Node-RED Flow Arranger

Node-RED Flow Arranger automatically tidies up the layout of your exported Node-RED flows with a single click — no more manually dragging nodes around the canvas. HOW IT WORKS Export your flow from Node-RED as a .json file, drop it into the extension, hit "Arrange Flow", and save the result. Re-import it into Node-RED and your flow will be neatly organised with proper spacing, aligned columns, and logical left-to-right grouping. FEATURES • One-click auto-layout for any Node-RED flow JSON file • Drag-and-drop or browse to load your file • Intelligently groups nodes by wiring topology • Handles Kafka nodes, common-base nodes, and complex subgraphs • Preserves all node properties, wires, and settings — only positions are changed • Works entirely in your browser — no data is ever uploaded or sent anywhere • Supports files up to 10 MB WHO IS IT FOR Node-RED developers and IoT engineers who work with large, messy flows exported from Node-RED and want a quick way to make them readable before sharing, reviewing, or committing to version control. PRIVACY This extension processes files entirely on your local machine. No data, files, or telemetry are sent to any server.
