About Visual Sentinel

What is Visual Sentinel?

Visual Sentinel is a website monitoring tool that checks more than basic uptime. It monitors six layers of website health: uptime, performance, SSL, DNS, visual changes, and content changes. The site positions itself around a common gap in traditional monitoring: a page can return HTTP 200 OK while still being broken for visitors because of layout issues, slow performance, expired certificates, DNS changes, or altered page content. Visual Sentinel addresses this by running external checks, capturing screenshots, comparing visual differences, tracking text and markup changes, and sending alerts with supporting evidence. Alerts can be sent through channels such as email, Slack, Discord, WhatsApp, Telegram, and webhooks. The product is built for teams that need fast, actionable notice when customer-facing pages change or fail, without requiring code changes, agents, or browser extensions.
