What is MoltShell? ​

MoltShell is a browser-based terminal that gives you a dedicated Linux virtual machine. Instead of configuring a local development environment or spinning up a cloud server manually, you open a browser tab and start working.

How it works ​

When you sign up, MoltShell provisions a GCP Compute Engine VM just for you. You access it through a terminal interface in your browser that connects over WebSocket. The VM runs Ubuntu 22.04 with common development tools pre-installed.

The terminal is not a container or a shared environment. It is a full virtual machine with:

  • 2 vCPUs and 4GB of RAM
  • Passwordless sudo (full root access)
  • Persistent storage that survives restarts
  • Your own home directory at /home/moltshell

Key differences from other tools ​

vs. a local terminal: No setup required. Works on any device with a browser, including tablets and phones. Your environment is the same regardless of which machine you use.

vs. a VPS: No server management. MoltShell handles provisioning, networking, and lifecycle automatically. Your VM suspends when idle to save resources and resumes when you come back.

vs. Codespaces/Gitpod: Not tied to a specific repository. Your VM is a general-purpose Linux machine where you can work on anything. Install whatever tools you need.

What's included ​

Every VM comes with:

  • Ubuntu 22.04 LTS
  • Node.js 22 (LTS)
  • Python 3 with pip
  • tmux for session persistence
  • build-essential (gcc, g++, make)
  • git, curl, wget, and standard CLI tools

You can install additional packages with sudo apt install or any other package manager.

Free during early access ​

MoltShell is free to use during the early access period. Each user gets one VM that auto-suspends after 60 minutes of inactivity to conserve resources.
