Find out if a website is safe, set up correctly, and working well — one free report covering security, email, speed, and more.
Not sure if a website is safe to visit or ready to launch? Enter any website address and we'll run a structured health check — the same kinds of tests an IT consultant would run — and explain the results in plain English.
You'll learn whether the secure connection is valid, email is configured properly, the site loads at a reasonable speed, and other essentials that affect trust and reliability. Useful for business owners, bloggers, and anyone evaluating a domain before purchase or launch.
Run a quick check before go-live, after a migration, or as a routine checkup. For a deeper look, switch to a full check to include network routing and open-port tests. Read our domain health guide →
11 checks · about 5 sec
Ready when you are — enter a website address above to see if it's safe and set up correctly.
Enter any domain in the box above and run a quick check. You get a plain-English report covering SSL, DNS, email setup, security headers, and page speed — usually in about 5 seconds. No account needed.
Quick check runs 11 tests: HTTPS certificate, DNS records, email authentication (SPF/DKIM/DMARC), security headers, robots.txt, ads.txt, page speed, and more. Full check adds network routing and open-port tests.
Yes. No signup, no credit card, no usage limits beyond a fair rate limit (20 checks per minute). Results are generated in real time and not stored on our servers.
Yes. After a check completes, use the share button to copy a link with the domain pre-filled — useful when sending results to a client or colleague.
Unlike a single-purpose tool, the Website Health Check runs a coordinated audit across multiple layers of your site: HTTPS certificate validity, DNS configuration, email authentication (SPF, DKIM, DMARC), security response headers, robots.txt presence, ads.txt if applicable, and page load performance. A full check adds network routing and open-port visibility for deeper infrastructure review.
Each finding is explained in plain English — not just raw technical output — so business owners, freelancers, and IT teams can act on the report without decoding jargon first. We built this because real outages rarely sit in one silo: DNS can look fine while MX is broken; SSL can be valid while HSTS is missing; the homepage can load while email is silently failing SPF.
Every module returns evidence from a live probe — not a scraped third-party scoreboard. Severity is assigned by impact on visitors or mail flow:
We deliberately avoid a single vanity “score out of 100” that hides what broke. A brochure site and a payment portal have different risk profiles; the report lists what failed, why it matters for your use case, and what to change. For the full grading rationale, read How We Grade Website Health.
The report opens with an overall assessment and priority issues ranked by severity. Priority issues affect security, email deliverability, or availability now. Other findings are improvements worth scheduling but not emergencies. The action checklist at the end summarizes concrete next steps you can assign to a developer or handle yourself if you manage DNS.
Technical evidence is available for each module if you need to share raw data with a hosting provider or registrar. Re-run after changes — DNS TTL and CDN cache mean the public view can lag your edits by minutes to hours. See How to Read a Website Health Report for a section-by-section walkthrough.
A small business moved from shared hosting to Cloudflare. Their site loaded fine in a browser, but email stopped working. A health check revealed the MX records still pointed to the old host while A records already pointed to Cloudflare. Fixing MX in the DNS panel restored mail within an hour — something a single SSL check would never have caught. Similar “split brain” failures show up after registrar transfers and after agencies flip only the web records.

Quick covers the layers most site owners need day to day: TLS, DNS, email auth signals, security headers, robots/ads.txt, and basic performance. Full adds traceroute-style path insight and common-port visibility from our infrastructure — useful when you suspect firewall or routing issues, not when you only need to know if HTTPS and MX are sane.
Results reflect a point-in-time snapshot from our servers. Some checks depend on public DNS and remote endpoints responding normally. We do not store your domain or results. Port and traceroute checks in full mode only scan common ports from our infrastructure — not a substitute for authenticated penetration testing. Always verify critical changes with your hosting provider and re-check after TTL expiry.
