Top 19 Go platform-engineering Projects
-
vcluster
vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.
Project mention: The Ingress NGINX Migration Just Got Easier: 119 Annotations, 3 Targets, Impact Ratings | dev.to | 2026-04-28Let's walk through a complete migration on a real cluster. We'll use vCluster to spin up a Kubernetes cluster in Docker, deploy 3 services with NGINX annotations, and migrate them to Gateway API with Traefik.

Project mention: Show HN: Formae now supports Kubernetes, Helm, .tfvars and a public plugin hub | news.ycombinator.com | 2026-05-20
-
kubeplus
Kubernetes Operator for delivering SaaS-style, namespace-isolated application instances on Kubernetes
-
addon-controller
Sveltos Kubernetes add-on controller programmatically deploys add-ons and applications in tens of clusters. Support for ClusterAPI powered clusters, Helm charts, kustomize ,YAMLs. Sveltos has built-in support for multi-tenancy.
Project mention: Show HN: After 3 years, we've shipped Sveltos v1.0.0 | news.ycombinator.com | 2025-08-18 -
Project mention: Show HN: Flowctl – Self-service workflows with approvals and SSO. Single Binary | news.ycombinator.com | 2025-12-12

orloj
An orchestration runtime for multi-agent AI systems. Declare agents, tools, and policies as YAML; Orloj schedules, executes, routes, and governs them for production-grade operation.
Project mention: We tried every multi-agent framework — then built our own runtime | dev.to | 2026-04-09Website: https://orloj.dev

pacto
Pacto (/ˈpak.to/ — from Spanish: pact, agreement) is an open, OCI-distributed contract standard for cloud-native services.

Project mention: I'm building a read-only context engine for Kubernetes and AI agents | dev.to | 2026-06-15
So kctx uses explicit adapters for ecosystem-specific resources. An adapter can translate a CRD into the same core model used by the rest of the project: resource identity, compact status, related entities, relations, signals, and graph nodes or edges.
-
Globular
Globular — explicit distributed systems platform. Build, deploy, and operate services with a coherent 4-layer state model and AI that understands the system.
-
optipod
OptiPod is an open-source, Kubernetes-native operator that automatically rightsizes CPU and memory requests and limits for your workloads based on real-time and historical usage patterns.
Project mention: Show HN: Claude Code plugin for building Kubernetes CRD operators | news.ycombinator.com | 2026-02-23claude plugin install k8s@sagart-devtools
GitHub: https://github.com/Sagart-cactus/claude-k8s-plugin
Built this partly as a learning exercise in Claude Code's plugin system, and partly because I'm building a larger project where this capability was needed: OptiPod (https://github.com/Sagart-cactus/optipod), a GitOps-safe Kubernetes resource rightsizing operator. Happy to answer questions about the plugin architecture, the hook system, or the operator patterns baked into the skills.
