Visual Sentinel
Visual Sentinel monitors websites and servers, including page changes that ordinary uptime checks may miss. Its monitoring covers uptime, screenshot-based visual comparison, SSL, DNS, performance, content, APIs, endpoints, and servers. For visual checks, it captures a page in a browser and compares the screenshot with a prior baseline. Users can exclude changing page elements with CSS selectors and set the amount of change needed to flag a capture. Failed uptime checks are repeated; a site is marked down only if it fails from all selected regions. Alerts can go to email, Slack, Discord, WhatsApp, Telegram, Microsoft Teams, PagerDuty, OpsGenie, webhooks, Prometheus, and browser push. The REST API manages monitors, incidents, status pages, maintenance windows, reports, and notification channels; API access is listed for Business and Agency. The Free plan costs nothing and includes three monitors, 10-minute checks, and one status page. Solo costs $6 a month. Visual Sentinel is built and operated by Acefina LLC and is intended for small teams, agencies, and site owners.
