# K8E

> K8E originally stood for Kubernetes Easy Engine — a k3s-derived lightweight Kubernetes distribution — and in 2026 repositioned itself as an open-source agentic AI sandbox matrix offering a sub-100MB single binary (its build script caps the binary at 81MB), pluggable gVisor/Kata/Firecracker isolation and an E2B-compatible API.

A k3s-derived Kubernetes distribution, repositioned in 2026 as an agent sandbox matrix.

- **Category:** Execution Sandbox
- **License:** Apache-2.0
- **Language:** Go
- **Self-hosted:** Yes
- **Repository:** https://github.com/xiaods/k8e
- **Last verified:** 2026-10-04

> Caveat: Its lineage matters when evaluating maturity: the project began as a Kubernetes distribution, and the agent-sandbox positioning is a 2026 rebrand rather than a from-scratch agent-native design.
