Fluidd

Self-Hosted

Open-source Klipper-based 3D printer web interface

Overview

Fluidd is a lightweight, responsive open-source web interface for Klipper-powered 3D printers, tailored for hobbyists and small-scale manufacturing. It enables real-time printer monitoring, G-code visualization, bed leveling, file management, and macro control. Deployable via pre-built FluiddPi images for Raspberry Pi or manual Linux installation, it integrates seamlessly with Klipper’s advanced features (input shaping, pressure advance). Key highlights: webcam streaming, multi-printer support, intuitive dashboard, and customizable UI. It prioritizes performance and ease of use, making it a robust alternative to proprietary 3D printer interfaces for those valuing open-source flexibility.

Frequently Asked Questions

? Is Fluidd hard to install?

For Raspberry Pi users, FluiddPi pre-built images simplify installation—just flash to an SD card and boot. Manual Linux installs require setting up Klipper first, which needs basic command-line skills for configuration.

? Is it a good alternative to OctoPrint?

Yes! Fluidd is optimized for Klipper’s advanced features (like input shaping) that OctoPrint lacks natively. It’s lighter and more responsive, though OctoPrint supports broader firmware (Marlin, Klipper) and has more plugins.

? Is it completely free?

Absolutely! Fluidd is open-source under the GPLv3 license, with no hidden costs or premium tiers. All core features are free, and the community drives ongoing development.
