Build on the MonSPHERE platform
Real, technically accurate guides covering everything from your first monitor to platform administration — reflecting the actual API, not marketing copy.
Getting Started
Installation
Monitoring
Website Monitoring
HTTP/HTTPS, TCP, DNS, SSL, and ping checks — with regex assertions, custom headers, TLS, and multi-region probing.
Cron Job Monitoring
Your cron job or scheduled task pings us on its own schedule — we alert the moment a run goes missing.
Synthetic Monitoring
Scripted multi-step browser checks — navigate, click, fill, wait, and assert — for real user-journey monitoring beyond a simple uptime check.
API Transaction Monitoring
Chain multiple HTTP requests into one scripted transaction — extract a value from one response and reuse it in a later request.
DNS Blacklist Monitoring
Check whether an IP is listed on spam blacklists (RBL/DNSBL) — catch a reputation problem before it blocks your mail delivery.
WHOIS Monitoring
Track a domain's own registration expiry and catch an unexpected ownership transfer — with a real WHOIS lookup, not a certificate check.
Certificate Transparency Log Monitoring
Get notified the moment a new certificate is issued for your domain or a subdomain — catches unauthorized issuance and shadow IT early.
Port Discovery
Full-range TCP port scan of a host you own to flag any port that's open now but wasn't before — an early warning for an accidentally-exposed service.
Core Web Vitals Monitoring
Load your page in a real browser on a schedule and track LCP, CLS, FCP, TTFB and TBT over time — get alerted when LCP or CLS cross Google's thresholds.
Lighthouse Monitoring
Scheduled Lighthouse audits — Performance, Accessibility, Best Practices and SEO scores tracked over time, with an alert when a score drops below your minimum.
Accessibility (WCAG) Monitoring
Scheduled axe-core audits of your page against WCAG 2.x A/AA in a real browser — violated rules by impact and affected elements, with an alert when critical issues appear.
Typosquatting Monitoring
Find registered lookalikes of your domain — typos, homoglyphs, IDN homographs, other TLDs, "brand-login" names — and get alerted when a new one appears.
Sitemap & URL Monitoring
Watch a sitemap for added and removed URLs and check that every listed URL still answers — alerting when a URL breaks.
Broken Link Monitoring
Crawl your site and find broken internal and external links, images, scripts and stylesheets — with the pages that link to them.
Subdomain Monitoring
Find every subdomain of your domain in Certificate Transparency logs, check each one in DNS, and get alerted on new subdomains and dangling CNAMEs.
Screenshot Monitoring
Scheduled visual snapshots of a page, diffed pixel-by-pixel against the previous one to catch a change nothing else picks up on.
Cookie Monitoring
Track a page's cookies for unexpected additions, removals, or security-attribute changes — Secure, HttpOnly, and SameSite, not just whether a cookie is still there.
Content Change Monitoring
Alert when a page's visible text or detected technology stack changes — a plain HTTP fetch, not a headless browser.
robots.txt & Meta Noindex Monitoring
Alert the moment a page or an entire site is accidentally deindexed — a one-line config mistake that otherwise goes unnoticed for weeks.
Email Authentication (SPF/DKIM/DMARC) Monitoring
Watch a domain's email authentication records for the silent misconfiguration that tanks deliverability.
Infrastructure Monitoring
Server, container, database, and cloud infrastructure metrics via agents and exporters.
Alerting & Incidents
Dashboards & Reporting
API & Auth
Administration
Organizations & Multi-Tenant
How isolation, membership, and cross-organization access actually work.
Licensing & Subscriptions
Plans, real enforced limits, and cloud / enterprise / offline license types.
Platform Administration
The cross-organization console: organizations, licenses, feature flags, and audit.
