Monitoring.

Website monitoring Watch public pages, checkout flows, and important URLs for downtime, slow responses, and recovery. Keyword monitoring Confirm important text stays present or disappears when a page changes, redirects, or breaks. Ping monitoring Track whether servers and network devices respond before customers notice a reachability issue. Port monitoring Check critical TCP services such as HTTPS, mail, SSH, database gateways, or custom app ports. TCP monitoring Verify that a TCP endpoint accepts connections and alerts when the service stops listening. UDP monitoring Watch UDP-dependent services and network paths where a simple website check is not enough. Cron job monitoring Use heartbeat URLs to prove scheduled jobs, backups, imports, and automations are still running. API monitoring Monitor API endpoints, response codes, JSON assertions, and response time for app-critical services. Email health monitoring Check MX, SPF, DMARC, blacklist, SMTP, and IMAP health without making users configure every detail by hand. Server status monitoring Install Linux, macOS, or Windows agents to report CPU, memory, disk, uptime, and server freshness.

Features.

Multi-location checks Compare signals from more than one location so regional issues do not look like global outages. Response time history Trend response time over time so slowdowns are visible before they become outages. SSL expiry Track certificate dates and warn before a renewal problem takes a secure site offline. Domain expiry Watch domain registration dates and surface renewal risk alongside the rest of the site profile. DNS monitoring Keep A, AAAA, CNAME, MX, TXT, SPF, DMARC, and nameserver records visible and checked. Sitemap intelligence Map submitted URLs and sitemap indexes so site owners can drill into the pages search engines are being handed. SEO readiness checks Audit homepage metadata, headings, canonical tags, structured data, sitemap signals, and customer-ready SEO suggestions. Accessibility checker Surface practical accessibility issues such as missing alt text, unlabeled fields, generic links, heading skips, and landmark gaps.

Incident management Use incident timelines, evidence, notes, acknowledgements, snoozes, and resolution history to keep the story clear.

Fine Print

webmonitor.ninja is provided as an alerting and reporting aid, not as a guarantee that every outage, slowdown, DNS issue, SSL problem, payment interruption, or third-party service failure will be detected, diagnosed, delivered, or resolved.

Monitoring depends on networks, mail providers, SMS gateways, hosting environments, cron schedules, remote services, and configuration choices that may be outside our control. Alerts may be delayed, filtered, blocked, throttled, misrouted, or missed entirely.

By using this service, you agree that you remain responsible for your websites, applications, customers, backups, security decisions, incident response, regulatory obligations, and business continuity planning. Use the dashboard as one signal among many, and verify critical events independently.

The service is offered "as is" and "as available" to the fullest extent permitted by law. No promise is made that it will be uninterrupted, error-free, or fit for a particular purpose. Liability is limited to the amount you paid for the service during the billing period tied to the claim, where such limitation is allowed.
