Monitor [PROD] workflows in real time with the n8n Public API dashboard

Description

A real-time monitoring dashboard for your n8n production workflows, accessible directly from the browser via webhook.

Tag any workflow with [PROD] and it will automatically appear on the dashboard showing:

→ Healthy vs error workflows
→ Success rate per workflow
→ Total errors and successes
→ Last error timestamp
→ 7-day error history chart

The dashboard auto-refreshes every 30 seconds. No external tools required — it uses only the n8n Public API.

How it works

When the webhook is triggered, the workflow:
Fetches all workflows tagged [PROD] via the n8n API
Retrieves the last 50 executions (success + error) for each workflow
Calculates metrics and renders a dark-themed HTML dashboard
Returns the dashboard directly in the browser

Requirements

n8n self-hosted (any version with Public API enabled)
n8n API credential configured
At least one workflow tagged [PROD]

Setup

Enable the n8n Public API under Settings → API
Create an n8n API credential with your API key
Open the Config node and set your n8n base URL
Connect the credential to all HTTP Request nodes
Activate the workflow and open the webhook URL in your browser
