kern is a fast, rootless OCI container runtime, sandbox, and virtual resource runtime distributed as a small static binary without a daemon. It creates kernel-enforced containers from OCI images, using user, PID, mount, network, UTS, and IPC namespaces, overlay or read-only roots, a deny-by-default seccomp allowlist, and cgroup v2 limits; the `--security-profile untrusted` option applies the documented hardened bundle. It can also attach named CPU, memory, disk, and device profiles from `kern.toml` to containers, or apply resource caps directly to host processes with optional Landlock write confinement. The project supports container operations, Dockerfile builds, image pull/push and save/load, stack execution through its own or Docker Compose format, and includes Python and Node SDKs plus an MCP server for agents. Its Rust dependency tree uses libc, while image pulling delegates to system `curl` and `tar`; it runs natively on Linux, requires WSL2 on Windows, and needs a Linux virtual machine on macOS.

Kero is a cross-platform native terminal application for running coding agents and development processes on macOS, Windows, and Linux. It runs Claude Code, Codex, development servers, and test watchers in separate persistent sessions, grouping those sessions by project in a sidebar with working, waiting, idle, error, and exited states. Sessions run in the kerod daemon, so they continue after the application window closes and reopen with their panes and scrollback. Its CLI can create sessions, split panes, type into them, wait for processes, and read terminal screens. Kero can also connect to remote hosts over SSH or Tailscale, uses libghostty for terminal rendering, and is distributed under the MIT license.

Kiro is a proprietary agentic integrated development environment and command-line interface from Amazon Web Services. It supports specification-driven development, steering files, hooks, and cloud deployment, and uses Anthropic models through Amazon Bedrock.

K3s is a lightweight, certified Kubernetes distribution for production workloads in resource-constrained, remote, unattended, and IoT or edge environments. It packages Kubernetes as a single binary smaller than 70 MB, reducing installation, runtime, and update dependencies. A K3s cluster uses server and agent nodes: the server writes a kubeconfig and agents join it with the server URL and node token. K3s supports x86_64, ARMv7, and ARM64, and is distributed as a CNCF Sandbox project.

diri is a native desktop orchestrator for coding agents on macOS and Linux. It runs Claude Code, Codex, Cursor, Gemini, and ordinary shells in parallel, using separate Git worktrees or remote hosts over SSH and tmux. Each session is a real terminal with a persistent PTY managed by a background daemon, so closing or reopening the app does not terminate sessions; the daemon restores their output and state. The app displays working, needs-you, and done status, while its MCP server allows one running agent to spawn, monitor, read, and respond to another. Claude Code and Codex have first-class status detection and resume support, while Cursor and Gemini have partial support.
