Watch pricing pages, terms and policies, documentation, product pages or competitor sites for content changes. Each run compares the page text with the previous run and returns a clear added / removed lines diff.
$0.0005 per page check. No change fee and no start fee: checking one page every day costs about $0.015 a month. Pages that fail are free, and their stored snapshot is kept.
Quick start: example input, output and cost
Track changes on competitor, pricing and policy pages: clean added/removed text diffs, main-content mode, schedule and alert. $0.50 per 1,000 page checks.
Example input
Cost example: 20 pages checked daily for 30 days = 600 checks x $0.0005 = $0.30/month.
How to use
- Add your URLs and pick a
monitorName. - The first run stores a baseline (
status: "baseline"). - Schedule the actor (hourly, daily...). Every later run returns
status: "changed"or"unchanged"per page. - Alert on changes: Apify integrations (Slack, email, webhook) or filter the dataset on
status = changed.
Fewer false alerts
- Main-content mode ignores navigation, footers, cookie banners and sidebars.
- Ignore patterns strip dates, counters or rotating text before comparing.
minChangedCharssuppresses tiny edits.
Output
url, status (baseline/changed/unchanged), added[], removed[], addedCount, removedCount, changedChars, changeRatio, textHash, previousCheckAt, checkedAt.
Responsible use
We follow robots.txt (RFC 9309), fetch each page once per run at about one request per second per site, use an honest User-Agent (ChangeMonitor/1.0), and never log in or bypass bot protection. Emails and phone numbers are redacted before storing. Social networks and profile sites are not monitored. Pages that need JavaScript to render their text are out of scope.
