State you can inspect
Desired state lives in a database and a reconciler records a status condition with a reason after every pass, so you can see why something is not ready.
Kamal alternative
Zero-downtime deploys, plus a control plane you can see
Kamal is deliberately minimal: no server component, just SSH from your machine or CI. Levelrail keeps readiness-gated cutover and adds a dashboard, history, rollback and observability.
curl -fsSL https://levelrail.com/install.sh | sudo sh
What a control plane adds
History and rollback
Every deploy is recorded with its pinned image. Rolling back is switching to an image that is still there.
No SSH from CI
Servers run an agent that dials out to the control plane, so CI talks to the API with a scoped token instead of holding SSH keys.
Kamal and Levelrail, side by side
Kamal is a sharp tool for people who want the fewest moving parts. These are the design differences.

From a deploy script to a platform
- 1
Install the control plane
One script on a Linux server.
- 2
Deploy an image
Use the CLI or the dashboard and watch the readiness gate.
- 3
Wire CI to the API
Use a scoped API token from GitHub Actions or any pipeline.
Frequently asked questions
Is Levelrail heavier than Kamal?
Yes, by design: it is a control plane with a database and a dashboard, while Kamal has no server component. The control plane idles at a small footprint, which the case studies page measures.
Can I deploy from CI without SSH?
Yes. CI calls the API or CLI with a scoped token. See the GitHub Actions guide.
Is there an importer for Kamal?
No. You point Levelrail at the same images and recreate configuration.
Is it free?
Yes. Apache 2.0, one edition.
