L K J Beta

Your link, on another screen.

  1. Create a code on your phone or computer. Paste a URL and complete the browser check. No sign-up.
  2. Open lkj.st or lkj.cx on the other device.
  3. Enter the four-digit code and choose Find my link.
  4. Check the destination, then choose Open website.

The same code works with both domains. No account or app is needed to open it. New four-digit codes expire after one hour without an Open website request. An opening restarts that hour; simply viewing a preview does not. Unused numbers are allocated first. Once they are all used, the oldest expired codes may be reused after at least 30 days. Saved links include a version suffix so they cannot open a replacement destination.

Made for awkward keyboards

L, K and J are neighbours on QWERTY and consecutive in reverse alphabetical order. The two addresses complement that pattern: S–T for alphabetical keyboards and C–X for QWERTY. Actual keyboard layouts vary.

TV view provides a large number pad with arrow-key navigation. The normal form works without JavaScript. The final digit never sends you away automatically. Existing six-digit codes still work.

Common questions

Is LKJ free, and do I need an account?

Creating and opening codes is free during the beta. No account or app download is needed. An HTTP-capable AI agent can also create a code.

How long does a short link last?

New four-digit codes expire after one hour without an Open website request. An opening restarts that hour. Simply viewing the preview does not extend it.

Can I open a URL on a smart TV?

Yes, if the TV or streaming device has a web browser. See the step-by-step TV link guide. LKJ does not install a TV browser or cast content.

Is a destination guaranteed safe?

No. Checks can find some known threats, but they do not prove a website is trustworthy. Read the hostname and the explanation of checks before opening.

A note on privacy

A short code is easy to guess. Use LKJ for public websites, not confidential links or authentication tokens. The destination page always shows the actual hostname and gives access to the full URL.
