K3s vs Kubeli

K3s is a certified, lightweight Kubernetes distribution for IoT and edge computing. It runs self-hosted on Linux and is released for x86_64, ARMv7, and ARM64. The distribution arrives as one binary or a minimal container image; the site describes the binary as under 70 MB, while documentation says under 100 MB. Documented uses include edge systems, homelabs, IoT, continuous integration, development, ARM single-board computers, air-gapped environments, and embedded Kubernetes. SQLite is the default datastore, with etcd, MySQL, and Postgres available. K3s packages containerd or cri-dockerd, Flannel, CoreDNS, Traefik, ServiceLB, Kube-router, local-path-provisioner, and Spegel. High-availability deployments can use embedded storage or external MySQL, PostgreSQL, or etcd. Air-gapped installation supports private registries, manually deployed images, or an embedded registry mirror. Security guidance includes hardening and CIS self-assessment material. Automated Kubernetes-native upgrades use Rancher’s system-upgrade-controller.

Kubeli is a native desktop application for managing Kubernetes clusters on macOS, Windows, and Linux. It connects to multiple clusters simultaneously and supports one-click context switching. A topology view nests namespaces, deployments, and pods so cluster structure can be inspected graphically. Pod logs stream with search, timestamps, and error highlighting, and can be passed to a locally running AI assistant. Kubeli maps local ports to pods or services and can open forwarded ports in a browser. Its listed AI integrations include Claude Code, Codex, OpenCode, and Droid. An included MCP server lets VS Code, Cursor, or Claude Code query cluster state. HTTP, HTTPS, and SOCKS5 proxy support addresses clusters behind corporate firewalls. The site lists macOS 10.15+, Windows 10/11, and Linux x64 downloads. Kubeli is free and MIT open source, requires no account or telemetry, and says it does not transfer information to other networked systems unless requested. Support is provided through GitHub Discussions, feature requests, and bug reports.
