLs for a week is the most reliable way to decide.
Frequently asked questions
Is Site Monitor free?
Yes. The Free plan covers 10 URLs checked hourly with 2 AI summaries a month — no credit card required.
Can I import monitors from another tool?
There's no automatic import, but adding a URL takes a few seconds — paste the URL, optionally add a CSS selector, and you're done.
Will rotating ads, timestamps, or counters cause false alerts?
Not if you scope the watch. Add a CSS selector (for example #pricing or .event-list) and Site Monitor fingerprints only that element — everything else on the page is ignored. Whitespace-only changes never trigger an alert.
What is an AI change summary?
When a page changes significantly, Site Monitor uses AI to describe in plain English what was added, removed, or reworded. Summaries appear in the site's dashboard — your email alert links straight there. The Free plan includes 2 AI summaries a month; paid plans include more.
How often does Site Monitor check a page?
Free checks every hour. Paid plans check as often as every 5 minutes, and you can set the interval per URL.
