Kubero
Self-hosted Kubernetes PaaS for developers without specialized knowledge
Kubero is a self-hosted Platform as a Service that deploys applications on Kubernetes without requiring specialized knowledge. Deploy from containers or source code with GitOps workflows.
Overview
What is Kubero?
Kubero is a self-hosted Platform as a Service (PaaS) designed to democratize Kubernetes deployments. It enables developers to deploy applications on Kubernetes clusters without specialized container orchestration knowledge, following 12-factor app principles.
Core Capabilities
Kubero supports deployment from existing Docker containers or directly from source code across multiple languages including Go, Python, Node.js, PHP, Ruby, and Rust. The platform provides GitOps-driven CI/CD pipelines with up to four staging environments, automatic review apps for pull requests, and seamless redeployment triggers on branch or tag pushes.
The platform ships with 160+ application templates for popular software like WordPress, Grafana, and Bitwarden, plus integrated add-ons for PostgreSQL, Redis, MongoDB, and more. Built-in features include vulnerability scanning, application logs, metrics monitoring, scheduled tasks, and notifications via Discord, Slack, or webhooks.
Architecture & Deployment
Kubero runs Kubernetes-native with two containers (kubero-ui and Operator) and stores all data in Kubernetes etcd without requiring external databases. It supports major Git providers (GitHub, GitLab, Bitbucket, Gitea, Gogs) and can be installed on existing clusters or new ones via the Kubero CLI on GKE, Scaleway, DigitalOcean, Linode, or Kind for local development.
Highlights
GitOps CI/CD pipelines with automatic review apps and up to 4 staging environments
160+ application templates and integrated add-ons (PostgreSQL, Redis, MongoDB, RabbitMQ)
Deploy from Docker containers or source code across 10+ languages and frameworks
Kubernetes-native architecture with no external database dependencies
Pros
- No specialized Kubernetes knowledge required for developers
- Comprehensive GitOps workflow with automatic review apps and multi-stage pipelines
- Extensive add-on ecosystem and 160+ ready-to-use application templates
- Built-in monitoring, vulnerability scanning, and notification integrations
Considerations
- Requires existing Kubernetes cluster or infrastructure setup
- Built-in add-ons are not High Availability ready by default
- Bitnami add-ons deprecated due to upstream repository changes
- GPL-3.0 license may restrict commercial use cases

Fit guide
Great for
- Development teams wanting Heroku-like simplicity on their own Kubernetes infrastructure
- Organizations requiring self-hosted PaaS with full control over deployment environments
- Teams needing GitOps workflows with automatic review apps and multi-stage pipelines
- Projects requiring multi-tenancy and SSO authentication capabilities
Not ideal when
- Teams without access to Kubernetes clusters or cloud infrastructure
- Production workloads requiring High Availability add-ons out of the box
- Organizations needing commercial support and enterprise SLAs
- Simple single-container deployments where full PaaS features are unnecessary
How teams use it
Multi-Stage Application Deployment
Deploy applications through review, test, staging, and production environments with automatic promotion and rollback capabilities
Automated Review Apps for Pull Requests
Automatically spin up isolated environments for each pull request and clean them up when merged or closed
Rapid Template-Based Deployments
Launch WordPress, Grafana, or 160+ other applications instantly using pre-configured templates with integrated add-ons
Self-Hosted PaaS for Development Teams
Provide developers Heroku-like deployment experience on internal Kubernetes infrastructure with full data sovereignty

Frequently asked questions
Does Kubero require Kubernetes expertise to use?
No. Kubero abstracts Kubernetes complexity, allowing developers to deploy applications without specialized container orchestration knowledge. The CLI can even provision clusters on supported cloud providers.
What Git providers does Kubero support?
Kubero integrates with GitHub, GitLab, Bitbucket, Gitea, Gogs, and Forgejo for both hosted and self-hosted repositories.
Are the built-in add-ons production-ready?
Built-in add-ons (PostgreSQL, Redis, MongoDB, etc.) are designed for quick starts but are not High Availability ready. For production, consider external HA-ready add-ons like Crunchy Postgres Cluster or Redis Cluster.
Can I deploy existing Docker containers or only from source?
Both. Kubero supports deploying pre-built Docker containers directly or building from source code across multiple languages including Go, Python, Node.js, PHP, Ruby, and Rust.
Where is application data stored?
All Kubero configuration data is stored in Kubernetes etcd. No external database is required, keeping the architecture simple and Kubernetes-native.
