  Konflux

  Infrastructure and cloudNew in 2026

  Konflux is an open source, opinionated Kubernetes-native software factory built on Tekton, focused on software supply chain security. It provides an end-to-end pipeline: hermetic builds from source, cryptographic signing, provenance attestation, vulnerability scanning, policy verification, and release automation. Konflux integrates with the broader supply chain security ecosystem (Sigstore, SLSA, Conforma) and is built by a welcoming community that values collaboration, transparency, and mentorship. Contributors work with cutting-edge cloud-native technologies and help shape how we solve one of the most critical challenges in modern software delivery.

  Kubeflow

  Infrastructure and cloud

  Our goal is to streamline the process of scaling and deploying machine learning (ML) models to production by leveraging Kubernetes' strengths: <br /><br /> - Seamless deployments: Effortless, repeatable, and portable deployments across diverse infrastructure, allowing you to experiment on local machines and then seamlessly transition to on-premises clusters or the cloud. <br /><br /> - Microservice management: Efficient deployment and management of loosely-coupled microservices for building modular and scalable ML pipelines. <br /><br /> - Dynamic scaling: Automated scaling based on demand, ensuring optimal resource utilization. <br /><br /> User-centric design: Recognizing the diverse tool preferences within the ML community, we prioritize user customization (within reasonable boundaries). Our system takes care of the repetitive tasks, freeing users to focus on the core ML challenges. <br /><br /> Starting focused, expanding rapidly: While we initially focused on specific technologies, we actively collaborate with various projects to integrate additional tools and broaden our reach. <br /><br /> Our vision: A future where simple manifests empower you to utilize a user-friendly ML stack anywhere Kubernetes runs, with self-configuration capabilities based on the deployment environment.
