## What it is
GoAlert is an open-source on-call scheduling and alert escalation application that automatically notifies the right person via SMS, voice calls, email, or Slack when critical alerts fire. It is distributed as a single Go binary or Docker image and integrates with monitoring tools like Grafana, Prometheus, Sensu, and Site24x7.

## Use cases
- schedule on-call rotations for my engineering team
- automatically escalate alerts when the on-call person doesn't respond
- send SMS and voice call notifications for critical incidents
- self-hosted PagerDuty alternative for incident alerting
- integrate Prometheus or Grafana alerts with on-call escalation
- manage escalation policies and service schedules from a web UI
- notify the right engineer in the middle of the night without missing alerts

## When to choose
- you want a self-hosted, open-source alternative to PagerDuty or Opsgenie
- your team needs on-call rotations, overrides, and automated escalation policies
- you need SMS, voice, email, or Slack notifications driven by existing monitoring tools
- you prefer a single deployable binary or Docker container with a web UI and API

## When to avoid
- you only need simple email alerts without scheduling or escalation logic
- you want a fully managed SaaS with no infrastructure to host
- your notification channels require providers beyond Twilio, Mailgun, or Slack without custom integration work
- you need a lightweight CLI-only alerting tool rather than a full web application
