For indie AI & no-code builders

Your automation said "success." Your sheet says nothing.

Point us at the Google Sheet your automation fills. We alert you when rows don't show up, show up empty, or arrive late.

Works with n8n, Zapier, Make, or scripts, because we check the destination sheet, not the workflow.

Free pilot opening soon → Monitor up to 3 sheets, no account needed. Join the waitlist to get access first.

Thanks! You're on the list. We'll email you when early access opens.

Green checkmarks don't mean rows were written

Automations can report success for days while writing zero rows: an expired token, an empty upstream response, a renamed column. Nothing errors, so nothing alerts you.

✔ Run #4182 succeeded   Mon 09:00   duration 3.1s
✔ Run #4183 succeeded   Tue 09:00   duration 2.9s
✔ Run #4184 succeeded   Wed 09:00   duration 3.0s
→ Rows written to "Leads": 0

How it works

1

Publish one tab as CSV

In Google Sheets, use File → Share → Publish to web → CSV and paste the link. We only download that CSV; we can never change your sheet.

2

Pick what matters

Choose the sheet, the timestamp column, the columns that must be filled, and the deadline.

3

Get alerted

If rows are missing, empty, or late, you hear about it before your users or clients do.

What an alert looks like

⚠ Missing rows: Leads

Your Leads sheet got 0 new rows today. Last valid update: yesterday 9:02 AM.

Deadline: 10:00 AM · Required: email, source

Heartbeats prove it ran. We check what it wrote.

Heartbeat monitors

Ping when a job starts or finishes. A run that writes nothing still looks healthy.

SheetSentry

Checks the destination sheet itself: did rows arrive, are required fields filled, and did they arrive on time?

FAQ

What data can you access?

Only the CSV of the tab you publish to the web. We download it read-only every 15 minutes; we never get access to your Google account. Note: a published CSV link can be read by anyone who has it.

Will you ever edit my sheet?

No. We never edit, add, or delete anything in your sheet.

What about days with no data on purpose?

You can mark quiet days (weekends, holidays) as allowed so they don't trigger alerts.

Which tools does it work with?

Any tool that writes to Google Sheets: n8n, Zapier, Make, custom scripts.

How much does it cost?

Early pricing: Starter $29/mo for 3 monitored reports, Business $79/mo for 15, Agency $199/mo for 50. Paid plans and the free pilot (up to 3 monitors) open soon: join the waitlist to be notified.
