Paste valid Node-RED JSON
Exports are checked for Node-RED node IDs, types, positions and wire structure before they are stored.

Share automation flows without losing the visual context.
nodeBin is a free pastebin and visual library built specifically for Node-RED. Instead of sending an unexplained JSON file, you can publish a flow with a description, a copy-ready export and an interactive preview of its nodes and wires.
Choose public or private
Public flows join the searchable community library. Private flows receive an unlisted secret link.
Copy and import
Open a shared flow, inspect its visual layout and copy the original JSON back into the Node-RED editor.

Common questions
Node-RED flow sharing FAQ
What is a Node-RED flow?
A Node-RED flow is a collection of connected nodes that receives, transforms and sends messages. Node-RED exports flows as JSON, which can be imported into another compatible Node-RED editor.
Does nodeBin include passwords and credentials?
Node-RED normally stores formal node credentials separately, but custom nodes can still place tokens, hostnames or personal information in ordinary properties. Always inspect an export before publishing it.
Do I need an account?
No. Anonymous sharing is available, but older anonymous flows may be removed when nodeBin exceeds 1,000 stored flows. Flows attached to an active account are excluded from automatic capacity cleanup.
Can I share custom Node-RED nodes?
Yes. nodeBin accepts custom node types as long as the export has a valid Node-RED structure. Someone importing the flow must install the same node packages separately.
