Fluidd

Fluidd provides a web‑based graphical interface for Klipper, the firmware that runs many 3D printers. It runs on a self‑hosted server and can be accessed from desktops, tablets, or smartphones, offering a responsive layout that adapts to different screen sizes. Users can view and edit G‑code, monitor temperatures and other sensor data in real time, and manage multiple printers from a single installation.

The interface is customizable: panels can be rearranged, built‑in color themes (including dark mode) are available, and users can organize macros, extruder and spool settings, and print history with statistics. Integrated webcam support handles MJPEG, HLS, and WebRTC streams, while a file manager allows uploads, previews, and drag‑and‑drop editing with syntax highlighting.

Fluidd is distributed under GPL‑3.0, is free of subscription fees, and includes Docker images for both privileged and unprivileged deployments. It integrates with Moonraker for device control and supports third‑party extensions such as Kalico, Happy Hare, and Obico, with full localization and automated updates for the underlying services.
