n8n Reliability Toolkit Pro — Preflight + Incident Doctor

Catch avoidable n8n workflow problems before deployment, then turn failed executions into a repeatable incident-review process.

n8n already gives you execution history, retry options, and Debug in editor. This toolkit is built for the work around that: deterministic preflight checks before you ship and structured diagnosis when failures start piling up.

Best fit for

• Freelancers and agencies handing n8n workflows to clients.
• Teams that want a repeatable pre-deployment review instead of relying on visual inspection alone.
• Builders debugging multiple failed executions who want structured triage without sending workflow contents to an external AI service.

What you get

• Deep preflight scanner with Markdown and JSON reports.
• Broken-connection checks to surface missing or inconsistent workflow links before deployment.
• Secret/auth review signals plus external-domain and credential inventory for a clearer dependency picture.
• GitHub CI template for repeatable preflight checks in a code-review workflow.
• Sample reports so you can inspect the expected output format before relying on it.
• n8n Failed Execution Doctor Pro for structured batch diagnosis after failed runs.

A practical workflow

1. Before deployment: run the preflight scanner and review the generated findings.
2. After a failure: use n8n’s execution history / Debug in editor for the exact failed run.
3. When failures become repetitive or numerous: use Incident Doctor Pro to organize exported failure data into a consistent triage report.
4. Before the next release: keep the preflight step in your review or CI process so the same class of avoidable issue is less likely to return.

What this does not do

• It does not execute or modify your n8n workflows.
• It does not replace n8n’s native execution log or Debug in editor.
• It does not require an external LLM for diagnosis.
• It does not require a live n8n login for the local analysis described above.

Privacy and operating model

The preflight scanner does not execute workflows, call external APIs, upload workflow contents, or require n8n credentials. Incident Doctor Pro requires no external LLM, API key, database, or live n8n login for diagnosis.
