DGit: Version Control for Design Files

DGit is a version control system built for large design files like PSD, AI, and Sketch. Unlike traditional systems that struggle with binary files, DGit reads the internal structure of files to track changes efficiently.

What DGit Does

DGit solves the storage problem of design files through smart compression and layer-level change detection.

Key Features:

• Smart compression: Picks the right method based on file size
  • Files under 100MB: Binary delta compression (saves space)
  • Files over 100MB: Fast LZ4 snapshots (saves time)
• Layer tracking: Analyzes PSD layers to find what changed
• Fast and efficient: Compresses files quickly while saving disk space

Two Ways to Use DGit

CLI (Command Line)

Simple commands for version control:

dgit init           # Start a project
dgit add .          # Add files
dgit commit "msg"   # Save version
dgit status         # Check changes
dgit log            # View history

GUI (Visual Interface)

Easy-to-use interface with:

• Drag and drop files
• Visual commit history
• Project management

Installation

From Releases: Download the latest version from GitHub Releases.

From Source:

CLI (Core Engine)

# Build DGit
go build -o dgit

# Or run directly
go run main.go --help

GUI (Electron App)

The GUI requires Node.js. Commands must be run from the /ui directory.

# Navigate to the UI directory
cd ui

# Install dependencies
npm install

# Start the application
npm start

Quick Start

# Start a new repository
dgit init

# Add files and create a commit
dgit add .
dgit commit "Initial design"

# Check what changed
dgit status

# View commit history
dgit log

# See details of a specific version
dgit show v1

Supported Files

Full Support: Analyzes metadata and tracks layers
Basic Support: Tracks file versions only

How It Works

DGit stores your files in a clean structure:

.dgit/
├── snapshots/      # LZ4 compressed files
├── deltas/         # Binary delta files
├── commits/        # Commit information (JSON)
├── staging/        # Files ready to commit
├── temp/           # Temporary files
├── config          # Settings
└── HEAD            # Current version
