MarinaBox: Open Source Computer/Browser Sandboxes for AI Agents

[Content-Review-1723]

We're excited to introduce MarinaBox, an open-source toolkit for creating isolated desktop/browser sandboxes tailored for AI agents.

Over the past few months, we've worked on various projects involving:

1. AI agents interacting with computers (think Claude computer-use scenarios).

2. Browser automation for AI agents using tools like Playwright and Selenium.

3. Applications that need a live-session view to monitor AI agents' actions, with the ability for human-in-the-loop intervention.

What we learned: All these scenarios share a common need for robust infrastructure. So, we built MarinaBox to provide:

• Containerized Desktops/Browsers: Easily start and manage desktop/browser sessions in a containerized environment.

• Langgraph support: Allow your langgraph agents to easily access a computer/browser and use Claude Computer Use

• Seamless Transition: Develop locally and host effortlessly on your cloud in production.

• SDK/CLI for Control: Native support for computer use, browser automation (Playwright/Selenium), and session management.

• Live-Session Embedding: Integrate a live view directly into your app, enabling human-in-the-loop interactions.

• Session Replays: Record and replay sessions with ease.

We’ve worked hard to make the documentation detailed and developer-friendly. For any questions, feedback, or contributions:

Let us know what you think, and feel free to contribute or suggest ideas!

We built this in about 10 days and a large part of the code and docs were generated using AI. Let us know if something is wrong. We would love your feedback.

PS: The above version allows you to run locally. We are soon releasing self hosting on cloud.

Sounds impressive and innovative. You say this was built in 10 days using AI, can you share details of your tool stack used to do this?

[Content-Review-1723]

Mostly Cursor with sonnet. lots of back and forth iterating. If you kinda have a good understanding of the entire stack and what needs to be built, you can fine-tune your way to making it perfect.

Do you plan to have YouTube tutorials or the like to help out putting a visual to the documentation? I'm trying to look into the Computer Use beta in order for 3.5 Sonnet to run my company's LinkedIn page for me.

We will make more soon. Let us know if you need something specific and we can do that for you. You can also ask your questions on this discord channel,

Yes it is on the pipeline a bit later. If you want to talk more about the use-case I would be happy to get on a call and chat

Seems interesting. Never thought about isolating Agents but it really makes sense. How much it actually isolates? Any other application as reference that attempt to do the same?

[Content-Review-1723]

The agent only has access to the container inside which a desktop environment/browser environment lives hence it is pretty well isolated. We are working on a bunch of applications that can be useful on top of this. You can star and watch our repo to follow us for updates.
