Codeburn - Agent Usage

Running the CodeBurn Web Dashboard in an sbx Sandbox

Repository: https://github.com/AgentSeal/codeburn

By default, codeburn web only listens on 127.0.0.1, which makes the dashboard inaccessible from outside the sandbox. Using socat, you can forward the port to 0.0.0.0 and then expose it through sbx.

1. Start CodeBurn

codeburn web --no-open --port 4747

2. Install socat (if required)

sudo apt-get update
sudo apt-get install -y socat

3. Start the TCP Proxy

socat TCP-LISTEN:4748,bind=0.0.0.0,reuseaddr,fork TCP:127.0.0.1:4747

4. Publish the Sandbox Port

On the host machine, run:

sbx ports <sandbox-name> --publish 4747:4748

Replace <sandbox-name> with the name of your running sandbox.

5. Open the Dashboard

In your browser, navigate to:

http://127.0.0.1:4747

Notes

The additional TCP proxy is required because codeburn web currently binds only to 127.0.0.1 and does not provide an option to listen on 0.0.0.0.
