## About

Visual Sentinel monitors websites like a visitor, not just a ping. It combines uptime, performance, SSL, DNS, content, and pixel-level visual checks in one dashboard, then sends evidence-rich alerts through email, Slack, Discord, WhatsApp, Telegram, webhooks, and more. Agencies and product teams use it to catch broken layouts, checkout regressions, defacement, certificate or DNS changes, slow pages, and silent content changes while a site still returns 200 OK. It includes public status pages, client reporting, server-to-site correlation, Android alerts, a REST API, webhooks, and an MCP server for agent workflows. The permanent Free plan includes three monitors; paid plans start at $6/month.

## Pricing

Free forever: 3 monitors. Optional 7-day no-card Business trial. Paid plans from $6/month.
