Hey everyone,

I'm excited to announce that Kubero v3.0.0 is officially out! 🎉

This release marks a major internal overhaul — we’ve refactored the entire backend and migrated from Express.js to NestJS. All features from v2 have been migrated and remain fully available.

---

Why the switch to NestJS?​

Kubero was initially built as a Proof of Concept during Heroku's major outage in 2022. While Express served us well in v1 and v2, NestJS brings significant advantages that will help Kubero evolve into a more scalable, secure, and maintainable platform:

• Modular Architecture
  NestJS encourages a well-structured, modular codebase, making it easier to manage features and scale. This also lowers the barrier for contributors to dive in and build with us.

• Improved Security
  Kubero now uses JWT tokens for authentication, replacing the older session-based method. This improves both security and maintainability.

• Simplified API
  The API has been redesigned to be more intuitive, with clearer endpoints and improved documentation.

• Better Logging and Error Handling
  NestJS provides enhanced support for logging and centralized error handling out of the box.

• Thriving Ecosystem
  The NestJS ecosystem, with its integration libraries and support, helps us provide powerful new features faster and more efficiently.

• More Tests = More Stability
  We’ve added extensive Jest tests — the new codebase has 86% test coverage, ensuring a more stable and reliable experience.

This update lays the groundwork for upcoming features like role-based access control and team structures.

What about the frontend?​

The frontend remains unchanged in this release. Kubero's UI is still the same clean, intuitive interface you're familiar with from v2. This means:

• No changes are required to your workflows or usage patterns.
• Your existing deployments, dashboards, and settings will look and behave the same.

We're continuing to maintain and refine the frontend, but our focus in v3 was on strengthening the backend foundation.

Upgrade Notes​

• In-place upgrade: Simply update the tag — all features and configurations are compatible.
• If you're using the CLI, make sure to update to version 3.0.0.
• If you're integrating Kubero’s API into your own toolchain, note that the API paths have changed. See the API documentation for details.

Kubero remains proudly open-source and community-driven. We’re still planning to donate the project to the CNCF to ensure its long-term sustainability.

Would love to hear your feedback, questions, or thoughts. Thanks for being part of the journey!

In the evolving landscape of Platform as a Service (PaaS) solutions, developers seek platforms that streamline application deployment and management. Coolify and Kubero are both open-source, self-hosted PaaS platforms catering to this need. While both offer robust features, Kubero distinguishes itself with several advanced capabilities that provide a competitive edge.

Coolify​

Coolify positions itself as an open-source alternative to platforms like Heroku, Netlify, and Vercel. It supports a wide range of programming languages and frameworks, enabling developers to deploy static websites, APIs, backends, databases, and various services. Deployment is flexible, accommodating any server with SSH access, including personal servers, VPS, Raspberry Pi, and cloud providers like AWS and DigitalOcean. Key features include push-to-deploy via Git integration, automatic SSL certificate management, real-time terminal access, and monitoring capabilities.

Kubero​

Kubero is a PaaS tailored specifically for Kubernetes environments, emphasizing simplicity and scalability for deploying 12-factor applications. It supports multiple languages and frameworks through buildpacks, including PHP, Ruby, Golang, Rust, Node.js, and Deno. Kubero offers seamless GitOps integration with various repositories, built-in CI/CD pipelines, and a comprehensive CLI for cluster management. Notably, it provides features like autoscaling, vulnerability scanning with Trivy, a web console for application maintenance, and customizable notifications.

Key Differences​

Infrastructure​

Kubero is inherently designed for Kubernetes, leveraging its orchestration capabilities for scalability and resilience. In contrast, Coolify currently lacks native Kubernetes support, which limit scalability for enterprise applications.

Autoscaling and Resource Management​

Kubero's autoscaling features allow applications to scale horizontally and vertically based on demand, optimizing resource utilization. Additionally, it offers "sleeping containers" that pause inactive pods to conserve resources. Coolify does not provide comparable autoscaling capabilities.

Metrics and Monitoring​

Kubero excels in providing detailed application-level metrics, giving developers real-time insights into the performance and behavior of their deployed apps. This includes data such as response times, request counts, and resource usage specific to applications. In contrast, Coolify limits its monitoring capabilities to system-level metrics, such as server resource utilization (CPU, RAM, and disk). For teams requiring deeper application performance insights to optimize and troubleshoot effectively, Kubero stands out as the superior choice.

Security and Compliance​

Security Measures: With integrated vulnerability scanning using Trivy, Kubero proactively identifies security issues in images and repositories, enhancing application security. Coolify lacks a built-in vulnerability scanning feature.

Enterprise grade Add-ons​

Both Coolify and Kubero provide a variety of addons, allowing developers to integrate essential services such as databases and caching systems. However, Kubero goes a step further by deploying these addons as highly available clusters, ensuring redundancy and resilience. For example, services like Redis-Cluster, PostgreSQL, and Elasticsearch can be deployed with built-in high availability, making Kubero a more reliable choice for mission-critical applications. In contrast, Coolify's one-click service deployments are limited to standalone instances, which may not meet the demands of enterprise-level applications.

Community and Ecosystem​

Coolify boasts a significantly larger and more active community, offering developers access to a wealth of shared knowledge, quick responses to questions, and collaborative support. This vibrant community can be a valuable resource, especially for smaller teams or individual developers.

However, Kubero leverages the vast and well-established Kubernetes ecosystem, which provides unparalleled flexibility, scalability, and a wealth of tools, plugins, and integrations. By being Kubernetes-native, Kubero allows developers to tap into a broader ecosystem of expertise and innovation that aligns with industry standards for cloud-native development. While Coolify’s community is an advantage, Kubero’s alignment with Kubernetes ensures it benefits from a much larger and continually evolving ecosystem.
