Can I code PagerDuty?

A webhook that sends you a notification when something fails is genuinely simple. Reliable, escalating on-call alerting — trying person A, then B, then the whole team, at 3am, without fail — is where the real depth is.

Why CanICodeThis says Borderline

  • Sending yourself an email or SMS alert when a monitoring check fails, via an existing notification API, is a bounded integration
  • A simple on-call schedule (who's responsible this week) is ordinary CRUD
  • For a solo developer or small team, direct alerts to a known person cover real needs

What you give up building PagerDuty yourself

  • Escalation policies (try person A, wait 5 minutes, try B, then the whole team) need reliable, correctly-sequenced scheduled logic that can't silently fail
  • Guaranteed delivery across multiple channels (push, SMS, phone call) when an alert is truly critical needs redundant, tested infrastructure
  • Incident timeline tracking and post-mortem tooling is a real, separate feature beyond the alert itself

How to build your own PagerDuty

Build me a basic alerting tool: when a monitoring check fails, send a notification via an existing SMS or push API to a fixed on-call person. A simple weekly on-call schedule. Skip multi-step escalation policies for v1 — direct alerting to one person covers real small-team needs.

What it actually costs to build

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.

AI agent — with a subscription (Claude Pro/Max, Cursor, etc.)$0 marginal
AI agent — pay-per-use API, no subscription$43–$86 one-time
Hosting, once it's running$0/mo (free tier)
Domain name, if you want your own~$12/yr

PagerDuty costs $21/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 5 months.
