HTTP Status Checker – Instantly Find Out If Your URLs Are Working Right

Illustration showing multiple website URLs with color-coded HTTP status codes (200 OK, 404 Not Found, 301 Redirect), a browser window, and arrows indicating server responses—visualizing a bulk HTTP status checker process.

Let’s be real—nobody likes broken links. If you’re managing a website, checking your HTTP status regularly is just smart maintenance. That’s exactly what this free HTTP Status Checker does. Just paste your URLs into the box, hit “Check,” and we’ll tell you what’s up—no fluff, no sign-up, no wait.

How It Works (And Why It’s Super Useful)

This tool is stupid simple. Here’s what you need to do:

  1. Paste your URLs (one per line)
  2. Click “Check”
  3. Get your HTTP status codes almost instantly

That’s it. You’ll see whether a page is alive (200), redirected (301 or 302), not found (404), or throwing a server tantrum (500+). Super helpful when you’re fixing SEO errors or trying to clean up an old site.



And look—don’t paste hundreds of URLs here. It’s not built for that. Stick to 10 or fewer at a time. If you’ve got a whole domain to crawl, go use Screaming Frog or something built for scale.

What This Tool Checks

Once you hit “Check,” here’s what our backend quietly grabs and shows:

1. HTTP Status

Every URL gets a code. 200 is good. 404 means the page’s gone. 503 means the server’s basically on a coffee break. It’s fast, clear, and you don’t need to be a dev to understand it.

2. Host

We show you the hostname (aka the domain). This helps you track down where that link is actually coming from. It’s not always what you expect, especially if you’re running redirects or dealing with CDNs.

3. Full HTTP Code

We show the exact number, and if you’re new to this stuff, don’t worry. You’ll get used to it fast. A few common ones:

  • 200: All good
  • 301: Permanent redirect
  • 302: Temporary redirect
  • 404: Page not found
  • 500: Server error

Common Status Codes Explained (The Real-World Way)

Here’s a quick breakdown you can actually use:

🔹 1xx – Informational (honestly, you rarely deal with these)

These just mean “hey, we got your request, hold tight.”

  • 100 Continue – Request received, keep going.
  • 101 Switching Protocols – Changing connection method (like to WebSockets).
  • 102 Processing – Server’s working on it.
  • 103 Early Hints – Prepping some headers before the final response.

🔹 2xx – Success (aka what you want to see)

  • 200 OK – Everything’s good. Page loaded fine.
  • 201 Created – A new resource was made (like after a form submit).
  • 202 Accepted – We got it, but it’s not done processing.
  • 203 Non-Authoritative Info – Data returned, but it’s from a third party.
  • 204 No Content – Server responded, but no body returned.
  • 205 Reset Content – Like 204, but also tells the browser to reset the form.
  • 206 Partial Content – Used for range requests (like streaming).
  • 207 Multi-Status – Multiple statuses returned in a batch (used in WebDAV).
  • 208 Already Reported – Repeated info in a response (WebDAV again).
  • 226 IM Used – Server performed a transformation (rare).

🔹 3xx – Redirection (some of these are fine, too many? Not so much)

  • 300 Multiple Choices – The URL points to multiple resources.
  • 301 Moved Permanently – Permanent redirect. Safe for SEO.
  • 302 Found – Temporary redirect. Don’t overuse this.
  • 303 See Other – Redirect to another resource using GET.
  • 304 Not Modified – Use cached version, no need to reload.
  • 305 Use Proxy – Client must use a proxy (deprecated).
  • 307 Temporary Redirect – Same as 302 but more strict.
  • 308 Permanent Redirect – Like 301 but with strict method rules.

