Automation output monitoring
SignalSitter watches the outputs of automations and background jobs. Send a heartbeat or shallow numeric JSON; when an expected signal is missing or a deterministic numeric rule is violated, SignalSitter tells your software.

Product
Watch the outputs that matter.
SignalSitter is purpose-built for expected signals from automations and background jobs—not the infrastructure underneath them.
Heartbeat monitoring
Expect a simple HTTPS signal at the interval your work needs. A missing expected signal becomes an incident.
Deterministic numeric rules
Send shallow numeric JSON and evaluate deterministic rules you define—nothing learned or inferred.
Explainable incidents
Each incident is tied to the expected signal that went missing or the numeric rule that was violated.
Agent-native administration
Administer monitors through the dashboard, REST API, or remote MCP—wherever your team works.
How it works
Three steps. One clear contract.
Configure what should happen. Send the signal from your work. Receive a signed callback when expectations are violated.
01
Create a monitor
Set the expected heartbeat or deterministic numeric rule.
02
Send a signal
Your automation sends an HTTPS heartbeat or shallow numeric JSON.
03
Receive a signed callback
When the expectation is violated, SignalSitter reports it to your software through a signed, retried webhook.
Example signal
curl -X POST https://ingest.signalsitter.com/nightly-backup -H ‘Authorization: Bearer YOUR_TOKEN’ -H ‘Signalsitter-Interval: 300’ -H ‘Content-Type: application/json’ -d ‘{“backup_bytes”:8589934592}’
Who it is for
Built for the people closest to the work.
Developers & small SaaS teams
Keep an eye on backups, data syncs, and scheduled reports without watching the underlying stack.
Automation agencies
Watch workflows built with cron, n8n, Make, Zapier, and custom automation systems.
AI agents & coding agents
Administer systems for their owners, including simple agent check-ins, through remote MCP or the REST API.
Security & privacy
Careful by design.
Tenant scope comes from verified identity. Secrets are shown once and redacted later. Callback destinations are checked before delivery. Observation history is bounded by the active plan.
Privacy information
Where information is held.
Monitor data—observations, incidents, and configuration—is stored in the EU jurisdiction selected for the monitor. The control plane is EU-resident. Identity data such as name and email is held by Clerk in the United States under the EU–US Data Privacy Framework.
SignalSitter does not use an analytics provider, session recording, or a model provider for customer monitoring data.
Service boundaries
Clear expectations, clearly stated.
SignalSitter detects and reports expectation violations; it does not execute remediation. SignalSitter is not intended for medical monitoring or life-safety control. Reliability figures are targets we measure, not contractual guarantees; no service credits or contractual SLA are offered. Formal terms of service are not yet published.
