Monitor any webpage for changes. Get instant webhook notifications when content updates. Track competitor pricing, product pages, job postings — automatically.
Tell us what page to watch, how often to check, and where to send notifications.
Our engine fetches the page on your schedule, extracts text content, and compares with the previous version.
When content changes, we POST a webhook with the exact diff — what was added, what was removed.
