Top SANDBOX GitHub Repositories & Tools (2026)

Isolated VM environment for running Claude Code and Codex

Omnigent is an open-source AI agent framework and meta-harness: orchestrate Claude Code, Codex, Cursor, Pi, and custom agents — swap harnesses without rewriting, enforce policies and sandboxing, and collaborate in real time from any device.

The automation tower defense RTS

Linux sandboxing that doesn't get in your way

Secure, Fast, and Extensible Sandbox runtime for AI agents.

Secure and fast microVMs for serverless computing.

The Open Framework for Building Agents

Engineering Software Factory - open source, self-hosted, local AI first

A sandbox for the third-party APIs you depend on. Built from the provider's spec, it fails on purpose, and it replays the exact failure production hit.

agent runtime security - zero trust, zero setup, zero latency.

The World's First Virtual Terminal for AI Agents

lnwjud — local AI-agent runtime & MCP gateway

Open-source agent runtime — SSH-native isolation, eBPF egress policy, Kubernetes + LXC backends, GPU passthrough, MCP-native CLI

AI pair programming in your terminal — one static binary, sub-ms startup, any model

🧱 easy fast branchable microVM runtime and library for any workload

Chat, specs, tasks, and code. An autonomous engineering platform. Full autonomy when you trust it. Full control when you don't.

The runtime behind every E2B stack: Cloud, Enterprise, and your own machine.

Run coding agents like infrastructure, not terminal sessions. Warren manages isolation, lifecycle, spend, recovery, and Git delivery on compute you control.