🔹 4xx – Client Errors (your browser or the request is the issue)

  • 400 Bad Request – Something’s broken in the request.
  • 401 Unauthorized – You need to log in.
  • 402 Payment Required – Reserved for future use, but rarely seen.
  • 403 Forbidden – Server says nope, access denied.
  • 404 Not Found – Page doesn’t exist (you’ll see this a lot).
  • 405 Method Not Allowed – You tried the wrong request method (like POST instead of GET).
  • 406 Not Acceptable – Content not in acceptable format.
  • 407 Proxy Auth Required – Needs proxy authentication.
  • 408 Request Timeout – You took too long.
  • 409 Conflict – Request conflicts with server state.
  • 410 Gone – Page is gone forever, no redirect.
  • 411 Length Required – Request lacks content length header.
  • 412 Precondition Failed – Headers don’t match server expectations.
  • 413 Payload Too Large – Request body is too big.
  • 414 URI Too Long – URL is too long to handle.
  • 415 Unsupported Media Type – Server doesn’t like the content type.
  • 416 Range Not Satisfiable – Requested range can’t be fulfilled.
  • 417 Expectation Failed – “Expect” header can’t be fulfilled.
  • 418 I’m a teapot – Joke code from an old April Fool’s RFC.
  • 421 Misdirected Request – Request was sent to the wrong server.
  • 422 Unprocessable Entity – Server understands but can’t process it (common in APIs).
  • 423 Locked – Resource is locked.
  • 424 Failed Dependency – Previous request failed, so this can’t proceed.
  • 425 Too Early – Trying to replay the request too soon.
  • 426 Upgrade Required – Client needs to upgrade protocol (like to HTTPS).
  • 428 Precondition Required – Missing conditions in headers.
  • 429 Too Many Requests – You’re rate limited. Chill.
  • 431 Header Fields Too Large – Your headers are too big.
  • 451 Unavailable for Legal Reasons – Blocked for legal reasons (DMCA, etc.).

🔹 5xx – Server Errors (yep, these are the server’s fault)

  • 500 Internal Server Error – Something broke. Fix ASAP.
  • 501 Not Implemented – Method not supported by the server.
  • 502 Bad Gateway – Server got a bad response from another server.
  • 503 Service Unavailable – Server’s down, overloaded, or doing maintenance.
  • 504 Gateway Timeout – One server waited too long for another.
  • 505 HTTP Version Not Supported – Using an unsupported HTTP version.
  • 506 Variant Also Negotiates – Server can’t pick a variant.
  • 507 Insufficient Storage – Server ran out of space (yikes).
  • 508 Loop Detected – Infinite loop on the server side.
  • 510 Not Extended – Server needs more extensions to fulfill the request.
  • 511 Network Authentication Required – You need to authenticate to access the network (think captive Wi-Fi portals).

When You Should Worry

Here’s where things get tricky—and important.

  • 3xx codes aren’t always bad, but too many redirects slow down your site.
  • 4xx codes hurt your SEO and user experience. Fix them ASAP.
  • 5xx codes mean something’s broken on your server side. These need urgent attention.

If your URLs are throwing any of these errors, you’re losing traffic or messing up user trust (or both). Prioritize fixing those before worrying about fancy design tweaks.

Want To Check a Whole Website?

Use a crawler like Screaming Frog. It’s free for up to 500 URLs and way better than doing this manually if you’re managing a big site. I personally use it when running audits—it’s like X-ray vision for your website.

Quick Screaming Frog Setup:

  1. Install it
  2. Go to Configuration > Spider
  3. Tick “Check Links Outside Start Folder”
  4. Enter your URL and hit Start

Once done, check the Response Codes tab. You can even export the list and start cleaning up links in Google Sheets or Excel.

FAQ: HTTP Status Codes

What is an HTTP status code, really?

It’s how a server tells your browser what happened when you requested a page. It’s kind of like a conversation. “Hey, this page exists” (200), or “Nope, can’t find that” (404), or “Sorry, we’re down” (503).

Can I fix a 404 error?

Usually yes. Either bring the page back, or redirect it somewhere useful.

Is 301 better than 302?

Depends on your intent. 301 is permanent, and better for SEO. 302 means “temporary” and can confuse search engines if used wrong.

Why does my page show 500?

That’s a server issue. Could be bad code, overloaded server, or misconfigured settings. You’ll need to check logs or ask your host.
