The record

Purpose: IncidentRelay is open-source, self-hosted on-call management and incident response software for routing alerts, notifying responders, managing rotations and reducing alert noise.
Alert routing: It routes incoming alerts by source, labels, severity and team ownership, then applies escalation policies and team rules.
Scheduling: Teams can create on-call schedules, shifts, rotations, overrides and escalation chains.
Incident actions: Responders can acknowledge, resolve, silence or escalate alerts, and the documentation describes temporarily shelving alert groups.
Orchestration: Event orchestration can enrich, group, route, suppress and automate events using versioned rules.
Integrations: Documented alert sources include Alertmanager, AWS SNS and CloudWatch, Grafana, Azure Monitor, Zabbix, Sentry, LibreNMS and generic webhooks.
Automation API: IncidentRelay provides Swagger UI and OpenAPI JSON, with route intake tokens for incoming integrations and personal API tokens for user-scoped automation.
Access controls: The documentation describes group and team roles, including viewer, editor, user_admin, responder and manager.
Self-hosting: Installation paths include Docker Compose, an RPM package and manual systemd; production installations run separate web/API and scheduler processes.
Migration: The maker says its Grafana OnCall and PagerDuty migration tools use public APIs, avoid product databases and default to dry-run mode.
Intended users: The maker presents IncidentRelay for SRE and DevOps teams seeking self-hosted incident management and on-call workflows.
Event processing: Event orchestration can enrich, group, route, suppress and automate events, with execution history to inspect rule matches and results.
Alert integrations: Available 1.x incoming integrations include Alertmanager, AWS SNS and CloudWatch, Grafana, Datadog, Zabbix, Sentry, LibreNMS, RMON, generic webhooks, PagerDuty Events API v2 and heartbeats.
Notifications: Available delivery methods include Slack, Mattermost, Telegram, email, Discord, Microsoft Teams, outbound webhooks, voice calls and browser/PWA push.
