n8n marks broken runs green. Error workflows aren't attached by default. Schedules die without a sound. n8proof grades any workflow free, then watches for the failures n8n calls "success" — and sends the alert to you, not your client.
No signup. No upload. Runs entirely in your browser.
Something noticed. The dangerous class is the run that stops doing its job with no error anywhere — and every one of these is documented, right now, in the n8n community.
Paste an exported n8n workflow. Eight checks, each mapped to a documented silent-failure mode, scored out of 100. Nothing is uploaded — the analysis runs in your browser.
We watch executions for the failures n8n calls success — swallowed errors, empty outputs, counts that quietly collapse from 500 to 5 — and page you the moment one lands.
A weekly report per client, in your branding: workflows watched, runs verified, issues caught before impact. The document that makes a retainer renew itself.
The scariest failure is the run that never happened. If an expected run doesn't appear, you hear about it in minutes — not when the client does.
Silent failures are the most-cited unsolved problem in the n8n community right now — here's what agencies and builders are saying, unprompted.
"Runs n8n marks green but broke… the usual signal never fires. A run can quietly stop doing its job and nothing pages you."
"The failure most teams miss is silence. Agencies lose trust when a workflow quietly stops delivering — not when it throws an error."
"How do you monitor n8n workflows in production and detect failures early?" — 24 replies, no consensus answer.
Numbers below are the founding structure. Final pricing is set with the first cohort — that's the point of a founding round.
Yes — and it's good. The free grader here is the same category, but n8proof's product isn't the grader. It's the ongoing monitor and the white-label client report, aimed squarely at agencies who need to prove reliability to the people paying the retainer. The grade is the front door; the report is the reason you stay.
An error workflow catches thrown errors. It does nothing for the failure class that matters most: runs that finish green having done nothing — swallowed errors, empty outputs, schedules that silently stopped. That's what n8proof watches, plus a dead-man's switch for the run that never fired at all.
No. Every check runs in your browser via JavaScript. The JSON you paste is never sent, stored, or logged anywhere. You can disconnect your network and it still works.
It reserves one of five founding spots and locks founding pricing for life. It's fully refundable — if we don't catch anything worth catching in your first month, you get it back and keep the reports. The deposit exists to filter for agencies who genuinely have this pain, not to make money on day one.
Five founding agencies, onboarded hands-on. Your workflows wired in, reports in your branding, founding price locked. Refundable deposit.
