Sailbox vs CapRover
CapRover is one of the original self-hosted PaaS tools built on Docker Swarm. Sailbox represents the next generation — powered by Kubernetes.
CapRover pioneered easy self-hosted app deployment with its one-click apps and simple UI. Sailbox builds on this idea with a modern stack: Kubernetes (K3s) for orchestration, Kaniko for secure in-cluster builds, autoscaling, health probes, two-factor authentication, and automated database backups.

What sets Sailbox apart
Real Kubernetes, not a wrapper
Sailbox runs K3s — a CNCF-certified Kubernetes distribution. Your apps run as real Deployments with kubectl access. No lock-in, no abstraction layer.
In-cluster builds with Kaniko
No Docker socket exposure. Sailbox builds container images inside the cluster using Kaniko, which is more secure and doesn't require privileged containers.
Production features built in
Autoscaling (HPA), health probes, rolling deploys, RBAC, 2FA, automated database backups — everything you need for production, included from day one.
Frequently asked questions
Why switch from CapRover to Sailbox?
CapRover uses Docker Swarm, which lacks autoscaling, health probes, and native CronJob support. If you need production features like HPA, rolling deploys with readiness checks, or RBAC with 2FA, Sailbox provides these natively through Kubernetes.
Does Sailbox have one-click apps like CapRover?
Sailbox includes one-click deployment for PostgreSQL, MySQL, MariaDB, Redis, and MongoDB. For applications, it focuses on git-push and Docker image deployment. Any Docker image can be deployed as an application.
Is Sailbox harder to set up than CapRover?
No. Sailbox installs with a single curl command: curl -sSL https://get.sailbox.dev | sudo sh. It runs on any Linux server with 2GB RAM. The setup experience is comparable to CapRover's.
