What is it?
ComfyUI_frontend is the official browser-based user interface for ComfyUI, a node-graph tool for building and running generative AI pipelines. Users wire together nodes on a canvas to define a workflow, then queue it for execution against the ComfyUI backend.
Beyond the canvas, the front-end provides a node search box with fuzzy matching, a queue and history sidebar, a node library sidebar, a mask editor, and an integrated server terminal toggled with Ctrl + `. It also includes native interface translation covering 14 languages, customizable keybindings, and group and link editing tools in the Litegraph canvas.
The project exposes extension APIs for custom commands, keybindings, topbar menu items, sidebar tabs, bottom panel tabs, settings, toasts, and selection toolbox buttons. Nightly builds can be loaded into a ComfyUI install with a launch argument.
