Instantly audit your n8n workflow — free
Export your workflow (⋯ → Download) and paste the JSON. Five production-critical checks run locally in your browser — nothing is uploaded, nothing is stored.

NewThe Pro auditor just grew to 24 production rules — test-drive the free 5 below.
The silent killers this page catches
The workflow “works” — in the editor only
In submission or queue mode a localhost URL or a credential that exists on YOUR machine silently resolves to nothing. The run never fires. The fix is pattern-checking your exported JSON before deploy — exactly what this page does.
Open webhooks as free API keys
A workflow importing a Webhook node with no auth header is reachable by anyone who guesses or scrapes the URL. One of the five checks flags any webhook left unauthenticated before production finds out the hard way.
Secrets camping inside the export
Exported JSON frequently keeps hardcoded tokens, basic-auth passwords and API keys in plain text. If that file ever leaves your machine — GitHub, Discord, a client handoff — the key goes out with it. The audit scans both node names and value patterns.
Free checker vs. the full dashboard
The free checker is not a crippled demo — it is genuinely useful. The dashboard is for the person whose invoice depends on n8n never silently dying again.

Questions smart self-hosters ask
Is it really free — and is my workflow JSON safe?
Yes. The five rules run inside a sandboxed script in your own browser tab on the pasted text. No network request carries your JSON anywhere, there is nothing to sign up for, and we could not see your workflows even if we wanted to.
What does the $39 dashboard add that is worth paying for?
Depth (24 rules instead of 5), repair (one-click auto-fix for the common safe fixes), and packaging: a client-ready PDF report plus the QA checklist and fix trees that turn “the workflow failed” into a two-minute deliverable for your clients. It pays for itself with one saved afternoon.
Will it generate false alarms?
The rules are deterministic pattern checks on your JSON — when something is flagged, the exact line or node is shown with why. Treat findings as high-quality review prompts, not verdicts; the report tells you how to confirm each one.
