A free, open source LaTeX editor with real-time preview capabilities. Think Overleaf, but without compilation limits, completely free, and self-hostable.

• Real-time Preview: See your LaTeX document rendered as you type (optional auto-compile)
• No Compilation Limits: Compile as many documents as you want, whenever you want
• Multi-file Projects: Upload ZIP files with multiple .tex files, images, and fonts
• Syntax Highlighting: Full LaTeX syntax highlighting for easier editing
• File Management: Add, rename, and delete files directly in the browser
• Free & Open Source: No paywalls, no subscriptions, no restrictions
• Self-Hostable: Run it locally with Docker or deploy to your own server
• Client-side Processing: All processing happens in your browser

# Clone the repository
git clone https://github.com/mbianchidev/latex-editor.git
cd latex-editor

# Start with Docker Compose
docker compose up -d

# Open http://localhost in your browser

# Serve the frontend folder with any static server
cd frontend
python3 -m http.server 8080
# Open http://localhost:8080

1. Upload a ZIP file containing your LaTeX project
2. Files starting with ._ or in __MACOSX folders are automatically filtered
3. Use the file tree to navigate between files
4. Right-click files for rename/delete options
5. The main .tex file is auto-detected (or set manually)

The "Auto" checkbox controls automatic compilation:

• Off (default): Manual compile only - click ▶ or press Ctrl+Enter
• On: Auto-compile 3 seconds after you stop typing
