# Get a licence (https://optakt.ai/docs/licence)

Optakt One needs a licence key to install and to run. This holds for every plan, Free included.

## During preview access [#during-preview-access]

There is no online checkout yet. To get a licence, write to [max@optakt.io](mailto:max@optakt.io) with:

- your name,
- the plan you want: Free, Solo or Team,
- for Team, how many users.

We send you your licence key by email.

## The plans [#the-plans]

| Plan | Price | For |
| --- | --- | --- |
| **Free** | €0 | One person, one space |
| **Solo** | €25 per month | One user, with a space for every project, client or theme |
| **Team** | €20 per user per month, from two users | A team with members, roles and shared spaces |

Every plan runs the whole system. The plans differ only in how many users, agent scopes and spaces the licence allows. The details are under [Plans and licences](/docs/plans).

Model costs are not included: your model provider bills you directly, under your own key or subscription.

## Where the key goes [#where-the-key-goes]

The installer asks for the key on its first run and checks it before it downloads anything. It keeps the key in `~/.optakt/license`, readable only by you. Later runs read it from there.

To replace a key, open the [admin app](/docs/admin-app), go to Settings and press `l`.

A licence runs on one machine.
