Fluxguard vs PageScreen

Fluxguard monitors web pages and related data for changes, with detection that covers visual appearance, text, rendered DOM and HTML, and network activity. Its headless Google Chrome crawler can render assets loaded by JavaScript. Users can narrow or exclude page areas with CSS selectors, network blocks, DOM attribute rules, and keyword lists. The product is intended for tasks such as tracking regulations, watching competitors, and protecting a customer’s own assets. Slack alerts can be routed to selected site categories, while webhooks send change data to a chosen endpoint. Fluxguard also offers an API, which its documentation marks as beta. The service is available on web and through an API, with a free plan and a 7-day trial. Free includes 3 sites per month, one user, and three versions per page; paid plans range from $110.00 to $550 a month. It preserves a plan-specific number of page versions, removing the oldest when the limit is reached, and does not support extremely rapid third-party crawling.
