Portland, Oregon, United States
What it is
Fluxguard is a website change intelligence platform for monitoring web-based data and responding when it changes. Its use cases include tracking regulations, monitoring competitors, and protecting a customer's own assets. It detects visual, text, rendered DOM and HTML, and network activity changes. Fluxguard uses headless Google Chrome to render pages, including assets loaded by JavaScript. Users can focus or exclude page areas with CSS selectors, network blocks, ignored DOM attributes, and keyword lists. The service provides webhooks for sending change data to a chosen endpoint; its API documentation identifies the API as beta. Site categories can route alerts to selected groups of sites in Slack and webhooks. The free plan is described as suitable for an individual monitoring a few pages, while paid plans are presented for individuals and teams. Each plan retains a limited number of page versions and removes the oldest when that limit is exceeded. Fluxguard says it does not support extremely rapid third-party crawling, such as tracking festival tickets, apartment availability, or equity trading. All plans include automated chatbot help, and an account manager is available for account-related assistance. Fluxguard says its team developed the product in 2018 and that it has been part of LegitScript since 2023.
