mrmd 0.9.4

Collaborative markdown notebooks - edit and run code together

mrmd

Collaborative markdown notebooks - edit and run code together.

Quick Start

# Run directly with uvx (no install needed)
uvx mrmd

# Or install and run
pip install mrmd
mrmd

What it does

mrmd opens a collaborative markdown editor in your browser. You can:

• Write markdown with live preview
• Add executable code blocks (Python, JavaScript, etc.)
• Collaborate in real-time with others
• Run code and see output inline

Usage

# Open editor in current project
mrmd

# Use custom docs directory
mrmd --docs ./notes

# Use custom port
mrmd --port 3000

# Don't open browser automatically
mrmd --no-browser

How it works

mrmd automatically detects your project root by looking for common markers:

• .git - Git repository
• .venv - Python virtual environment
• pyproject.toml - Python project
• package.json - Node.js project
• etc.

It then:

1. Starts a sync server for real-time collaboration (Yjs/CRDT)
2. Starts a Python runtime for code execution
3. Serves the editor UI
4. Opens your browser

Documents are saved to the docs/ directory in your project (or notebooks/, notes/ if they exist).

Development
