Everything You Need to Know Your Site Actually Works
Uptime tools tell you the server is on. Sitewatch tells you the page works. We check every asset, validate MIME types, detect redirect loops, grade security headers, and alert you across six channels — with evidence, not guesswork. Here is everything Sitewatch does.
- Full asset and resource verification on every check
- 6 alert channels with retry confirmation and deduplication
- Typed incidents with evidence, fix checklists, and shareable reports
Detection
What Sitewatch monitors on every check
Uptime & ping monitoring
Know the moment your site goes down. 5-minute HTTP pings on all plans detect SITE_DOWN and UNAVAILABLE states. Uptime percentage tracked and displayed on your status page.
Asset validation
Every JS bundle, stylesheet, image, and font on your pages is checked for HTTP status and MIME type. A 404'd script or wrong content type gets flagged immediately.
Security posture monitoring
5 security headers monitored on every check. Regression alerts when a deployment removes a header. Mixed content detection across 9 resource types. No configuration required.
Mixed content detection
HTTP resources on HTTPS pages detected automatically — scripts, images, stylesheets, iframes, and more. Active mixed content flagged critical. Passive content flagged high. Included on all plans.
SSL certificate monitoring
Every SSL certificate monitored continuously — 30-day expiry warning, full chain validation, and TLS protocol and cipher checks. Runs automatically on every check, no configuration required.
Domain expiry monitoring
Domain registration expiry tracked automatically via RDAP for every monitored site. 30-day early warning before a client domain lapses — no WHOIS tools, no manual reminders.
Redirect chain detection
Redirect loops, excessive hop chains, and host drift are caught and reported with full visualization of each hop.
MIME type verification
Assets served with the wrong Content-Type are flagged. Browsers silently block mismatched MIME types — Sitewatch doesn't.
HTML fingerprinting
SHA-256 fingerprints detect unexpected structural changes to your pages. Know when a deploy alters page output you didn't intend to change.
Alerting
Six channels, three layers of noise control
6 alert channels
Slack, email, SMS, webhook, PagerDuty, and Opsgenie — all dispatched independently. If one fails, the others still deliver.
Retry confirmation
2-of-3 retry confirmation before any alert fires. Transient glitches are filtered out. Near-zero false positives by design.
Fingerprint deduplication
SHA-256 fingerprints mean one problem creates one incident — not twenty. A 30-minute cooldown prevents alert storms.
Per-site routing
Override notification settings per site. Different sites can alert to different channels, recipients, or escalation paths.
Reporting
Evidence you can act on and share
Typed incidents
20 detection rules with auto-classified severity, event timelines, and tailored fix checklists. Every incident includes the evidence to diagnose and resolve.
Shareable reports
Generate token-based public links for any incident or bundle of incidents. Share evidence with clients — no login required.
Public status pages
Branded, client-facing status pages with real-time health, quality scores, security grades, uptime history, and announcements.
Quality scores
Overall site quality calculated from availability (25%), redirect health (25%), asset health (25%), and security headers (25%).
