How it works

  1. Nothing to host

    No server, container, or headless browser to maintain. Sign up and paste a URL.

  2. Target with CSS selectors

    Watch a whole page or just one element.

  3. Read plain-English summaries

    Get an email when a page changes; AI summaries in your dashboard explain what changed.

You choose which alerts each URL sends — downtime, content changes, slow responses — and we email you when they happen.

What Site Monitor offers

  • Fully hosted and maintained for you
  • 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

Spend your time on the changes, not the infrastructure

Site Monitor is a hosted service: checks, browser rendering, storage, and alerting are run for you. If you need to run monitoring on your own infrastructure, a self-hosted tool may suit you better.

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 open source or self-hostable?

No. Site Monitor is a hosted service.

Is there a free plan?

Yes — 10 URLs checked hourly with 2 AI summaries a month, no credit card required.

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.

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.

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.
