Free URL Status Checker

Is that page actually returning 200 — or silently 404ing? Browsers block cross-origin status checks, so NToolHub's URL Status Checker gives you the next best thing that's actually real: copy-paste curl commands for status codes and timing, a browser-based checker link, and a plain-English status-code guide.

ℹ️
Why no live result here? Fetching arbitrary URLs from a web page is blocked by CORS unless the target server explicitly permits it — which most sites don’t. Instead, this tool builds the exact commands and one-click lookup links you need — everything runs from your own terminal or trusted lookup services.
Private by design. This page performs no live network lookups and uploads nothing — it only generates commands and links that run on your own machine or on trusted lookup sites you open yourself.

How to Use the URL Status Checker

  1. Paste the URL you want to check.
  2. Click Get Status Commands for curl one-liners.
  3. Run the command — a 200 means healthy, 3xx/4xx/5xx need attention.
  4. Use the timing variant to spot slow pages too.

Features

Enter any URL for curl one-liners returning just the status code, code-plus-timing, or redirect-aware results — plus an httpstatus.io link and a reference table decoding 2xx/3xx/404/5xx responses.

Benefits & Use Cases

You verify real server responses instead of trusting a proxy's cached guess — catching soft-404s, redirect loops and slow pages with commands you can script into monitoring.

Tips

A 200 with 'not found' text is a soft 404 — fix it; log response times alongside codes to catch performance regressions; re-check after migrations.

Frequently Asked Questions

Why can't the page check the status itself?

Fetching arbitrary URLs from JavaScript is blocked by CORS on most sites. Curl runs outside the browser with no such restriction — that's the honest way to check.

What's a soft 404?

A page returning HTTP 200 while displaying 'not found' content. It wastes crawl budget and confuses users — return a real 404 status instead.

How do I check many URLs at once?

Save the curl command in a loop over a URL list, or use Screaming Frog / Sitebulb for bulk crawling. This tool is for quick one-off checks.

Is 301 or 308 better for redirects?

Both are permanent; 308 additionally preserves the request method. For SEO purposes they're equivalent — pick one and be consistent.
