Check how your website looks on any server IP before changing DNS records. The easiest way to test server migrations, hosting changes, and pre-launch sites.
No software to install, no host file editing, no complicated setup.
Type the domain name you want to preview and the IP address of the server you want to view it on.
HostCheck creates a unique URL that routes your request through our proxy with the correct Host header.
Click the link and navigate the full website as if DNS had already been updated. All pages, styles, and images work.
Everything you need to preview websites with confidence.
Generate a working preview link in under 5 seconds. No waiting, no queues.
Preview without touching your live DNS. Your production site stays completely unaffected.
Send preview links to clients and colleagues. No technical setup needed on their end.
Browse the complete website — internal links, images, CSS, and JavaScript all work through the proxy.
Moving hosts? Verify everything works on the new server before pointing your domain.
We never store your data. Preview sessions are completely transient and private.
Trusted by developers, sysadmins, and agencies worldwide.
Migrating from one host to another? Check the new server renders everything correctly before switching DNS.
Built a new site on a staging server? Preview it with the real domain to catch issues before going live.
Need to check if an issue is server-specific? Preview the same domain on different IPs to isolate the problem.
Share a preview link with your client so they can see the new site before you make the DNS switch.
We act as a reverse proxy. When you open a preview link, our server fetches the page from your
specified IP address while sending the correct Host header for your domain. This
tricks the target server into serving the right website, just as if DNS pointed to it.
Yes, completely free. No sign-up, no limits, no hidden costs. We plan to keep the core tool free forever.
The preview proxy connects to your server over HTTP by default. Most servers will still respond correctly. Full HTTPS support is on our roadmap.
Absolutely not. HostCheck only reads from the server you specify. It makes no changes to your DNS, hosting, or server configuration.
Yes! Preview links are just regular URLs. Copy and share them with anyone — they'll see the same preview without needing any setup.
It's free, instant, and requires zero setup. Just enter your domain and IP.
