Plans and license keys

L4 on your own infrastructure is free. A free Server has the full product with one Space, and no limit on people, history, Tasks or Agents.

A Business key adds unlimited Spaces, and company features as they arrive. It is one flat subscription per Server, with no charge per person.

Add a key

1. In Server settings > Plan, copy your Server UUID.
2. Buy Business for that UUID on llll.gg. Your billing page then shows a license key.
3. Paste the key under Server settings > Plan.

Only the Server Owner can see or change the plan. A key works only on the Server UUID it was bought for, and any other Server refuses it.

Your Server stays private

A key is checked on your Server, offline. Nothing is sent to L4 when a key is added or checked.

A key lasts until shortly after the paid period ends, so each period needs a new one. Either paste it from your billing page, or turn on Renew the key automatically. It is off unless you turn it on. When on, near the end of a period your Server sends its UUID and current key to llll.gg, and nothing else.

When a key expires

If a payment fails or you cancel, Business keeps working through a grace period: 14 days after a failed payment, 7 after a cancellation. After that:

• Your Server and everything in it keep working. Chat, Tasks, Agents, files and Data are not affected.
• Every Space stays. Spaces beyond the first are not deleted or hidden, and people keep using them.
• Only creating another Space is refused, and changing the settings of company features.
• Company features you already set up keep working. Sign-in in particular never changes because a key expired.

Paste a current key at any time and everything is available again.
