What Fluidd is

Fluidd is a free, self-hosted web interface for managing Klipper-based 3D printers. It provides printer controls, print monitoring, file tools, and status information through a responsive interface for desktop, tablet, and mobile screens. One installation can manage multiple printers. Users can customize dashboard layouts, select built-in color themes, and use dark mode. Printing features include a multi-tool G-code viewer with object exclusion, print history with statistics and re-printing, and slicer thumbnail previews. Monitoring tools include thermal charts and presets, multiple webcam support, and a diagnostics dashboard with custom metrics. The file manager supports uploads, search, previews, and drag-and-drop; a file editor includes syntax highlighting and macro organization controls. Dedicated integrations include Happy Hare, AFC, Beacon, Cartographer/Scanner, Kalico, Spoolman, Obico, and OctoEverywhere. Fluidd requires Klipper firmware and Moonraker, the API server that connects Klipper to web interfaces. The maker recommends KIAUH for installation; Docker or a release ZIP served from an HTTP server are also options. FluiddPI is not actively maintained and is not recommended.
