Uptime & confirmation
Reachability checks on the site's own interval, with a confirmation re-check before anything pages you. 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 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 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 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 — so the signal reaches you and the noise doesn't.
