Accounts & Plans
Dynamo runs on a Dynamo Engine account. Your subscription covers the product; the AI itself is bring-your-own — your own provider API keys — billed by your provider, separately.
Do I Need an Account?
Yes. Dynamo requires a signed-in Dynamo Engine account with an active subscription or trial. New accounts get a 7-day Personal trial when they first sign in to the app — one per account and computer, no card needed.
What the account covers vs. what your provider covers:
- Dynamo Engine subscription — the product: the app, the command line, the Unity integration, updates, and your device seats.
- Your AI provider — model usage. You pay Anthropic / OpenAI / Google / etc. directly with your own key, or use local models via Ollama for free. Dynamo doesn't mark up or resell AI usage.
Signing In

The app signs you in on first run. Your account and plan are under Settings → Account.
On the command line:
/login # start the sign-in flow
/logout # sign out on this device
/whoami # show who you're signed in as and your current plan
/subscribe # open the plans pageOr from your shell:
dynamo login
dynamo logout
dynamo whoami
dynamo subscribeDevices & Seats
Dynamo seats are device-based — each machine you sign in on registers as a device under your license (Personal includes 3). Manage them from the CLI:
dynamo account devices # list registered devices (marks this one)
dynamo account revoke <id> # revoke a specific device
dynamo account portal # open your customer portal in the browserUse account revoke to free up a seat when you stop using a machine, then sign in on the new one.
Billing
During or after the trial, subscribe from your account page; the customer portal opens once you have a subscription.
dynamo account portal opens your hosted customer portal, where you can update payment details, cancel or resume your subscription, and review invoices. The same portal is reachable from your account page.
Your data
From your account page you can also:
- Export your data — download a ZIP with your account info, subscription, devices, billing history, and account activity.
- Delete your account — a 30-day grace period applies. Signing back in shows the countdown; it does not stop it. To cancel a scheduled deletion, email support@dynamoengine.dev before the window closes.
Billing dates (trial end, scheduled cancellation, deletion grace) are shown in UTC on the account page and in emails, so both surfaces always agree.
