Licence & activation

There is one thing to buy: a seat. A seat costs €19 + VAT a month, or €190 + VAT a year — a year is ten months’ price. The EUR base price is the same each period; there is no separate first-year or renewal price. EUR is the only defined price. Where available, Stripe shows a converted local-currency amount at checkout using its current exchange rate. The first seven days are free: you provide a card when starting the trial, and the first payment is collected after it ends. There is no setup fee. The subscription renews automatically on the same date each period until you turn renewal off, which you can do yourself in your account at any time.

One seat is the Individual plan: owner-level tools in your own application, and no workspaces. Two or more seats are the Team plan, and two is a valid team — one person and one digital member. Up to one fewer than your seats can be workspaces, because one seat is always a person handing out work.

A workspace is the computer running the AI plus the people attached to it. The account that runs it is its digital member, and that account signs in on the machine — there is no licence key to type. Buying creates your first workspace; the owner creates the rest up to the ceiling. Each workspace is one Runtime — one active computer and one AI worker at a time — with its own worker and its own history, so two workspaces never share state.

A workspace stays live while your subscription is live and it is inside the ceiling, counted oldest first. If you end up with more workspaces than seats allow, the ones above the ceiling stop starting work. Nothing is deleted, and they come back as soon as there are seats for them again.

The subscription covers the software, its updates and its security fixes. Turn renewal off and Harness keeps working to the end of the term you have already paid for. After that it stops starting new work — no manual runs, no scheduled ones — while work already running finishes safely. Nothing on your machine is deleted: settings, results, routines and the full audit history stay readable and exportable, and the work it already produced stays yours.

Replacing a computer is free and self-service, with no limit on how often: release the old machine in your account, and the digital member signs in on the new one.

• Registration is refused. That workspace already has a machine, or the account signing in is not its digital member. Release the machine in your account, or name the right digital member.
• The computer hardware changed. Release the machine in your account and sign in again on the rebuilt one. Transfers are self-service and there is no limit on them.
• A workspace stopped starting work. There are more workspaces than seats allow. Add a seat or remove a workspace — the ceiling is one fewer than your seats, counted oldest first. Nothing is deleted either way.
• Routines stopped running. The subscription ended, or a payment failed and the grace period ran out. Nothing on your machine is deleted; pay again and the same workspace starts working.
• A payment failed. Harness keeps running through the 30-day grace period. Update the card in your account and nothing is interrupted.
