Web Page & RSS Checker
Enter an address and our server visits it to check titles, descriptions, Open Graph preview data, response headers, redirects and the SSL certificate expiry — inspect an RSS/Atom feed for common problems, or check whether an API allows browser requests from another site (CORS), and look up a domain's DNS records (A, MX, TXT, NS and more) through public DNS.
This tool makes our server visit the address you enter. The address and results are not stored or logged, and private or internal addresses are never contacted. Do not enter pages that need a login or addresses containing passwords.
How this works
- Our server visits the address you enter. Private IPs, internal networks and reserved addresses are blocked before connecting, re-checked at every redirect, and only the verified IP is used.
- The SSL certificate is read with verification left on. If the certificate is already invalid you get an error instead of an expiry date.
- Only the first 512 KB of the body is read. Types such as images and PDFs are cut off after the headers.
- Results and the address are not stored. To prevent abuse it is limited to 6 checks per minute per IP.
FAQ
Can it check pages that need a login?
No. It connects without credentials, so only public pages can be checked.
It opens on my site but says "cannot be contacted".
For security, private network addresses (192.168.x.x, 10.x.x.x …), localhost and names that cannot be resolved are never contacted.
Does it tell me my search ranking?
No. It only checks meta tags and the response status.
How to use this tool
Use it to check whether your site is shared and exposed correctly. Enter an address and the server visits it to check the title, description and OG preview data, response headers, redirect path and SSL certificate expiry, and it also checks the format and common errors of RSS/Atom feeds.
Frequently asked questions
What does it check?
The title, description and OG preview data, response headers, redirect path and SSL certificate expiry date.
Can it check RSS feeds?
Yes. The RSS feed tab checks the format and common errors of RSS/Atom feeds.
Can it check internal (private network) addresses?
The server connects on your behalf, so for security internal and private addresses cannot be checked. Enter only public addresses.

Code Formatter (Beautifier)
Tidy HTML, CSS, JS, JSON, PHP, Java, Kotlin, Shell, Python, SQL, XML and YAML with tabs or spaces (2, 4 or 8), then copy it or export it as colored HTML. Your code is never sent to the server.
Code Minifier
Remove comments and unnecessary whitespace from HTML, CSS, JS and JSON to cut file size. Paste code or open a file (drag and drop works), then copy the result or download a .min file. Your code is never sent to a server.
JSON, XML & YAML Parser
Paste or open a JSON, XML or YAML file to validate it (with the exact line and column of any error), browse it as a collapsible tree, search values and keys, look values up by path, pretty-print or minify it, and convert between formats. Everything runs in your browser — your input and files are never sent to a server.
CSS Generator
Build gradients, shadows (box/text-shadow), rounded corners (border-radius) and flex/grid layouts while watching them, then copy the CSS. Nothing is sent to a server.
Password Generator
Create a hard-to-guess password from a length and character types, or as an easy-to-remember word combination (passphrase). The result never leaves this page.
