When to Use This Checker
Use this tool when a site won’t load in your browser, when you’re debugging your own or a client’s site, or when you need to confirm whether a domain is registered and responding. Because the check runs from our server, you get an objective result: if we can reach the site and get an HTTP response, we show you the status code and timing. If the domain doesn’t resolve or the connection fails, we show an error. That helps you tell the difference between “the site is down” and “my network or browser has a problem.”
Website owners often run a quick check after changing DNS or moving hosting to confirm the new setup is live. Developers use it to verify that a staging or production URL is reachable before sharing it. Support teams use it to confirm a customer’s site is up when the customer reports issues. There’s no sign-up and we don’t store the URLs you check; see our Privacy Policy for details.

Quick reference for result codes. Full guide.
| Code | Meaning |
|---|---|
| 200 | OK - site responded successfully |
| 301 / 302 | Redirect - permanent or temporary |
| 404 | Not Found - page or resource doesn't exist |

| 429 | Too Many Requests - rate limited |
| 500 / 502 / 503 | Server error - site or backend problem |
About Website Availability Checking
This tool is for website owners, developers, and support teams who need a quick way to see whether a site or domain is reachable, whether DNS is set up, and how the server responds (status code, timing, SSL).
Why use it?
- Domain Status Verification: Check if a domain is registered and has DNS records configured
- Monitor Uptime: Ensure your website is accessible to users at all times
- DNS Troubleshooting: Verify DNS resolution and identify DNS configuration issues
- Debug Issues: Quickly identify if a website is down or experiencing problems
- Performance Analysis: Measure response times and identify slow-loading websites
- SSL Verification: Check if websites are using secure HTTPS connections
- Status Code Analysis: Understand HTTP response codes to diagnose issues
What you get
Each check can include:
- Domain & DNS: Whether the domain resolves and has records
- HTTP code: 200, 404, 500, etc., plus redirect chain and final URL
- Timing: Response time and total time (ms)
- SSL/HTTPS: Secure connection and certificate
- Content: Type, size, page title, meta description, favicon when available

FAQ
How does the checker work?
When you submit a URL, we normalize it, validate the domain, check DNS resolution, then attempt an HTTP(S) request and report the HTTP status code, timing, redirects, and basic page metadata when available.
Is this an uptime monitor?
No. This tool is designed for quick, on-demand checks. For monitoring uptime over time, use a dedicated uptime monitoring service.
Why do some websites show “Online but Limited”?
Some sites block automated requests (rate limiting, bot protection, or Cloudflare challenges). In that case we can often confirm the site is reachable, but may not be able to fetch full page content.
What URLs are not allowed?
For security reasons, we block checks to local/private networks (e.g., localhost, 127.0.0.1, 192.168.x.x) to prevent abuse.
Do you store the URLs I check?
We do not intentionally store the URLs you submit in a database. Standard server logs may record basic request information (as most web servers do). See our Privacy Policy for details.
What do the results mean?
Online means the site responded successfully (usually HTTP 200). Offline or Error means the request failed (e.g. DNS issue, connection refused, or timeout). Online but Limited means we could reach the server but some content or metadata was blocked (e.g. by bot protection). The HTTP status code (200, 404, 500, etc.) and response time give more detail for troubleshooting.
