Sandbox GitHub Repositories (2026) · Open Source Tools

agent-sandbox enables easy management of isolated, stateful, singleton workloads, ideal for use cases like AI agent runtimes and reinforcement learning (RL).

Generate sandboxes for C/C++ libraries automatically

Main development repository for Rigs of Rods soft-body physics simulator

Endo is a distributed secure JavaScript sandbox, based on SES

Microsoft Build Accelerator

Open-source, self-hosted AI app builder — an agent builds real apps in isolated sandboxes on your own server, each live at a preview URL. Self-host in one command. MIT.

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

a fast, rootless container runtime and sandbox with no daemon. It runs workloads, including agent tool calls and code generated by an LLM, in real containers enforced by the kernel.

Proper sandboxing for agentic coding and web browsing

Native macOS GUI for ArcBox — containers, VMs, and sandboxes at your fingertips. Open Source alternative to OrbStack.

Brig: run coding agents in a microVM sandbox - the Go cli (brig) and session daemon (brigd)

lnwjud — local AI-agent runtime & MCP gateway

Alter Ego: run Linux desktop applications under a different local user

AI agent builder with a VM at its heart. Every agent gets its own microVM sandbox to install software, run code and use the GPU in. Python, Node.js and Rust.

Give agents an operating system as a library. Runs in your existing backend – no sandboxes, VMs, or SaaS. Powered by WebAssembly & V8 isolates.

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

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.

Deploy secure local and cloud environments for developers and agents

Run your agent in a Minimal box. Ship and run software with isolation on your own computer.

A lightweight secure Self-evolution engine built in Rust, featuring a built-in native system-level sandbox, zero dependencies, and fully local execution.
