DeadWatch

The gap between check-ins

Sites break between the times you happen to look.

A certificate lapses on a Sunday. A deploy shifts the hero 40 pixels. A third-party script drags LCP to four seconds. A nameserver quietly moves. You find out when someone emails — or worse, when their customers do. DeadWatch stands the watch so the first person who knows about a problem is you.

DeadWatch · Monitor

Vital signs for every site you run.

Not just "is it up." DeadWatch reads the whole health picture, and when a signal drops you hear about it before the phone rings.

◔

Uptime & confirmation

Reachability checks on the site's interval, with a confirmation re-check from a second region. A one-off blip stays quiet; a real outage opens an incident — roughly 30–90s at a 60s interval.

◫

Visual regression

A screenshot of every page against an approved baseline, per breakpoint, with weighted zones. When a deploy shifts the layout or breaks a header, you see the pixel diff before your visitors do.

⚡

Speed & Web Vitals

LCP, FCP, CLS, TBT, TTFB and INP measured in a real headless browser, scored 0–100 with real-user CrUX data where Google has it. Catch the regression before it costs rankings.

◎

SSL, DNS & expiry

Certificate validity and days-to-expiry, full resolver records (A/AAAA/MX/TXT/NS/CNAME/SOA) with a DNS audit, WHOIS domain registration — the quiet failures that take a site down without an error page.

🛡

Security posture

Response-header hardening scored per site — CSP, HSTS, X-Frame-Options and more — plus hijacking, cloaking and spam-injection detection, folded into the health picture as the Security pillar.

◱

Notifications that reach you

Route alerts to Email, Slack, Discord or a generic webhook, per site or per client. Durable delivery through an outbox, flapping guard on, maintenance windows to silence planned work.
