Website Status Checker
Check if a website is up or down, inspect the redirect chain, review security headers, and look up DNS records.
How to Use This Tool
- Enter a URL — type any website address (e.g., example.com or https://example.com/page).
- Click Check — the tool tests the connection, follows redirects, checks headers, and looks up DNS records.
- Review the report — see whether the site is up, how fast it responds, and whether security headers are configured.
- Explore tabs — switch between Overview, Headers, and DNS Records for detailed information.
What This Tool Checks
HTTP Status
Whether the site responds, the status code, and response time.
Redirect Chain
Every redirect hop from the original URL to the final destination.
Security Headers
HSTS, X-Frame-Options, CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy.
Server Info
Server software, HTTPS status, response headers.
DNS Records
A, AAAA, CNAME, MX, NS, and TXT records via Cloudflare DoH.
Session History
Keeps track of every URL you check during this session.
Common Use Cases
- Down detector — quickly check if a website is down for everyone or just you.
- Redirect auditing — verify your 301/302 redirects are working and not creating chains.
- Security review — check whether a site has basic security headers configured.
- DNS debugging — verify A records, MX records, and nameservers without terminal access.
- Migration checks — after a domain or hosting migration, verify DNS, redirects, and HTTPS.
Understanding Security Headers
Security headers tell browsers how to behave when loading your site. Missing headers can leave your site vulnerable:
- HSTS — forces HTTPS connections, preventing downgrade attacks.
- X-Frame-Options — prevents your site from being embedded in iframes (clickjacking protection).
- CSP — controls which scripts and resources can load on your page.
- X-Content-Type-Options — prevents MIME type sniffing.
- Referrer-Policy — controls how much referrer info is shared with other sites.
- Permissions-Policy — restricts which browser features (camera, mic, geolocation) your site can use.
Frequently Asked Questions
Is this the same as ping?▾
Not exactly. This tool makes an HTTP request (like a browser would), not an ICMP ping. It checks whether the website serves a response, not just whether the server is reachable at the network level. This is more useful for checking if a website is actually working.
Why does it show redirects?▾
Many websites redirect from HTTP to HTTPS, from www to non-www, or from old URLs to new ones. Seeing the full redirect chain helps you verify your redirects work correctly and aren't creating unnecessary hops that slow down page loads.
Where does the DNS data come from?▾
DNS lookups use Cloudflare's public DNS-over-HTTPS service (1.1.1.1). This is a reliable, privacy-focused resolver, but results may differ slightly from your local ISP's DNS.
Does this tool store any data?▾
No. The URL is sent to our server only to make the HTTP request and DNS lookup (browsers can't do this directly due to CORS). Nothing is stored. Session history is kept in your browser only and cleared when you leave the page.
Why might a site show as down?▾
The site may actually be down, or it may block automated requests (WAF/firewall), require authentication, or have DNS issues. Some CDNs and security services (Cloudflare, Akamai) may challenge our request differently than a browser.
What's a good response time?▾
Under 500ms is fast, 500–2000ms is acceptable, over 2000ms is slow. Note that this measures server response time from our edge server, not from your location — your actual experience may differ.
