What is Visual Sentinel?
Visual Sentinel is a website monitoring tool that tracks when your site experiences problems, breaks, or performance issues. It focuses on visual monitoring, meaning it watches how your website actually appears and functions in a browser rather than just checking if servers are up. The tool automatically alerts you when visual elements fail to load, pages break unexpectedly, or user-facing functionality stops working. It's designed for teams who need to catch problems quickly before users report them. Visual Sentinel is free to use, making it accessible for small businesses, freelancers, and teams testing their monitoring needs without upfront cost.
