Kubero

With over 4,300 GitHub stars and a v3 release adding built-in user management, team views, and multi-language support, Kubero has established itself as the most feature-complete open-source Heroku alternative running natively on Kubernetes. The platform operates as a Kubernetes operator with two containers — kubero-ui and the operator — storing all state in etcd without an external database. Developers push code via Git integration with GitHub, GitLab, Bitea, or Gitea, and Kubero automatically builds using Buildpacks, Nixpacks, Runpacks, or Dockerfiles, then deploys to the configured domain with SSL via cert-manager. CI/CD pipelines support up to four staging environments — review, test, staging, and production — with per-stage environment variable isolation and ephemeral review apps that spin up on pull request open and tear down on close. The template catalog includes over 170 pre-configured applications like WordPress, Grafana, and PostgreSQL deployable in one click, while managed add-ons provide highly available PostgreSQL, Redis, MySQL, Kafka, CouchDB, Elasticsearch, and MongoDB alongside your applications. Security features include Trivy vulnerability scanning, GitHub and OAuth2 single sign-on, basic auth, and a role-based permission system with API tokens. The NestJS backend with Vue.js and Vuetify frontend provides application metrics, real-time logs, a built-in web console for container access, scheduled cronjob management, and deployment notifications via Discord, Slack, or webhooks. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Benefits

  • Heroku Workflow on Kubernetes
  • Git-push deployments with automatic builds via Buildpacks, Nixpacks, or Dockerfiles eliminate YAML manifests and Helm chart complexity while preserving full Kubernetes scalability underneath.
  • Ephemeral Review App Automation
  • Pull requests automatically spawn isolated review environments with dedicated URLs and tear down on merge or close, enabling safe testing without manual staging configuration.
  • 170+ One-Click Application Templates
  • Pre-configured templates deploy popular applications like WordPress, Grafana, PostgreSQL, and Redis with managed highly available add-ons alongside your custom applications instantly.
  • Integrated Security and Scanning
  • Built-in Trivy vulnerability scanning, GitHub and OAuth2 single sign-on, role-based access control with API tokens, and basic auth configuration protect applications at every layer.

Features

  • Multi-Stage CI/CD Pipelines
  • Create unlimited pipelines with up to four staging environments — review, test, staging, production — each with isolated environment variables and automatic redeployment triggers.
  • GitOps Review Apps
  • Ephemeral environments spawn automatically on pull request creation with dedicated domains and tear down on merge, supporting GitHub, GitLab, Bitea, and Gitea repositories.
  • Managed Add-On Database Clusters
  • Deploy highly available PostgreSQL, Redis, MySQL, Kafka, CouchDB, Elasticsearch, and MongoDB instances alongside applications with automated provisioning and configuration.
  • Web Console and Live Logs
  • Built-in container web console provides direct shell access while real-time log streaming, application metrics, and deployment notifications flow to Discord, Slack, or webhooks.
  • Trivy Vulnerability Scanning
  • Scheduled or triggered security scans detect vulnerabilities in running application containers with aggregated results visible directly in the Kubero web interface.
