Harmony Core on your machine, optional Cloud in a browser, and how model charges stay separate.

Harmony sells one local product and one optional hosted-compute plan. Model access is never bundled.

Outcome: you know which surface to install, whether you need an account, and who bills inference.

The two products

ProductWhat you getAccountMoney
Harmony CoreDesktop, nala TUI, and nala / harmony CLI on your computerNoFree. Not a trial of Core.
Harmony CloudOptional hosted Linux workspaces (Agent Hours)Yes, for Cloud onlyOne paid plan. Figures live only on pricing.

There is no public Harmony Pro SKU. People sometimes say “Pro” as shorthand for the paid product; the catalog name is Harmony Cloud. Harmony-routed Plus / Pro / Max model credits are not for sale. A Cloud subscription does not include tokens.

Where the agent runs

SurfaceWhere work runsTypical use
Harmony desktopLocal machineMulti-pane control, approvals, fleet
nala TUI / CLILocal machine, same daemonFocused session in a repo, scripts
This website / optional web app (PWA)Browser talking to Harmony CloudWatch or steer hosted jobs away from the development machine
Native iPhone / Android appsIn development. Not an App Store or Play Store download. Not desktop parity.

The website is the same Harmony account as Cloud on desktop. It is not a fourth local daemon and it does not run local terminals, MCP, or on-device voice.

Who pays the model

Harmony launches your agent CLI. That CLI authenticates with its provider, on the machine where the agent is running:

  • Core: sign in on your laptop (claude, codex login, or that vendor's equivalent). Network use and token spend go to that provider.
  • Cloud: sign in inside the workspace after it starts. Spend still goes to that provider. Harmony meters Agent Hours for the VM, not tokens.

Installed is not authenticated. Authenticated is not entitled. Harmony can see the binary; it cannot see your plan.

Core never stores those CLI keys. Cloud may store other secrets you add on Account → Secrets (clone URL / deploy key), encrypted with an operator key — not customer BYOK and not a model-key vault.

Cloud trial and paid checkout happen on the website, not by visiting a URL. Cloud quickstart covers /cloud/start (routing only) versus the explicit trial control and separate monthly/annual checkout.
