DNS. Security. Performance. Email Deliverability. Subdomains. All in one place.
Proactive domain monitoring that catches subdomain takeovers, email delivery failures, and performance issues before they become client emergencies. Not just alerts — intelligence.

The more domains you manage, the harder it gets to stay ahead of problems. You need visibility before issues become emergencies.
Subdomains multiply fast. Orphaned CNAME records become takeover vulnerabilities. You can't secure what you can't see.
SPF, DKIM, DMARC look fine on paper — but are your emails actually reaching inboxes? Passive monitoring can't tell you.
Lighthouse scores drift. SSL certificates expire. Sites slow down. Without regular monitoring, you only notice when clients complain.
Built for developers and agencies managing real infrastructure, not just checking boxes.
Automated Lighthouse audits across key pages. Monitor trends and get alerted when metrics degrade.
Track certificate expiration, monitor HTTP security headers, and validate your security posture continuously.
Monitor A, AAAA, CNAME, MX, TXT, NS, SOA and more. See exactly when records changed and what they changed from.
Certificate transparency monitoring and scanning detects dangling records and takeover vulnerabilities.
Send test emails and verify actual delivery. Track deliverability trends and catch issues before they impact clients.
Validate email security setup and get alerts when configurations break or policies change.
Send alerts via email, Slack, Discord, or webhooks. Configure what changes matter per domain, with fine-grained control over record types and severity.
Monitor registration details and get alerted before domains expire or ownership changes — critical for agencies managing client portfolios.
Leave notes on DNS changes, certificates, alerts, performance results, and more. Pin important context, @mention teammates to loop them in, and build a shared record of what happened and why.
No complex setup. No agents to install. Just add your domains and start monitoring.
Import a list or add individually. Subdomain discovery begins automatically. We find pages to monitor across each domain.
DNS, email security, SSL, performance, and security vulnerabilities scanned. Subdomains discovered via certificate transparency logs.
Get notified via email or webhooks. Customize what changes matter. View trends and collaborate with your team.

A 99.9% uptime badge looks like proof nothing went wrong. It’s proof of something much narrower: that a server answered a request quickly enough, often enough. Whether the page it returned actually worked for the person waiting on it is a different question, and most uptime monitoring never asks it. What uptime monitoring actually measures […]

A 100 on Lighthouse’s accessibility audit feels like a finished checklist. It’s closer to a first pass. The audit is automated, and automated testing can only catch what’s mechanically detectable, which is a smaller slice of real accessibility than the clean round number suggests. What Lighthouse’s accessibility score actually checks Lighthouse’s accessibility category runs on […]

Every page a browser loads can, by default, be asked to hand a visitor’s camera, microphone, or location to any script running on it, including scripts your site didn’t write and doesn’t control. Almost nobody explicitly closes that door. What Permissions-Policy actually controls Permissions-Policy is a response header that declares which browser features and APIs […]
