In their own words
DomainWarn
DomainWarn monitors client domains for changes to websites, DNS, MX, SPF and DMARC, and brings checks and alerts into one dashboard. Its domain check runs 21 checks across website, email, DNS and registration, with area scores and an overall score. It detects record and name-server changes, checks them against a second name server, and displays old and new values. Related issues can be grouped into incidents, with reminders and one all-clear message after recovery.
The service supports 20 notification channel types, including email, Slack, Microsoft Teams, Discord and SMS. DNS integrations include Cloudflare, Hetzner DNS, IONOS, netcup, INWX and Amazon Route 53. It is available on the web, via API, and through WordPress, Shopware and Chrome extensions. The free plan is free with three domains, two members and seven days of history. Freelancer is €19 a month; Agency is €49 a month; Agency Pro is €99 a month. The service is offered to businesses, not consumers.
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.
