Everything you need to run production workloads

Not another Docker Compose wrapper. Sailbox uses real Kubernetes — so you get rolling deploys, autoscaling, health checks, and kubectl compatibility out of the box.

Git Push to Deploy

Connect your GitHub repo and push to deploy. Sailbox builds in-cluster via Kaniko — no Docker socket exposure, no external build servers.

  • GitHub App integration
  • In-cluster Kaniko builds
  • Rolling deploys & one-click rollback

Managed Databases

One-click PostgreSQL, MySQL, MariaDB, Redis, and MongoDB. Connection strings, external access via NodePort, and automated S3 backups with scheduling.

  • 5 database engines
  • Automated S3 backups
  • External NodePort access

Autoscaling & HPA

Kubernetes Horizontal Pod Autoscaler built right in. Set CPU or memory thresholds and let Sailbox scale your workloads automatically.

  • CPU & memory based scaling
  • Configurable thresholds
  • Real Kubernetes HPA

Alerts & Monitoring

CPU, memory, disk, node health, and pod event alerts. Real-time log streaming and a web terminal for debugging running containers.

  • Resource & event alerts
  • Real-time log streaming
  • Web terminal access

Team & Security

Owner, Admin, Member roles with project-level permissions. Two-factor authentication via TOTP. Automatic TLS certificates for custom domains.

  • RBAC with project scoping
  • Two-factor authentication
  • Auto TLS via Let's Encrypt

Cron Jobs

Native Kubernetes CronJobs managed through the UI. Set schedules, trigger manually, view run history and real-time logs.

  • Native K8s CronJobs
  • Manual trigger support
  • Run history & logs

Sailbox vs. the rest

Sailbox doesn't wrap Kubernetes — it is Kubernetes. Here's how it compares to other self-hosted platforms.
