n8n monitoring — now real

Sentry for n8n workflows.

Catch failures. Stop silent errors. Protect the workflows that run your business.

What you get

Stop flying blind.

n8n tells you a workflow ran. FlowSignal tells you why it mattered — or why it failed.

Pain #1

Failure Inbox

Grouped by workflow and error type. See exactly which workflows broke and why — no grep required.

Pain #2

Silent Failure Detection

Expected output missing? Zero leads created? No CRM update? Empty webhook result? We catch what n8n doesn't flag.

Pain #3

Slow Workflow Detection

Identify bottlenecks before they become incidents. Pinpoint which node is dragging your workflow to a crawl.

AI Cost Estimate

See estimated AI API cost per workflow run. Know what you're spending on GPT-4, Claude, and every other AI node.

Slack + Email Alerts

Get notified immediately when something breaks. Route alerts to Slack, email, or both — per workflow.

Weekly Digest

Every Monday: failure summary, cost trends, and a workflow health snapshot. Know the state of your automations before the week starts.
