StackWitness vs PagerDuty: detection and status, not just paging
PagerDuty sits downstream of detection. It receives alerts from the tools you connect and routes them to the right person with schedules and escalation. StackWitness sits upstream: it measures the dependencies you rely on first-hand from multiple regions, monitors your own endpoints, tells you whether it is them or you, and publishes a status page from the same readings.
These are two different jobs in one outage. The honest question is not which is better, but which job you need solved first, and whether one tool can cover it for your team size.
Two different jobs in one outage
Where each one sits in an outage
| PagerDuty style | StackWitness | |
|---|---|---|
| Primary job | Route and escalate alerts to on-call humans | Detect the outage independently and show it honestly |
| Where the signal originates | Ingested from the monitoring tools you connect | Measured first-hand from multiple regions, with the vendor feed alongside |
| Answers "them or us?" | Depends on what the connected tools report | Designed for that question on your dependencies |
| Customer-facing status | Add-on page fed by your incidents | Status page backed by the same outside measurement |
| On-call and escalation depth | Deep: rotations, overrides, multi-step escalation | Built-in alerting and escalation on paid plans, lighter than a dedicated platform |
How to choose
- You need deep on-call orchestration across many teams. A dedicated incident-response platform goes further on rotations, overrides, and multi-step escalation.
- You need to know the truth first, then alert a small team. StackWitness detects, attributes, alerts, and publishes a status page in one place, which is often enough before you add a separate paging platform.
- You want both. Many teams route StackWitness alerts into an incident tool. You still get first-hand, multi-region measurement and a status page from the same readings.
Where StackWitness fits
StackWitness is independent dependency and uptime monitoring with honest status pages. We measure the services you depend on ourselves, from multiple regions, and read the vendor's own status feed alongside, so when something breaks you know within minutes whether it is your provider or you. When our regions disagree, we show it as measured instead of averaging it into a comfortable green.
The paid product gives you your own monitors, clear attribution the moment a third party is the cause, and a customer-facing status page backed by that same measurement. It is the evidence you want in front of customers and your own team at 3am.

Questions
Is StackWitness a replacement for PagerDuty?
For a small team it can cover detection, alerting, and a status page in one place, which may be all you need. For large organizations with formal on-call across many teams, a dedicated incident-response platform goes deeper on paging. The two also work well together: StackWitness detects and attributes, your incident tool routes the humans.
Can I send StackWitness alerts into an incident tool?
Yes. StackWitness delivers alerts to Slack and to a webhook, so you can forward them into whatever routes your on-call. You still get first-hand, multi-region measurement and a status page from the same readings.
Does StackWitness tell me whether it is my provider or me?
That is the core of it. We probe the real dependency host from multiple regions and read the vendor status feed alongside, so within minutes you can tell whether a third party is down for everyone or the problem is inside your network.
Start with evidence you can read. Public dependency truth pages use the same measurement discipline as the paid product.
