OctoPrint is the snappy, free, open-source web interface for remote control and monitoring of consumer 3D printers.
🚀 Overview
OctoPrint turns everyday devices like a Raspberry Pi into a powerful 3D printer web interface, enabling full remote control and monitoring of print jobs via any web browser.
It solves the lack of remote access and advanced features in most consumer 3D printers, preventing babysitting prints and enabling mobile oversight. Built for 3D printing enthusiasts, hobbyists, makers, and professionals who demand reliability, extensibility, and community-driven development. Created by Gina Häußge to deliver a snappy, plugin-powered alternative to clunky proprietary software.
✨ Key Features
- Full remote control and monitoring (webcam feed, print progress, GCODE visualizer, temperature control, axis movement, extrusion).
- Print job management: upload, slice, start/pause/stop/resume anytime.
- Powerful plugin ecosystem (timelapse, bed leveling, themes, firmware updates, printer-specific support).
- Access controls, system commands, event triggers, timelapse videos.
🛠 Tech Stack
- Backend: Python, Flask
- Frontend: JavaScript, Jinja2 templating, Less CSS
- Other: G-code processing
- Auth: Built-in user access controls
- Hosting: Self-hosted (Raspberry Pi via OctoPi image, Docker, etc.)
👥 Who Is This For?
This project is useful for:
- 3D printing hobbyists who want remote monitoring to avoid print failures
- Makers building custom plugins and extensions
- Teams managing print farms with advanced controls
