Competitors change pricing quietly. A tier gets $20 more expensive, an annual discount disappears, an "Enterprise: contact us" row appears. There's no press release, no email. By the time you notice, your sales team has spent weeks selling against a page that no longer exists.
Pricing pages churn constantly without meaning it: rotating testimonials, cookie banners, A/B tested headlines, currency toggles. Pixel-diff monitors alert on all of it, and after the fifth false alarm nobody opens the alerts. The thing you actually want is judgment: did a number that matters move?
Hawkline reads the page text before and after, writes two sentences about what actually changed, and deliberately sends nothing when the change is cosmetic. Silence is the feature that keeps the alerts readable.
Hawkline checks on a schedule (15-minute minimum on paid plans), reads text rather than pixels, and links the source in every alert so you can verify before acting. Some sites block all automated readers; those fail visibly on your desk, never silently.
