Containarium

Active·★ 310·Apache-2.0·Updated 2026-10-22
★ Hidden Gem

Containarium is an open-source, self-hostable, agent-native sandbox that provides persistent, isolated, and real Linux environments for AI agents to build, install, deploy, and verify their work. It runs as a single-host platform using LXC containers, exposing its administration via MCP and CLI, and includes an in-container MCP server for direct shell execution and file operations.

Containarium sits in the Dev Tooling category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Agent-native sandboxes for AI agents (Cursor, Claude Code, OpenCode) with persistent state and real Linux environments.. A representative use case is AI-agent sandboxes for development, testing, and deployment.. The listed license is Apache-2.0. GitHub stars are currently 310. Relevant tags include AI Agents, Sandbox.
