Codes that outlive your server

LinkACode

Hand out eight characters instead of an address. Point the code at your server and switch it off, or back on, whenever you like. Everyone using it keeps the same code, and nobody sees what sits behind it.

Link your playlist DNS to Vizi Player

Shorten your playlist DNS into a LinkACode ID. Whoever you give it to adds the ID in Vizi Player and the playlist loads, without them ever seeing the address behind it.

  • No limit on how many people use one ID
  • Your DNS is never shown in the app, and is stored encrypted
  • Switch it off, or back on, whenever you like

Three steps

How it works

  1. Take a code. One, or a group of five for a set of servers. Use the code we assign, or word your own.
  2. Point it at your server. A hostname and a port, entered in your account. Change it whenever you like, free.
  3. Give out the code. Every code comes with a share card — the code and a QR, nothing else — ready to send to customers.

Why a code

Why a code rather than an address

Your address stays yours

Customers get eight characters. The server behind it is never shown to them, printed on anything, or recoverable from the code.

Nothing to re-issue

Everyone who already has the code follows automatically, with nothing to reinstall and nothing to retype.

Off means off

Switch a code off and it stops resolving within a minute. A revoked code and one that never existed look identical from outside.

No one is counting your customers

We keep a daily total per code so you can see it is being used. We do not keep a record of who used it or when.

Pricing

Single code

£30/year

One code standing in for one server.

Custom code

£50/year

One code, worded how you want it.

  • Choose 6 to 20 letters and numbers
  • e.g. LENDING or SKYLINE24
  • Yours as long as nobody has taken it
  • Change where it points whenever you like, free
  • A share card with a QR code, ready to send

Group of 5

£80/year

Five codes in a run, for a brand with several servers.

  • Five codes sharing two letters, numbered in order
  • e.g. KQ481203 to KQ481207
  • A different server behind each one
  • Change where any of them points whenever you like, free
  • A share card for each code
  • Group codes only work with codes in the same group. They cannot be mixed with other groups or with single codes. To mix and match, buy them as single codes.

  • e.g. LEND12, LEND13, LEND76, LENDGB, LEND876JH
  • A different server behind each one
  • Change where any of them points whenever you like, free

Developers

Usage-based

For apps that let people add a server by typing a code.

  • People type eight characters, not an address
  • Nothing to retype when a server moves
  • Access granted case by case
  • Priced on how many calls your app makes
  • Details shared once access is agreed

Prices are per year, and nothing renews by itself. A code keeps working for as long as you renew it; left to lapse, it stops resolving exactly as though it had been switched off. Changing where a code points is free, whenever you like, on any kind of code.

How they combine

Single codes and groups

A single code works alongside your other single codes: someone can add two of them in the same app and see both servers together.

A group is five codes meant to be used as one set. They work with each other and not with anything else, so a customer holding one of your group codes can add the rest of the group but cannot mix in a code from elsewhere.

Apps enforce this and explain it to the person, so nobody is left wondering why a code was refused.

For app developers

Building an app?

Apps can take a LinkACode code from the person using them and get the server behind it from us, so your users type eight characters instead of an address and never retype it when the seller moves.

Access is granted case by case and priced on how many calls your app makes. Tell us what you are building and we will come back to you.
