Email alerts when a page changes — without you refreshing it.
SiteChime is a website change monitor and webpage change detector. Pick any URL, draw a box around the section that matters, and get a plain-English email when the next check sees that section change — or route it to Slack, Discord, or a webhook.
The problem
Most pages don’t notify you when their important parts move.
Pricing pages get re-released without an email. Terms of service quietly grow new clauses. Vendor status pages update before the incident posts. Government policy pages drop new PDFs. A competitor’s blog publishes the announcement you’ve been waiting for.
SiteChime turns every URL into a watched page. Pick the exact section you care about, set how often you want it checked, and get a clear alert with the diff on the next check after it moves. No browser extension needed for public pages.
How it works
Public pages and pages behind a login, both covered.
Cloud mode — for public pages.
Paste any public URL. SiteChime fetches it from our servers on a schedule and compares each snapshot to the previous one. No install, no setup. Works on pricing pages, blogs, news, docs, status pages, government pages, anything public.
Hourly checks on Pro · 15-minute checks on Pro+
Browser mode — for pages behind a login.
Install the Chrome extension and sign in to the page once in your own browser. SiteChime watches the page from inside your session, so it sees what you see. Your password never leaves your machine.
Your password never leaves your machine. Only the extracted page text is uploaded. Get the extension.
What gets monitored
The pages people most often want change alerts on.
Pricing & plan pages
Watch a vendor’s pricing page and hear when the next check sees a plan change price, a tier renamed, or a new feature appear in the feature matrix.
Terms of service & privacy policies
ToS and privacy pages quietly grow new clauses. Watch the document body and get a diff on the next check after a clause is added, removed, or rewritten.
Competitor blog & news pages
Watch a competitor’s blog index or release-notes page and get pinged when SiteChime sees a new post — often before the RSS aggregators pick it up.
Documentation & API reference
Watch the changelog page of a doc site, an API reference endpoint, or a deprecation notice. Catch breaking changes before they break your build.
Vendor status pages
Watch a vendor’s status page and hear about the incident before the email goes out. Common for AWS, Stripe, Twilio, GitHub, Cloudflare, OpenAI.
Government & policy pages
Regulators and councils post updates on slow, ugly pages with no RSS. Watch the announcements section and get a diff on the next check after something is posted.

Why SiteChime
Built for people who just want a clear email when a page moves.
Section-level precision
The visual section picker lets you watch just the part of the page that matters. Header redesigns, sidebar changes, and footer updates don’t fire false alerts.
Plain-English summary
Each alert leads with what changed in one sentence — "Price changed", "New plan added", "Status changed to Investigating" — above the raw diff. Skim-friendly.
Email, Slack, Discord, webhook
Route alerts to email, Slack, Discord, or any webhook destination on Pro and above. Personal channels, team channels, or pipe to your own automation.
Works on pages behind a login
Browser mode watches logged-in pages from inside your own browser session. Patient portals, internal tools, supplier portals, dashboards — your password never leaves your machine.
No noise from cosmetic edits
SiteChime ignores whitespace-only changes, cosmetic reflows, and trivial timestamps. You hear about real content changes, not the page’s "last updated" footer ticking over.
Failure transparency
When a check fails — the site blocked us, the page structure changed, a Cloudflare challenge appeared — the dashboard tells you why in plain language so you can fix it.
FAQ
Common questions about page change alerts.
How is this different from a generic "website change monitor"?
Two things. First, section-level precision — you draw a box around just the part of the page that matters, so cosmetic edits to the rest of the page don’t fire false alerts. Second, browser mode — you can watch pages behind a login from inside your own browser session, without giving SiteChime your password.
Can SiteChime watch a page behind a login?
Yes — install the Chrome extension, sign in to the page once in your own browser, and SiteChime watches the page from inside your session. Your credentials stay on your machine. Only the extracted text from the section you picked is uploaded. You don’t need to keep the watched tab open: the extension uses your Chrome profile’s existing session and opens each check in a short-lived background tab. If the site later looks like it needs you to sign in again, SiteChime marks the watch "Sign in required" with a "Sign in to resume" prompt instead of treating a login screen as a real page change.
How fast will I get an alert?
Cloud-mode checks run as often as every 15 minutes on Pro+, hourly on Pro, daily on Free. Browser-mode checks run on a schedule from your own browser; you can also trigger a manual check at any time. We don’t promise instant alerts — honestly, "within your plan’s check interval".
Does SiteChime scrape protected data or bypass paywalls?
No. We watch the page exactly as you see it. For public pages, cloud mode fetches what your browser would fetch. For logged-in pages, browser mode runs inside your own already-signed-in session. We don’t bypass paywalls, defeat anti-bot challenges, or scrape protected fields.
What about email delivery — will alerts hit my inbox?
Alerts go via Resend with SPF/DKIM aligned to our domain, so they land in the inbox for almost every mail provider. If you’re on Pro and want a more durable channel, route to Slack, Discord, or a webhook — those bypass spam-folder questions entirely.
How does pricing work?
Free includes 5 watches with daily checks. Pro is $9/month for 25 watches with hourly checks plus Slack, Discord, and webhook destinations. Pro+ is $19/month for 50 watches with 15-minute checks and a priority queue.
