Sandboxes and guardrails for agents

I want to pick an open-source project for keeping agents from doing damage: sandboxes, permission checks and secret masking. Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - E2B: E2B lets developers run code written by AI in isolated, disposable sandboxes in the cloud, so it cannot touch other systems. It is aimed at programmers and teams building AI tools. [Advanced setup; runs on a server you set up; replaces partly; Apache-2.0; https://github.com/e2b-dev/E2B] - microsandbox: Microsandbox runs untrusted programs, such as AI agents, user code and automation tasks, inside small virtual machines on your own computer so they cannot harm the rest of the system. It is aimed at developers who build agents or tools that need to run code safely. [Advanced setup; Windows · Mac · Linux; replaces partly; Apache-2.0; https://github.com/microsandbox/microsandbox] - container-use: Container Use runs AI coding assistants inside separate containers, so each agent works in its own isolated copy of a project and its changes stay on their own git branch. It is aimed at software developers who use AI coding agents. [Advanced setup; Windows · Mac · Linux; replaces partly; Apache-2.0; https://github.com/dagger/container-use] - sandbox-runtime: Sandbox Runtime (srt) is a command-line tool that limits which files and websites a program can reach, by applying restrictions built into the operating system. It is for developers who want to run AI agents, local tool servers, or other programs with less access to their computer. [Advanced setup; Windows · Mac · Linux; replaces partly; Apache-2.0; https://github.com/anthropic-experimental/sandbox-runtime] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/agent-safety.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/agent-safety.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
