    FAQ

    What can Watchtower monitor?

    Any public web page: competitor pricing pages, terms of service, privacy policies, changelogs, careers pages and docs.

    How will alerts work?

    When a watched page changes meaningfully, you get a readable diff by email or Slack, plus a weekly digest of everything that changed.

    Is it live?

    Watchtower is in early access. Join the waitlist and we’ll email you when it opens. Pricing shown is planned, and billing is not live.

    How is this different from a screenshot diff?

    We extract the text and structure of the page, so you see “Starter: $19 → $25” instead of a page of red pixels, and noise like rotating banners is ignored.
