How it ends, how to cancel it, and how to lift the limits. Your first plan starts with a free 7-day trial. Checkout asks for a card. **There is no free tier without a card.** | Rule | Trial | After the first payment | | - | - | - | | Length | 7 days, then Stripe charges the plan | - | | Card | Required at checkout | - | | Compute | 25 hours in total, all sandboxes together | The plan's [included time](/pricing#plans) | | Sandboxes at once | 2 | The plan's limit, 100 or more | | Starts (create, fork, resume) | 5 per minute, 25 per hour, 75 per day | 12 / 60 / 200 or more | | Auto-stop | Required, 2 hours maximum | Up to 30 days, or off | | Sizes | `small` and `default` | All sizes. `xlarge` needs the \$100 plan or higher. | * Stop, resume and fork do not reset the 25 hours. * A resume gives the sandbox a new auto-stop window of 2 hours or less. * The trial limits stay until the first payment. * A change to another plan during the trial ends the trial. Stripe charges the new plan at once. * `boat limits` shows the trial limits and the hours that you have left. ## Who gets a trial * A person gets one trial. An account that subscribed before restarts the plan with no trial. * Organizations get no trial. An organization plan is paid from the first day. * Boat can refuse a trial to an identity that looks like a repeat sign-up. The error is `trial_blocked`. If this is wrong, [contact support](/support). ## End the trial early Pay now to lift every trial limit at once: 1. Open [Dashboard > Billing](https://boat.dev/dashboard?tab=billing). 2. Click **Upgrade now**. Stripe charges the plan price at once. The 7-day period then ends, and the first month starts that day. Are you a member of an organization that pays? Then switch to it with `boat org switch `. Its sandboxes do not use your trial limits. ## Cancel the trial | How | What happens | Charge | | - | - | - | | **Cancel trial** on [Dashboard > Billing](https://boat.dev/dashboard?tab=billing) | The trial ends now. Boat stops your running sandboxes. Their disks stay. | None | | Cancel in the Stripe portal (`boat billing portal`) | The trial runs until its end date, then ends. | None | After a cancel, **Upgrade now** no longer works. To keep using Boat, subscribe again from the Billing tab. You get no second trial. ## Errors you can get during the trial | Status | Code | Cause | Fix | | - | - | - | - | | `400` | `trial_auto_stop_required` | No auto-stop, or an auto-stop above 2 hours | Set `--ttl 7200` or less, or end the trial. | | `403` | `trial_machine_class_not_allowed` | You asked for `large` | Use `default`, or end the trial. | | `429` | `limit_reached` | 2 sandboxes already run | Stop one, or end the trial. | | `429` | `rate_limited` | 5 starts in the last minute, 25 in the last hour, or 75 in the last day | Wait, or end the trial. | | `429` | `trial_compute_limit_reached` | You used the 25 hours | End the trial. | For every limit and error after the trial, read [Limits and errors](/limits).
