Know when your n8n
workflows stop running.
n8n has no native alert for “this workflow hasn’t run in 24 hours.” Most teams find out when a customer asks.
Free plan available. No credit card required.
| Workflow | Status | Last run | Threshold |
|---|---|---|---|
| example_invoice | MISSING | 3d ago | 24h |
| example_report | OK | 2h ago | 24h |
| example_sync | OK | 14m ago | 1h |
| example_enrich | FAILED | 45m ago | 2h |
FlowGuard never writes to your n8n. Read access is enough to see execution timestamps.
API keys are encrypted before storage and decrypted only at check time.
Three steps,
then it just runs.
Auto-import on first sync
Paste your n8n URL and API key. Watchdog enumerates every active workflow and starts tracking execution timestamps. No code, no webhooks, no agent.
Per-workflow silence window
Define how long each workflow can go quiet before it counts as broken. From one minute (Pro) or one hour (Free) to thirty days — your call, per workflow.
Email before your client does
The moment a workflow goes past its threshold, you get a mail with the last execution time and a direct link into n8n.
One dashboard, every instance
Run multiple n8n instances? See them in one table. Sort by status, filter by instance, fix the broken one — without tab-switching.
60 seconds to set up.
First alert pays for the year.
Free plan: 5 workflows, 1 instance. No credit card.
