—What Is an HTTP Status Code?
An HTTP status code is a three-digit response code sent by a web server to indicate the result of an HTTP request.
These codes help browsers, applications, developers and search engine systems understand whether a request was successful, redirected, rejected, or affected by a server-side problem.
Common HTTP Status Codes
OK
The request was successfully processed.
Created
The request resulted in a new resource being created.
No Content
The request succeeded but the response contains no content.
Moved Permanently
The requested resource has a permanent redirect.
Found
The resource is temporarily available at another URL.
Not Modified
The cached representation can be used because the resource has not changed.
Bad Request
The server cannot process the request because it is invalid.
Unauthorized
Authentication is required or has not been successfully provided.
Forbidden
The server understood the request but refuses to fulfill it.
Not Found
The requested resource could not be found.
Too Many Requests
The client has sent too many requests in a given period.
Internal Server Error
The server encountered an unexpected condition.
Bad Gateway
A gateway or proxy received an invalid response from an upstream server.
Service Unavailable
The server is currently unable to handle the request.
How to Use the HTTP Status Code Checker
Step 1: Enter a URL
Enter the complete website address, including https:// when applicable.
Step 2: Start the Check
Click the Check Status button.
Step 3: Review the Result
If the browser can access the URL and the website permits the request, the tool will display the available HTTP status information.
Step 4: Understand the Code
Use the HTTP status reference on this page to understand common response codes such as 200, 301, 302, 404 and 500.
Why HTTP Status Codes Matter
HTTP status codes are useful for website maintenance, debugging and understanding how web requests are handled.
Website Troubleshooting
A 4xx response can indicate a problem with the request or requested resource, while a 5xx response can indicate a server-side issue.
Redirect Checking
3xx status codes are associated with redirection and caching behavior. Developers can use them when troubleshooting URL changes and website navigation.
Developer Testing
Developers can use HTTP status information while working with websites, APIs and web applications.
Website Maintenance
Checking URLs can help identify resources that may require further investigation when users report access problems.
Important Limitations
This is a browser-based HTTP status checking tool. Modern browsers enforce same-origin and cross-origin security rules.
A target website may block or restrict cross-origin requests. If that happens, this page may not be able to read the target's HTTP response status.
Therefore, a browser-side request failure does not necessarily mean that the target website is offline or returning an error.
Privacy and Data Processing
The URL entered into this tool is used by the browser to attempt the requested check.
The core page does not require you to create an account to use the checker. Normal website infrastructure and any enabled third-party services may process technical information associated with visiting the page.
Avoid entering URLs that contain private tokens, passwords, authentication credentials or other sensitive information.

Frequently Asked Questions
An HTTP Status Code Checker attempts to request a URL and, when the browser is allowed to read the response, displays available HTTP status information.
HTTP 200 OK generally indicates that the request was successfully processed.
HTTP 404 Not Found indicates that the requested resource could not be found by the server.
HTTP 500 Internal Server Error indicates that the server encountered an unexpected condition while processing a request.
Browsers enforce cross-origin security rules. A website may block a browser-based request or prevent the response from being read by another origin even though the website itself is accessible.
Browser fetch behavior can automatically follow redirects, so the exact intermediate redirect chain may not always be visible through this client-side tool.
