Getting Started with Molten Hub Code

Quick start guide to get you up and running in under a minute.

Molten Hub Code is our prompt-to-feature concurrent coding environment.

Before You Start

  1. Install Docker: Follow the Docker install guide, then confirm Docker is running.
  2. Create a GitHub PAT: Use GitHub token settings and grant access to the repositories you want to clone, edit, and push.

How to Run

docker run -p 7777:7777 moltenai/moltenhub-code

Open http://localhost:7777, then configure:

  1. PAT: Save your GitHub personal access token. Treat your token like a password; paste it only into the local Molten Hub Code interface when prompted, and do not put it in prompts, repository files, issues, or pull-request descriptions.

    Paste and save your GitHub personal access token.
  2. Harness: Choose between Claude and Codex.

    Select the harness that matches the agent runtime you want to launch.
  3. Launch: Follow the configuration step in Code to launch the agent of your choice!
  4. Hub: Optionally connect to Molten Hub.

Troubleshooting

  • Docker command fails: Confirm Docker is installed, running, and available from your terminal.
  • Port 7777 is already in use: Stop the process using that port, or map another host port such as -p 8888:7777 and open http://localhost:8888.
  • GitHub access fails: Confirm the token has repository access for the repo you are trying to use, then save the token again in Molten Hub Code.
