Frequently Asked Questions
Account
How do I sign up?
You can sign up using your GitHub, Google, or Microsoft account, or with an email address and password.
What if I forgot my password?
Click the "Forgot Password" link on the login screen to reset your password.
Clusters
How long does it take to create a cluster?
Cluster creation typically takes 3-5 minutes. It runs in the background, so closing the dialog or the browser does not cancel it; you can follow it as "Create cluster" on the Background Jobs screen. If it is still running after 35 minutes, the dialog points you to Background Jobs for the final result. Please contact support if the job ends in a failed state.
See: Create a Cluster
What is the difference between K3s and RKE2?
- K3s - Lightweight and fast. Best for general workloads.
- RKE2 - Enterprise-grade with enhanced security. Recommended when compliance requirements apply.
K3s is recommended for most use cases.
See: Create a Cluster
What does the Health checks section on the cluster page show?
The health checks on the cluster detail page's Details tab look for common configuration drift. Which components are checked depends on the kind of cluster (K3s or RKE2).
| Component | What it means |
|---|---|
| longhorn | Whether Longhorn, which provides persistent volumes, is installed |
| storageclass | Whether Longhorn's StorageClass has been created |
| harbor-auth | Whether the credentials for pulling container images are present |
| traefik (K3s only) | Whether the port used to expose services is set correctly |
| ingress-webhook (RKE2 only) | Whether a stale setting that blocks Ingress creation is left behind |
K3s and RKE2 expose services differently, so the list differs between them. Components that do not apply to your cluster are not shown.
What do I do when a health check reports a problem?
Most of them can be fixed automatically by Doctor. Rows it can fix are marked "Doctor can repair", and a prompt above the table shows how many there are with a button to run it. Pressing the button attempts the repair.
There is one exception: if Longhorn is not installed, Doctor cannot fix it. Installing Longhorn is not something Doctor does — add it from the catalogue on the cluster's Services tab. The page says so when this is the case.
When everything is healthy no repair prompt appears. Doctor can still be run at any time from the button at the top of the page.
The backup "Size" looks as large as the VM's whole disk
What the list shows is the VM's logical disk size, not the space the destination actually uses. Backups are compressed and deduplicated where they are stored, so real consumption is considerably lower.
The effect is largest across nodes cloned from the same template: in one measured case, backups listed as 218 GiB in total occupied 26 GiB on the destination.

What happens to my data when I delete a cluster?
When you delete a cluster, all VMs, Pods, and data are permanently deleted. Please back up any important data before deletion.
Can I increase a VM's memory or CPU later?
Yes. On the Virtual machines tab of the cluster detail page, choose ⋮ → Edit on a VM to change its CPU, memory and disk. Memory moves in 1 GB steps; disks can only grow.
The VM stops while the change is applied. Changing the Primary node also stops the Kubernetes control plane, so pick a time when that is acceptable.
Steps and caveats: Virtual Machines
Can I add or remove worker nodes after creating a cluster?
Yes. You can add or remove worker nodes from the Virtual Machines tab on the cluster details page.
Adding a worker node runs in the background and takes a few minutes. Closing the dialog — or the browser — does not cancel it, and you can follow the progress on the Background Jobs screen. The new node appears in the virtual machine list once it finishes.
Billing & Payments
Is there a free plan?
No. There is currently no free plan available. Please check the plan selection screen for available plans and pricing.
See: Billing & Payments
Can I pay via bank transfer from outside Japan?
No. Only domestic bank transfers from Japanese banks are accepted. Please use a credit card for international payments.
What happens when I cancel a subscription?
The cluster will be automatically deleted at the end of the current billing period. You can continue using the cluster until the period ends.
Can I get a receipt?
For credit card payments, a receipt is sent by email after each payment. Receipts can also be downloaded from the billing settings page.
Applications
What types of applications can I deploy?
You can deploy most applications that include a Dockerfile in the repository.
What should I do if a deployment fails?
- Check the deployment logs for error details
- Verify the Dockerfile syntax and build process
- Confirm the correct branch is selected
- Contact support if the issue persists
See: Deploy Applications
What if a deployed app never starts (stays pending)?
The cluster may not have enough free CPU/memory.
- Open the app from the Services tab — the app details panel explains why it is waiting to start, including the fix when it is a resource shortage
- Free up capacity by deleting unused apps, or add worker nodes
- Apps whose catalog card shows a "May not fit free resources" warning can stay pending after deploy
See: Services (Catalog)
How long does it take for a custom domain (Vanity domain) to take effect?
After configuring a Vanity domain, changes typically take effect within a few minutes.
See: Custom Domains
Security
Is my data encrypted?
Yes. All communications are encrypted with TLS. Stored data is also encrypted.
Do you support two-factor authentication (2FA)?
If you sign in with an external account such as GitHub or Google, the two-factor authentication configured on that account applies automatically.
Other
How do I contact support?
Create a ticket from "Support" in the sidebar. We typically respond within 1-2 business days.
Where can I find the terms of service and privacy policy?
See the Terms of Use and the Privacy Policy. Links are also available on the sign-up screen and in the footer.
