Pagelet turns any HTML file into a live URL on your own subdomain — free, no account needed. Drag a file on the homepage or paste your code.

About the SSL Checker

Inspect the TLS certificate of any domain: who issued it, when it expires, how many days are left, and whether the chain validates. Useful before pointing a custom domain at your Pagelet Pro site, or for quickly auditing any site's certificate hygiene.

How to use it

  1. Enter a domain name (no https:// needed).
  2. Press Check — the certificate details appear instantly.
  3. Watch the days-remaining value so renewals never surprise you.

Frequently asked questions

What does 'valid chain: no' mean?

It means the certificate isn't trusted by standard roots — typical for self-signed certificates, expired certs, or missing intermediate certificates.

Do custom domains on Pagelet get SSL?

Yes — Pro sites with custom domains get HTTPS certificates automatically.
