React Flow

React Flow is an open‑source, MIT‑licensed React component library for building node‑based interfaces such as workflow editors, no‑code apps, and data pipelines. It provides drag‑and‑drop, zoom, pan, multi‑select and a plugin ecosystem (background, minimap, controls, node toolbar, resizer). Custom nodes are regular React components, so you can style them with Tailwind, CSS, or any approach, delivering a high‑performance, flexible diagramming solution.
