Everything you need to know about WatchtowerData.
You can monitor any publicly accessible webpage — pricing pages, feature pages, blog posts, landing pages, documentation, and more. WatchtowerData handles both static HTML and JavaScript-rendered (SPA) pages.
WatchtowerData automatically strips cookie banners, chat widgets, timestamps, session tokens, random counters, and other dynamic elements. You can also add custom CSS selectors to ignore specific page elements. This means you only get alerted about meaningful content changes.
Instant alerts notify you the moment a change is detected (subject to cooldown settings). Daily and weekly digests group all changes into a single summary email sent at your preferred time. You can mix and match — instant alerts for pricing pages, weekly digests for blog posts.
Absolutely. You can set per-page cooldown periods (e.g., no more than one alert per hour), quiet hours, max emails per day, and a grouping window. WatchtowerData is designed to be not annoying.
You get a clean before/after text comparison with added content highlighted in green and removed content in red. There's also a summary of what type of change occurred (pricing, heading, links, etc.) along with a severity score.
Yes! WatchtowerData has built-in pricing change detection. When prices on a page change, the change is automatically categorized as a 'pricing' change with high severity, and you can set up instant alerts for those.
Yes, every plan includes a 7-day free trial. A credit card is required to start, but you won't be charged until the trial ends. Cancel anytime before day 8 and you'll never pay a thing.
Currently WatchtowerData supports individual accounts. Team features (shared competitors, multi-user workspaces) are on our roadmap. In the meantime, you can forward digest emails to your team.
WatchtowerData tracks errors and uses exponential backoff for retries. You'll see the error state in your dashboard but won't receive false-positive change alerts. After several consecutive failures, the page enters a degraded state visible in the UI.
Change history and snapshots are available via the dashboard. An API for data export is on our roadmap.
