OctoPrint vs. Klipper

A comparison between OctoPrint and Klipper.

OctoPrint and Klipper

In the world of 3D printing, the software you choose can make a big difference in how well your printer works. OctoPrint and Klipper are the two most popular options, each with its own unique features. OctoPrint lets you control and monitor your 3D printer remotely using a web interface. On the other hand, Klipper takes a different approach by replacing the printer's built-in software to improve performance. Today we will compare OctoPrint and Klipper, looking at what each does well and where they might fall short. Whether you're focused on ease of use or want to boost your printer's capabilities, understanding these two options is key for 3D printing enthusiasts.


OctoPrint: OctoPrint is primarily a 3D printer management tool that provides a web interface for controlling and monitoring 3D printers remotely. OctoPrint allows users to start and stop prints, monitor print progress, and control printer settings through a web browser.

Klipper: Klipper is a firmware replacement software. Klipper takes over the low-level control of the printer, running on a Raspberry Pi or similar microcontroller. It offloads complex processing tasks from the printer’s onboard firmware, leading to potential performance improvements.

Control Architecture

OctoPrint: OctoPrint relies on the existing firmware on the 3D printer. It sends commands to the printer through USB or serial connection, and the printer’s firmware interprets and executes those commands.

Klipper: Klipper replaces the firmware on the printer’s microcontroller with its own firmware. Klipper runs on a separate microcontroller (usually a Raspberry Pi), allowing it to handle complex calculations and leave the printer’s microcontroller to handle real-time motion control.


OctoPrint: OctoPrint’s performance is limited by the capabilities of the printer’s onboard microcontroller and firmware.

Klipper: Can potentially provide better performance, especially on printers with less powerful onboard microcontrollers, as the Raspberry Pi running Klipper can handle advanced calculations.


OctoPrint: OctoPrint is compatible with a wide range of 3D printers and firmware types. It is a versatile solution that can be used with various setups.

Klipper: Compatible with many 3D printers, but it requires flashing new firmware onto the printer’s microcontroller. Some users find this process more involved and difficult compared to using OctoPrint.

User Interface

OctoPrint: OctoPrint provides a user-friendly web interface for managing and monitoring prints. It includes features like webcam support, plugin support, and a plugin ecosystem for extending functionality.

Klipper: Does not have a standalone user interface. Users interact with Klipper through configuration files. It relies on external tools for monitoring and controlling prints, such as OctoPrint.

Which Should I Choose?

Ultimately, the choice between OctoPrint and Klipper comes down to personal preference. OctoPrint is a powerful management tool with a focus on remote control and monitoring, and is generally seen as a more beginner friendly software. Klipper is a firmware replacement software designed to optimize the low-level control of 3D printers for better performance. Consider these factors when deciding which software is best for you.
