Stop Finding Out Your Automation Failed From an Angry Client
STACKSTER is a dead-man’s-switch for your workflows. Every run pings us — if a ping doesn’t arrive on schedule, you get alerted before your client does.
No credit card required · Free forever plan
Securing millions of webhook pings for modern automation teams
Built for how automation actually breaks
No agents to install, no dashboards to babysit. Add one HTTP node and we handle the rest.
Zero-friction setup
Drop an HTTP request node at the end of your workflow. GET, POST, or HEAD — no SDK, no extra auth, no new account to wire up.
Instant alerts
A missed ping fires an email the moment it’s overdue — not the next time someone happens to check.
Workflow “Invoice Sync” missed its ping
Expected 9:00 AM · no ping received
30-day log retention
Every ping is logged for a full month, so you can prove exactly when a workflow ran and when it didn’t.
This is a dead man’s switch
Your workflow pings on a schedule. As long as it does, we stay quiet. The moment it doesn’t, you find out first.
