FAQ

Is Harmony still free?

Yes. Harmony Core is free, runs on your machine, and needs no account. Harmony Cloud is an optional paid addition. Nothing in this section changes the free product.

Do I need an account?

Only for cloud features. Local Harmony never asks for one.

Does my code leave my machine?

Only what you explicitly send to a cloud workspace, when you send it, after a review that lists every file. Credential files — SSH keys, cloud config, .env files, key material — are refused when the transfer is built, and that refusal cannot be overridden.

What runs in the cloud, and what does not?

A cloud workspace is a machine with your repository on it: a shell, a filesystem, your toolchain, a prompt queue, your agent, and the ability to bring the work back.

The agent is your agent. A workspace comes with Claude Code and Codex CLI installed and signed out. You sign in inside the workspace, with the same subscription you already pay for, and that agent works your queue while your laptop is closed.

You can also start a workspace with no agent at all. That is a remote machine with your repository and a terminal, which is a reasonable thing to want.

Do I pay Harmony for model usage in the cloud?

No. Harmony sells the machine — measured in Agent Hours — and never resells model access. Your prompts go from the workspace to your provider on your own account, exactly as they do on your laptop, and we neither see them nor bill for them.

How does my agent get signed in, if you never hold my key?

You sign in from inside the workspace. Open its terminal and run claude or codex login, and complete the provider’s own login. The credential is created by the provider on that machine.

It never passes through our servers, it is never typed into a Harmony screen, and nothing copies it from your laptop. It also cannot come back out: the directories those agents keep credentials in are excluded from everything a workspace captures or brings home, so a result can never carry your key with it. Deleting the workspace deletes the credential with it.

What does an Agent Hour measure?

Time a workspace is running, weighted by its machine class. Paused time is not counted. A workspace that fails to start is not counted. The included hours, the machine classes and the overage rate are on the pricing page.

What happens when I run out of hours?

Running workspaces pause; nothing is deleted. You can turn on extra hours with a cap you choose, or wait for the period to reset. Local Harmony is unaffected.

How do I cancel?

On the website, under Account → Billing. You keep access until the period you paid for ends. Workspaces and their data are kept for the retention period on the pricing page, then deleted.

Can I delete everything?

Yes: Account → Delete account. See Data handling for the order in which things go.
