Fluxguard

What Fluxguard is

Fluxguard monitors web-based information and alerts users when sites change. It is designed for use cases such as tracking regulations, monitoring competitors, and protecting a company’s own assets. Its detection covers visual appearance, text, rendered DOM and HTML, and network activity. A headless Google Chrome crawler renders pages and JavaScript-loaded assets. Users can narrow or exclude monitored areas with CSS selectors, network blocks, ignored DOM attributes, and keyword lists. Alerts can be routed to selected site groups through Slack or webhooks, which send change data to a chosen endpoint. Fluxguard also offers an API, though its documentation labels it beta. The free plan allows 3 sites per month, 1 user, and 3 versions per page; it includes visual, HTML, and text detection with instant or daily alerts. Paid plans are presented for individuals and teams, and a 7-day trial is listed. Version retention varies by plan, with the oldest version removed when its limit is exceeded. Fluxguard says its team developed the product in 2018 and that it has been part of LegitScript since 2023.
