How it works
Two ways to watch a page.
Public pages are checked from our servers. Pages behind a login are watched from inside your own browser session, so your credentials never leave your machine.
For pages anyone can open.
SiteChime fetches the page on a schedule from our servers and compares it against the previous snapshot. Best for marketing pages, pricing pages, news, blogs, public dashboards, and any URL you can open in an incognito window.
Hourly checks on Pro · 15-minute checks on Pro+
For pages only your browser can see.
Install the Chrome extension, sign in to the page once in your own browser, and SiteChime watches it from inside your session. Internal admin panels, customer portals, supplier dashboards, government tender systems, members-only forums.
We never see your password. Your browser session stays on your machine — only the extracted page text is uploaded.
You don’t need to keep the watched page open. The extension uses your Chrome profile’s existing session and runs each check in a background tab on its own schedule. If a site looks like it needs you to sign in again, SiteChime marks the watch “Sign in required” with an “Open page to sign in” prompt — rather than treating a login screen as a real change.
Available on every plan, including Free.
Add a page
Paste a URL, or pick a section visually with the extension.
We watch it
Cloud mode runs server-side; Browser mode runs in your own browser session.
You hear a chime
Email, Slack, Discord, or any webhook destination.
The alert
Every chime shows you exactly what changed.
Whether you’re tracking a deal or a tender deadline, you get the before, the after, and the difference — in one glance.
What people watch
Built for the pages you keep checking by hand.
Competitor pricing & product pages
Watch a rival’s pricing page, product detail page, or feature matrix. Catch quiet price moves, plan restructures, and silent feature changes before your customers ask about them.
e.g. competitor.com/pricing

Government tenders & procurement
Tender portals rarely email you when a listing, deadline, or status changes. SiteChime watches the page — public RFP boards or logged-in supplier dashboards — and pings you when something moves.
e.g. supplier portal · public tender board

Policy, regulation & compliance
Regulator pages, terms of service, and policy documents update without notice. Watch the section that matters and get the diff in plain English the moment wording changes.
e.g. regulator.gov/policy/2026-08

Behind-login dashboards & portals
Internal admin panels, customer portals, supplier dashboards, members-only forums. Browser mode watches them inside your own signed-in session — your password stays on your machine.
e.g. your Stripe dashboard · supplier portal

Job listings & careers pages
Target employers rarely notify you when a role opens. Watch a careers page or a filtered search and act before the listing buries itself in the feed.
e.g. stripe.com/jobs

Stock, drops & availability
Out-of-stock products, limited drops, waitlist openings. Catch them at the moment they go live, not an hour later when the shelf is empty.
e.g. nike.com/launch

Why SiteChime
What other monitors miss.
Works on pages you’re signed into
Other monitors ask for your passwords so they can log in for you. SiteChime doesn’t. The browser extension watches pages from inside your own signed-in session.
Section-level precision
Visually pick the part of the page you actually care about. SiteChime ignores changes outside that section, so banners, ads, and timestamps don’t trigger alerts.
Plain-English change summaries
Each alert leads with what changed in a single sentence — “Price dropped from $199 to $149”, “Item is back in stock”, “N words were changed in the watched section” — above the raw diff.
Delivery status you can trust
Webhook deliveries show ok, failed, or timed-out in your settings, with the HTTP status and the time of the last attempt. No silent failures.
Failure transparency
When a check fails, the dashboard tells you why — blocked by the site, page structure changed, extension tab couldn’t open — in plain language with what to try next.
Password and session privacy
Browser mode never sees your password. Your browser session stays on your machine; only the extracted page text and the change result are uploaded to SiteChime.
SiteChime never stores your passwords. Browser mode uses your own browser session; only the extracted page text and change result are uploaded.
Picking the right tool
What SiteChime is — and isn’t.
Not an uptime monitor, not a scraping platform. SiteChime watches a specific part of a page and tells you when it changes.
FAQ
Quick answers before you start.
Can SiteChime watch pages I’m signed into?
Yes. Install the Chrome extension, sign in to the page once in your own browser, and SiteChime watches it from inside your session. Internal admin panels, customer portals, supplier dashboards, members-only forums — most pages your browser can see, SiteChime can watch.
Do you store my passwords?
No. Browser mode runs in your own browser, using your own session. Your password never leaves your machine. SiteChime only receives the extracted page text and the change result.
Do I need to keep the watched page open in my browser?
No. The extension uses your Chrome profile’s existing session and opens each check in a short-lived background tab on the schedule you picked. As long as Chrome is running with the extension enabled, you can close the original tab. If the site later looks like it needs you to sign in again, SiteChime marks the watch "Sign in required" with an "Open page to sign in" prompt instead of sending a misleading change alert — so you can re-authenticate in your normal browser and the watch resumes.
What happens if the watched site logs me out?
SiteChime watches for the usual signed-out signals on the next check — a login form where the content used to be, a redirect to a sign-in URL, an authentication-challenge page. When that happens, the watch is marked "Sign in required" with an "Open page to sign in" prompt on the dashboard, instead of sending you a misleading "page changed" alert. Open the site once in your normal browser, sign back in, and the next scheduled check picks up where it left off. Detection is a heuristic, not a guarantee, but the goal is: if SiteChime can’t tell whether the page really changed, you hear "looks like sign-in is needed" rather than a false-positive alert.
What’s the difference between Cloud mode and Browser mode?
Cloud mode checks public pages from our servers on a schedule — best for marketing pages, pricing pages, news, and anything you can open in an incognito window. Browser mode runs the check inside your own browser via the extension — best for pages that need a login. You pick the mode per watch.
How often does SiteChime check a page?
Daily on Free, hourly on Pro, every 15 minutes on Pro+. You can also trigger a manual check at any time from the dashboard.
Is the Free plan actually useful, or just a teaser?
Free includes 5 watches and daily checks, with email alerts. It’s enough to genuinely monitor a few pages you care about — most people start there and only upgrade once they hit the watch limit or want faster checks.
