The quiet stuff that takes sites down. Watched.
Domain expiry, DNS hygiene, nameserver health, and TLS certificates — monitored continuously, with alerts long before anything bites.
Four steps. One pasted URL away.
- 01
Scan your domain
Registration, nameservers, DNS records, and the full TLS chain are inspected in one pass.
- 02
Expiry dates tracked
Domain and certificate expirations sit on a countdown — no more surprise renewals.
- 03
TLS graded
Protocol versions, cipher suites, and chain validity roll up into a single letter grade.
- 04
Alerts before it bites
Expiring certs, lapsing domains, and DNS drift trigger email alerts with time to act.
Built by people who shipped vibe-coded apps and broke them.
Expiry watchtower
Domains and certificates ranked by time-to-expiry across every project you monitor.
DNS & nameserver health
Resolution consistency, nameserver redundancy, and record hygiene checked on every scan.
TLS grade you can show
A clean A on your TLS setup, backed by the cipher-level detail when someone asks.
DNSSEC & drift detection
Missing DNSSEC and unexpected record changes surface as findings, not surprises.
Watch your domain. Free until you find something.

Paste any URL — production app, staging build, vibe-coded prototype.
One scan grades both halves of being found in 2026: classic search (SEO — 68 checks on indexability, metadata, structured data, content, and Core Web Vitals) and AI answer engines (AEO — 46 checks on whether ChatGPT, Claude, Perplexity, and Google AI can crawl, parse, and cite your site).
Every CheckVibe finding ships with a copy-paste prompt engineered for Claude, Cursor, and Windsurf — context, file paths, the exact diff.
Watch the traffic hitting your live app, classify suspicious patterns, and surface real threats — credential stuffing, scraping, prompt-injection probes — without flooding your inbox with noise.
Set a project up once.
Branded, executive-style PDFs and shareable dashboards for stakeholders, clients, and security reviewers — without writing a single sentence yourself.
Plug CheckVibe into Claude Desktop, Cursor, or any MCP-compatible client.
Synthetic lab runs and real-user CrUX data, side by side for every vital.
Cookie consent, privacy policy, terms, and GDPR signals — audited on your live site, tracked over time, and explained in plain language.
Automated WCAG 2.
SPF, DKIM, and DMARC graded in one pass — plus continuous DMARC report monitoring and blocklist checks, so deliverability problems surface before your users stop hearing from you.
