DeployCloud vs Kamal

Kamal (from the team behind Rails and Basecamp) deploys Docker containers over SSH to machines you provision and maintain, with zero-downtime rollouts behind a proxy — all driven from a `deploy.yml` and a CLI. It is excellent at what it does. But Kamal only handles the deploy step: you still operate the server, patch the OS and Docker, wire up TLS and a proxy, and stand up your own database and monitoring. DeployCloud keeps the same git-push simplicity as a **fully managed** platform — we build, run, scale and monitor your app on our cloud, so there is no server to operate and nothing to page you at 3am.

Managed platform vs deploy tool

Kamal is intentionally minimal: you write a deploy.yml, run kamal deploy, and it SSHes into your machines, pulls your image and rolls it out with a health-checked proxy. Powerful — but everything around that deploy is yours to operate: the server, the OS and Docker patches, the TLS certificates, the proxy, the database, the metrics. DeployCloud takes the opposite approach. You connect a Git repo and push; we build the image, run it on our infrastructure, terminate HTTPS, scale it and monitor it for you. Same simple developer experience, none of the sysadmin work.

What DeployCloud runs for you

  • A managed dashboard. See every app, its releases, live logs and metrics in one place — no editing YAML, no reading SSH output, and nothing for you to host or patch.
  • Git push to deploy. Connect a repo and push; DeployCloud builds with Nixpacks or your Dockerfile and ships it automatically. Kamal expects you to build and push images yourself.
  • Preview environments. A live URL per branch with GitHub commit status and a PR comment, provisioned and torn down for you.
  • Managed add-ons. Provision Postgres, Redis or S3-compatible storage in a click, with connection strings wired into your env — and we run, patch and back them up. With Kamal you stand those up and operate them yourself (Kamal has accessories, but you configure them).
  • Monitoring and backups, run for you. Time-series metrics, threshold alerts, log drains, and scheduled Postgres backups with one-click restore — no exporters or cron jobs to assemble.

Honest take: if you enjoy operating infrastructure yourself and want a dependency-free CLI that rolls images onto machines you manage — owning the build, the database, the patching and the monitoring — Kamal is superb and refreshingly simple. If you love that git-push simplicity but do not want to be the sysadmin, DeployCloud gives you the dashboard, preview apps, managed add-ons, metrics and backups as a fully managed service — nothing to provision, patch or monitor.

Frequently asked questions

Is Kamal a PaaS?

Not quite — Kamal is a deployment tool. It rolls Docker containers onto machines you operate over SSH with zero downtime, but it has no dashboard, preview environments, managed add-ons or built-in monitoring, and you run and patch the servers behind it. DeployCloud is a fully managed platform that builds, runs, scales and monitors your app for you.

Do I have to run any servers with DeployCloud?

No. DeployCloud is fully managed — you connect a Git repo and push, and we build, host, scale and monitor your app on our cloud. There is nothing to provision or patch. Kamal is the opposite: it runs from your laptop or CI and deploys onto machines you operate and maintain yourself.

Can I get preview environments with Kamal?

No. Per-branch preview environments with GitHub PR feedback are a built-in, fully managed DeployCloud feature; Kamal deploys a single target defined in deploy.yml. With DeployCloud, each branch gets its own live URL, provisioned and cleaned up automatically.
