Check if any website is down right now

Pingzr is a free browser-based tool that checks whether websites are reachable from your network in real time. Paste any URL, hit Check, and get an instant online/offline/timeout result - no install, no sign-up required.

How it works

Pingzr uses your browser to send a request to each URL. If the server responds, the site is marked online. If the connection is refused or the network is unreachable, it's marked unreachable. If the server takes too long, it's marked timeout. Results reflect reachability from your location and network, not a third-party server.

What can I check?

Pingzr comes pre-loaded with 115+ popular websites across categories: search engines, social media, video platforms, developer tools, cloud services, banking, e-commerce, news, and more. You can add any custom URL and remove or edit any default entry.

Frequently asked questions

Why does a site show as unreachable when it loads fine in my browser?: Some websites block cross-origin requests from other domains. The site may be fully online but configured to reject requests that don't come from a normal browser navigation. This is a CORS restriction, not a real outage.
Why does a site show as online when it's actually down?: Pingzr checks reachability from your browser and network. If the site is down only in certain regions or on certain ISPs, your check may still succeed. Use it alongside other tools for confirmation.
Is this different from ping?: Yes. Traditional ping uses ICMP packets, which browsers can't send. Pingzr uses HTTP fetch requests - the same mechanism your browser uses to load websites. This is a more realistic test of whether a web service is actually accessible.
Can I check sites behind a VPN or firewall?: Yes. Pingzr runs entirely in your browser, so it checks from wherever you are, including VPN connections. This makes it useful for testing whether a site is blocked on your network.
Does Pingzr store my data?: Your site list is saved to your browser's localStorage by default. If you sign in with Google, it syncs to your account via Firebase. No site list data is sent to third parties.

Popular sites you can check

Google, YouTube, Facebook, Instagram, Twitter / X, Reddit, GitHub, Netflix, Spotify, Amazon, Wikipedia, Cloudflare, Discord, Slack, OpenAI, Anthropic, LinkedIn, TikTok, Twitch, and 95+ more.

Your data, your control

Pingzr works in two modes. In local mode, your site list is saved only to your browser - nothing leaves your device. If you sign in with Google, it switches to synced mode and your list is backed up to your account so it stays consistent across all your devices. You can switch between modes at any time, and signing out returns you to local mode instantly.
