Install the SiteChime extension

Use Browser mode to monitor pages only your browser can see.

Cloud watches run from SiteChime’s servers. Browser watches run from your own browser, so they can monitor logged-in pages without storing your credentials.

Works with Chrome, Brave, Edge, ArcChromium-based browsers
SiteChime product illustration — the bell mark, the tagline 'Website changes, caught in time.', a stylised dashboard preview, and four feature highlights: monitor any page, works in your own browser, get alerts when changes happen, and your data your privacy.

Why Browser mode?

Cloud mode covers public pages. Browser mode covers everything else — anything tied to your own session.

Logged-in pages, watched

Dashboards, account portals, paywalled articles, internal tools.

Credentials stay local

No passwords, cookies, or 2FA codes leave your browser. Ever.

Your real session

Pages render exactly as you see them — including A/B tests and personalisation.

Your passwords stay in your browser

SiteChime monitors what your browser can see — we never store your credentials, session cookies, or two-factor codes. The extension reads page content from your active session and uploads only the cleaned text snapshot.

Cloud or Browser mode?

Both run alongside each other. Pick the right mode per watch when you add it.

No extension needed

Chrome Web Store install

Coming soon

The easiest way to install SiteChime will be from the Chrome Web Store. Once the listing is approved, you’ll install in one click and get automatic updates.

Download ZIP manually

Manual install for testing

Until the Chrome Web Store listing is live, you can install SiteChime manually. Same extension, just a few extra steps.

  1. 1

    Download the extension ZIP

  2. 2

    Unzip the file

    Right-click the ZIP and choose Extract All. Remember where the unzipped folder lives.
  3. 3

    Open your extensions page

    In Chrome, Brave, Edge, or Arc visit chrome://extensions.
  4. 4

    Enable Developer mode

    Toggle Developer mode on (top-right of the extensions page), then click Load unpacked and select the unzipped folder.
  5. 5

    Sign in and start a Browser watch

    Open your dashboard in the same browser profile, then add a watch in Browser mode.

A few things to know before installing

  • Only install SiteChime from sitechime.com. If you see this extension hosted anywhere else, it is not us.
  • Your passwords stay in your browser. SiteChime monitors only the page sections you explicitly choose with the visual picker. We never see your login credentials. Read our privacy policy.
  • 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 on its schedule. If a watched 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.
  • This beta build may change while Chrome Web Store review is pending. Until the store listing is approved, testers may need to re-download the latest build from this page.
  • Chrome may show a “disable developer mode extensions” warning while using the beta install. This is normal for side-loaded extensions and should disappear once SiteChime is installed from the Chrome Web Store.
