Frequently asked questions
What is n8n Visualizer?
n8n Visualizer is a free online tool that takes any n8n workflow JSON and renders it as an interactive, color-coded node diagram — instantly, in the browser, with zero sign-up. You can pan, zoom, click nodes to inspect parameters, and export the diagram as PNG or SVG.
How do I export my n8n workflow as JSON?
Open your workflow in the n8n editor, click the three-dot menu (⋯) in the top-right corner, and select "Download" to save the workflow as a .json file. You can then paste that JSON into n8n Visualizer or drag and drop the file directly onto the page.
Is my workflow data sent to any server?
No. Every JSON parse, diagram render, and export happens entirely in your browser. Your workflow data never leaves your device — there are no server calls, no databases, and no analytics tracking your content.
What n8n node types are supported?
All n8n node types are supported. Each node is automatically color-coded by category: triggers (purple), actions (blue), logic/conditionals (amber), HTTP requests (teal), code/function nodes (gray), AI/LLM nodes (pink), and error nodes (red).
Can I use this on mobile?
Yes. n8n Visualizer is fully responsive. On mobile, the JSON input becomes a full-screen textarea, the diagram supports pinch-to-zoom and pan, and the node detail panel appears as a bottom sheet.
How do I share my workflow diagram?
Click the Export button on the canvas and choose "Copy Shareable URL" to get a link with the workflow encoded in the URL. You can also export as PNG or SVG to share as an image, or copy the workflow JSON back to your clipboard.
Does this work with n8n Cloud and self-hosted n8n?
Yes. As long as you can export your workflow as JSON (Settings → Download), n8n Visualizer can render it — whether you use n8n Cloud, a self-hosted instance, or n8n running locally.
What is an n8n workflow?
An n8n workflow is a sequence of connected automation steps built in n8n, an open-source workflow automation tool. Each step is a node (e.g., trigger, HTTP request, condition, action) linked together to define a data-processing pipeline.
How is this different from n8n's built-in editor?
n8n's built-in editor is for building and running workflows. n8n Visualizer is a lightweight, read-only tool for viewing, understanding, and sharing existing workflows — useful for documentation, onboarding, presentations, and debugging without needing an n8n instance.
Is n8n Visualizer free to use?
Yes. n8n Visualizer is 100% free with no usage limits, no sign-up required, and no hidden paywalls. It's a community tool built for the n8n ecosystem.
The free n8n workflow visualizer for every team
n8n Visualizer is the fastest way to visualize your n8n workflow as an interactive diagram. Whether you need an n8n JSON viewer to inspect a colleague's automation, an n8n workflow diagram tool for documentation, or simply want to understand your own workflow structure at a glance — this free tool does it all. No sign-up, no server, no data collection. Your n8n automation visualizer runs entirely in your browser.
What is an n8n workflow visualizer?
An n8n workflow visualizer is a tool that converts your n8n workflow JSON into a visual node diagram. Instead of reading through dozens of JSON lines to understand how your automation flows, you see a clean, color-coded map of every node and connection. The n8n workflow graph shows triggers, actions, conditions, HTTP requests, code nodes, and AI/LLM steps — each rendered as an interactive card you can click to inspect parameters.
n8n Visualizer goes beyond basic n8n JSON visualization. Click any node to open a detail panel showing the node type, version, all configured parameters, credentials used, and a plain-English explanation of what the node does. This makes it the most complete n8n workflow inspector available — perfect for debugging, onboarding new team members, or reviewing automations before deploying them to production.
How to visualize your n8n workflow
Getting started takes seconds. Open your workflow in the n8n editor, click the three-dot menu in the top-right corner, and select "Download" to export the workflow as JSON. Then come to n8n Visualizer and paste the JSON into the textarea, drag and drop the .json file anywhere on the page, or click the upload area to select a file. The tool validates your JSON in real time and renders the n8n workflow diagram instantly.
Once rendered, you can pan the canvas by dragging, zoom with your scroll wheel or pinch gestures, and use the minimap in the bottom-right corner to navigate large workflows. Every node is color-coded by type: purple for triggers, blue for actions, amber for logic and conditionals, teal for HTTP requests, gray for code and function nodes, pink for AI and LLM nodes, and red for error nodes. This n8n workflow visualization makes it easy to spot bottlenecks, broken connections, or missing nodes at a glance.
Export and share your workflow diagram
n8n Visualizer includes powerful export options that make it easy to share your n8n workflow documentation. Export the diagram as a high-resolution PNG for presentations and documentation, or as an SVG for scalable vector graphics that look sharp at any size. Copy a shareable URL that encodes the workflow directly in the link — perfect for sending to teammates or embedding in docs. You can also copy the workflow JSON back to your clipboard with one click.
Works with n8n Cloud and self-hosted n8n
As long as you can export your workflow as JSON, n8n Visualizer can render it. This means it works with n8n Cloud, self-hosted n8n instances, and n8n running locally. Whether you use the n8n community edition or the enterprise version, this n8n workflow converter handles it all — no server calls, no API keys, no authentication required.
