The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

The pattern recognizes a scheme, authority, optional port, path, query, and fragment using a practical URI subset. Full-input anchors are used, but DNS resolution and URL safety checks are not.

  • HTTP and HTTPS cover common web links.
  • A practical subset stays readable compared with the entire URI grammar.

When to use this

Link forms, crawlers, and Markdown linters check web URLs.

Edge cases

  • Spaces need percent-encoding.
  • Internationalized domains can use Unicode or punycode.
  • A valid URL can still be dead or unsafe.
