Fluxguard vs OnWebChange

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.

OnWebChange monitors webpages and sends alerts when it detects changes. Users can track particular page elements, including prices, headlines and listings, and monitor content on sites that load dynamically with JavaScript. It also checks PDFs, images, text files and other online documents, and can reach login-protected pages using custom headers. Notifications are available by email, mobile notification and webhook; Pushover is named as a third-party mobile notification service for Android and iOS. Checks can run as often as every five minutes. The service can translate tracked content and summarize updates, while groups, labels, pause and resume controls, and CSV import and export help manage trackers. Access is listed for Android, iOS, web and API. The Free plan is free and includes three page trackers with basic daily monitoring. Lite is €0.89 a month, and Standard is €2.79 a month with unlimited trackers. Documentation, video tutorials, email and member support enquiries are available.
